Novel approachs to functionalize carboxylated multi-walled carbon nanotubes (CMWCNTs) array with poly-l-histidine (PLH) on a self-assembled monolayer (SAM) of 4-aminothiophenol (4ATP) were developed for the first time. With help of π–π interaction and chelation of the side imidazole groups in poly-l-histidine, the array showed efficient electron transfer and mild biocompatibility. By immobilizing...
We have developed an effective strategy to fabricate a novel non-enzymatic nitrite sensor. Copper nanodendrites (Cu-NDs) and reduced graphene oxide (RGO) were successively deposited on glassy carbon electrode (GCE) via a simple and two-step electrodeposition method. The fabricated sensor showed an excellent electrocatalytic activity for nitrite reduction. Moreover, the effects of electrodeposition...
