摘要：
Herein, we report a novel clustered regularly interspaced short palindromic repeats (CRISPR)/Cas-mediated chemiluminescence assay (CRISPR-Cas-CLA) for the ultrasensitive detection of viral nucleic acids of HPV18 and HPV16. The CRISPR-Cas-CLA comprises a CRISPR/Cas12a system that specifically recognizes the target nucleic acid, a signal-conducting nanoconjugate (MB-ssDNA-PSNP) formed by coupling singlet-oxygen ((1)O(2))-generating photosensitive nanoparticles (PSNPs) to magnetic beads (MBs) via a single-stranded DNA (ssDNA) linker, and (1)O(2)-activated chemiluminescence nanoparticles (CLNPs). In the presence of the target nucleic acid, the ssDNA linker of the nanoconjugate is cleaved by the target-activated CRISPR/Cas12a system, and the PSNPs are dissociated from the MBs. The PSNP-containing supernatant obtained by magnetic separation is added to the CLNP-coated detection plate. Upon light irradiation of the CLNP-PSNP mixture in the well, strong chemiluminescence is generated with the subsequent addition of hydrogen peroxide, enabling the detection of the target nucleic acids. The proposed CRISPR-Cas-CLA system offers ultrahigh sensitivity (∼1.04 aM), simple operation, and low cost, providing a new direction for the development of PCR-free detection strategies for ultralow abundance nucleic acids.

摘要：
We present a flexible scheme enabling reversible switching of topological states and dynamic modulation of optical bistability in a fixed micro-nano nonlinear optical system. The system realizes the optical modulation of reconfigurable topological edge states through phase transition-induced optical property changes in Ge2Sb2Te5. The third-order nonlinear optical effects of the system are effectively enhanced by local field enhancement in the dual-band via reconfigurable topological edge states, which have a positive impact on the realization of dual-channel modulated optical bistability. In particular, electric field distributions within parameter subspaces are mapped to demonstrate multi-degree-of-freedom dynamic control of OB under fixed pump intensity by tuning graphene's Fermi level, relaxation time, layer number, and incident angle. Meanwhile, the simulation results agree well with the calculation, proving that the modulated dual-channel optical bistability via reconfigurable topological edge states based on phase change materials can be achieved, which provides a viable solution to address the lack of multidimensional optical modulation of fixed micro-nano nonlinear optical systems in the mid-infrared band.

摘要：
The use of data fusion based with multiple analytical techniques was investigated to provide the accurate geographical origin identification of Atractylodes macrocephala Koidz. (AMK). Inductively coupled plasma - mass spectrometry (ICP-MS), gas chromatography - mass spectrometry (GC-MS) and liquid chromatography - mass spectrometry (LC-MS) were used to characterize Hubei, Zhejiang, and Hunan production regions. After the implementation of data fusion, the ensemble learning method multi-forest joint network (MFJN) and classic machine learning methods were used to identify the AMK production regions. The MFJN based upon high-level data fusion distinguished AMK samples from different regions with the highest accuracy. The classification accurate rate of AMK in the prediction set was 95%, which was significantly better than the results obtained using twenty-five mineral element or nine bioactive component data sets. The results showed that mass spectrometry data fusion in combination with MFJN is suitable for the geographic origin determination of AMK and has potential to ensure this product’s fair trade.

摘要：
Reductive functionalization of aldehydes and ketones is one of the most challenging but ultimately rewarding areas in synthetic chemistry and related sciences. We report a simple and extremely versatile carbonyl reductive functionalization strategy achieving direct, highly selective, and efficient reductive amination, etherification, esterification, and phosphinylation reactions of (hetero)aryl aldehydes and ketones, which are extremely challenging or unattainable to achieve by traditional strategies, using only diphenylphosphine oxide and an inorganic base. It enables modular synthesis of functionally and structurally diverse tertiary amines, ethers, esters, phosphine oxides, etc., as well as related pesticides, drug intermediates, and pharmaceuticals. Compared to phosphorus-mediated name reactions, this strategy firstly transformed C═O bonds into C-element single bonds. Mechanistically, phosphinates are formed as intermediates, which undergo unconventional nucleophilic substitution at the C atom within their C─O─P unit. Thus, this work provides important strides in the field of reductive functionalization of aldehydes/ketones, phosphorus-mediated transformation, and various fundamental reactions.
摘要：
Circulating tumor cell (CTC) assays with single-cell sensitivity and efficient implementation are critically needed in clinic applications, especially for cancer screening. We report a novel proximity-enabled singlet-oxygen chemiluminescence assay (PESCA) that enables low-cost and efficient CTC detection with single-cell sensitivity. The PESCA system is based on proximity labeling of cell-surface oncoprotein markers on CTCs using two types of polymer nanoparticles, one for generating singlet oxygen ((1)O(2)) and the other for activating chemiluminescence upon (1)O(2) sensitization and H(2)O(2) decaging. A hybridization chain reaction (HCR) is exploited for triggering the proximity labeling, allowing efficient sensitization of the chemiluminescence signal specific to CTCs with signal amplification to enable robust single-cell resolution. The PESCA method can accomplish digital counting of CTCs in a whole blood sample with a detection efficiency of 80% for 10 CTCs in 7.5 mL of whole blood, highlighting its potential for cancer screening in clinic applications.
摘要：
Human immunoglobulin (HIgG) has gained recognition as a crucial biomarker diagnosing and treating various diseases, particularly in identifying elevated serum levels in conditions like measles and pneumococcal disease. Traditional detection methods, however, are often hindered by inefficiencies, high costs, and potential inaccuracies, underscoring the urgent need for more sensitive, efficient, accurate, and self-calibration methods for HIgG. Here, a novel ZnIn2S4/SnO2 composites was synthesized, featuring uniformly dispersed SnO2 nanoparticles on the flower-like ZnIn2S4 structure, resulting in a type II heterojunction that promotes the separation and transfer of photogenerated carriers. Under optimized conditions, this composite demonstrated remarkable photocurrent enhancements 52 and 195 times greater than that of the individual ZnIn2S4 or SnO2, respectively. A novel dual-mode biosensing platform was subsequently developed, employing the ZnIn2S4/SnO2 composites as both as the photoelectrochemical (PEC) signal generator and antibody carrier. This system utilizes multifunctional CuO NPs with ascorbic acid oxidase-like properties, serving as a secondary antibody label. Upon specific binding to HIgG, a notable decrease in the PEC response occurs due to the catalytic activity of CuO NPs and the antigen-antibody interactions. The introduction of o-phenylenediamine (OPD) further enhances detection by facilitating the formation of a fluorescent substance DHAA. This dual-signal approach yielded excellent linear correlations between both PEC and fluorescence signals and HIgG concentration, achieving low detection limits of 22.5 pg/mL or 8.6 pg/mL. These two signals originated from the same PEC electrode with continuous detection in the absence and presence of OPD, simplifying experimental procedures and enhancing the reliability of detection. The non-toxic, chemically stable ZnIn2S4/SnO2 composites ensures reliable and sensitive detection through photocurrent output after incubation with biomolecules. The integration of nanozyme catalysis, biospecific reactions, and in situ fluorescent products generation promise high selectivity across diverse immunosensing applications.

摘要：
We investigate the stability and characteristics of vortex quantum droplets (QDs) with particle imbalance and different topological charges S ± in two components formed by binary Bose–Einstein condensates trapped in a ring potential. Two types of binary vortex QDs including semi-vortex (SV) and mixed-vortex (MV) QDs can be stable up to at least S − = 14 with the help of the ring potential. It is worth noting that, for a given number of particles in the binary vortex QDs, the more particles are concentrated in the zero-vorticity and lower-vorticity components for stable SV and MV QDs, respectively, and the imbalanced degree is further increased with the growth of topological charge S − . We found that the relative norm (scaled number of particles) distribution of two components in imbalanced SV and MV QDs with high topological charge can be controlled by adjusting the ring potential radius, width, and depth. In addition, it is revealed that stable binary vortex QDs in the ring potential can violate the Vakhitov-Kolokolov criterion. Effects of the topological charges S ± and the ring potential parameters on the chemical potential and the peak density of the SV and MV QDs are systematically studied. The stability areas of the SV and MV QDs with different topological charges in the plane of the total norm and coupling constant are also identified. The results may be relevant to design an encoding device employing binary vortex QDs with different topological charges for storing different data components.

摘要：
Herein, a novel two-photon excited fluorescent sensor for the detection of zinc ions in aqueous solution as well as in cells was synthesized by the complexation process using an aggregation-induced emission (AIE) fluorophore. The near-infrared AIEgen chemosensor containing Schiff base derivatives with a salicylaldehyde moiety showed a distinctly selective response to zinc ion. The tetraphenylethylene quinoline benserazide probe based on tetraphenylethylene structure complexed zinc ions and then aggregated in aqueous buffered solution, causing the remarkable off–on enhancement of red emissions at 650 nm. Furthermore, this fluorescent molecule easily penetrated the cytomembrane and successfully achieved the intracellular zinc ion imaging of living cells.

摘要：
A switchable enhancement group delay in the terahertz band based on a novel sandwich topology protection structure with graphene is proposed in this paper. The notable phase transition of the reflected beam comes from the topological edge-protected mode excited at the sandwich photonic crystal surface, and the non-trivial topology of the photonic crystal allows the structure to be immune against defects and imperfections, which lays the foundation for the enhancement of group delay in the terahertz band. And the introduction of graphene creates favorable conditions for the reversible switching of positive and negative reflection group delay. Moreover, the reflected group delay can also be flexibly and dynamically controlled by the incident angle. The positive and negative reversible switching reflected group delay proposed in the terahertz band greatly reduces the optical transmission loss and significantly increases the transmission efficiency compared with the traditional metal sandwich structure, which provides a feasible idea for the realization of multi-dimensional manipulation of the wavelength and phase of electromagnetic waves in the terahertz band. The novel scheme is expected to provide potential applications in fields such as optical buffers or ultrafast modulators.

摘要：
We investigate reconfigurable reflected group delay in dual-band of the photonic crystal heterostructure containing phase transitions material Ge 2 Sb 2 Te 5 and graphene in mid-infrared region. The giant phase change of reflected beam derives from the topological edge state excited at the boundary surface of photonic crystal. Meanwhile, the tunable topological edge states can be satisfied by controlling the reversible switching between the crystalline and amorphous states of the Ge 2 Sb 2 Te 5 , which provides a flexible way to achieve configurable group delay in dual-band. Besides, the reflected group delay can be dynamically controlled by controlling Fermi energy, relaxation time of graphene and the incident angle. The reconfigurable reflected group delay in dual-band presented in this paper has the potential to be used in high-efficiency memory for optical pulses and optical delay lines.

摘要：
We theoretically present a flexible method to obtain dual-channel optical bistability (OB) in a coupled system consisting of a metallic nanoshell (MNS) and a carbon nanotube (CNT) nanomechanical resonator (NR) beyond the dipole approximation. The MNS is made of a metallic core and a dielectric shell. The results show that, the four-wave mixing signal is suppressed significantly due to multipole polarizations in comparison to that in the dipole approximation. Also, the four-wave mixing signal can be enhanced greatly with the exciton-phonon coupling strength g increasing. Especially, bistability phase diagrams plotted show that, for a given shell thickness, it is realizable to achieve one (or two) bistable region(s) by adjusting the pumping intensity (or the MNS-NR distance). In a strong exciton-plasmon coupling regime, OB can be switched from single-channel to dual-channel by only changing the dielectric shell thickness or the metallic core radius. This indicates that the system proposed can behave as a channel-tunable bistable switch. Our findings may have potential applications in various domains such as quantum communication and optical functional devices.
摘要：
Sb-based materials exhibit considerable potential for sodium-ion storage owing to their high theoretical capacities. However, the bulk properties of Sb-based materials always result in poor cycling and rate performances. To overcome these issues, pyridine-regulated Sb@InSbS3 ultrafine nanoplates loaded on reduced graphene oxides (Sb@InSbS3@rGO) were designed and synthesized. During the synthesis process, pyridine was initially adopted to coordinate with In3+, and uniformly dispersed In2S3 ultrafine nanoplates on reduced graphene oxide were generated after sulfidation. Next, partial In3+ was exchanged with Sb3+, and Sb@InSbS3@rGO was obtained by using the subsequent annealing method. The unique structure of Sb@InSbS3@rGO effectively shortened the transfer path of sodium ions and electrons and provided a high pseudocapacitance. As the anode in sodium-ion batteries, the Sb@InSbS3@rGO electrode demonstrated a significantly higher reversible capacity, better stability (445 mAh<middle dot>g(-1) at 0.1 A<middle dot>g(-1) after 200 cycles and 212 mAh<middle dot>g(-1) at 2 A<middle dot>g(-1) after 1200 cycles), and superior rate (210 mAh<middle dot>g(-1) at 6.4 A<middle dot>g(-1)) than the electrode without pyridine (355 mAh<middle dot>g(-1) at 0.1 A<middle dot>g(-1) after 55 cycles and 109 mAh<middle dot>g(-1) at 2 A<middle dot>g(-1) after 770 cycles). Furthermore, full cells were assembled by using the Sb@InSbS3@rGO as anode and Na3V2(PO4)(3) as cathode, which demonstrated good cycling and rate performances and exhibited promising application prospects. These results indicate that adjusting the microstructure of electrode materials through coordination balance is A<middle dot>good strategy for obtaining high-capacity, high-rate, and long-cycle sodium storage performances.

A novel AIEgen molecular probe (N-3QL) with typical AIE effects, good biocompatibility, lysosome targeting, pH activation, excellent photostability, and high brightness was synthesized using two simple synthetic steps.
