A facile and efficient electrochemical platform based on multi-walled carbon nanotube (MWCNT)-poly-L-lysine (PLL) hybrids was prepared for studying on the immobilization and in vitro electrochemical behavior of cells. The PLL/MWCNT hybrids form a reticulate structure on the electrode surface, which provides a biocompatible and efficient microenvironment for cell immobilization. In contrast to the cells/glass carbon (GC) electrode, the cells/PLL/MWCNT hybrid-modified GC electrode exhibits a negatively shifted peak potential and a greatly enhanced peak current, indicating better electrochemical ...
