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...
