Ultra-thin Silicon-on-Insulator films, in the pseudo-MOSFET configuration, have been used to detect the presence of charged gold nanoparticles on their top free surface. The detection is based on the coupling between the free surface and the channel created at the silicon film - buried oxide interface. The presence of the charged particles on the free surface induces shifts in the electrical characteristics...
In this work, we report a portable microfluidic chip based on gold nanoparticle-enhanced electrochemical detection for single-bacteria diognostic. The possibility of single-bacteria detection is realized here by using electroactive molecules modified on gold nanoparticles (NPs) to detect and differentiate Staphylococcus aureus and Pseudomonas aeruginosa. The detection limit of these two electroactive...
