Sequential trapping of single nanoparticles using a gold plasmonic nanohole array
Xue Han, Viet Giang Truong, Sile Nic Chormaic
We have used a gold nanohole array to trap single polystyrene nanoparticles, with a mean diameter of 30 nm, into separated hot spots located at connecting nanoslot regions. A high…
