Femtogram-level VEGF detection via PEG-directed gold nanostructured electrochemical immunosensor

Abstract This study presents a novel electrochemical immunosensor designed for the highly sensitive detection of vascular endothelial growth factor (VEGF). The sensor utilizes gold nanostructures grown on fluorine-doped tin oxide (FTO) electrodes through a polyethylene glycol (PEG)-mediated electroc...
