Here, the use of functionalized Si3N4 nanopores 
for the detection of negatively charged gold nanoparticles from 2.4 to 8.9 nm diameter.
It is possible to detect the surface molecular interactions through ionic current alterations, whether or not the electric-field driven nanoparticle threads through the pore.
Electrophysiological Study of Single Gold Nanoparticle/a-Hemolysin Complex Formation: A Nanotool to Slow
Down ssDNA Through the a-Hemolysin Nanopore**
Yann Astier,* Oktay Uzun, and Francesco Stellacci
Our NanoTool is able to capture a single gold nanoparticle under 3 nm in diameter, and use it as a speed regulator during the threading of ssDNA through the NanoPore. New improvements on this system will be published soon...
