Case 1: Polyaniline (PANI)/Polycrystalline Gold Composites
The biocompatible conductive polymer polyaniline (PANI) is a low-cost conductive polymer. PANI coatings can be used to create biological interfaces that improve cell-electrode communication in functions like nervous system patterning and recording.
Alfa Chemistry employs a three-step process to achieve stable and homogenous coatings: (1) 4-nitrophenyl group functionalization of the gold surface, (2) electrochemical reduction of nitro to amines, and (3) aniline electropolymerization of aminophenyl modified gold electrodes on the surface.
Case 2: Polyethylene glycolized gold nanoparticles (AuNP)
PEG is frequently used to protect adenovirus (Ads), ablate Ad-loving, and enhance tumor formation. Alfa Chemistry's polyethylene glycolized AuNPs offer good potential for use as Ad vector coatings to improve CAR-negative cell transduction.
