Abstract:
Label-free biosensors based on in situ formed and functionalized TTF-Au wires were developed using an integrated microfluidic system. By applying different modification protocols, TTF-Au wires were successfully used for sensitive label-free detection of catecholamines and human IgG by Raman spectroscopy.
