Nano-Bio Interfaces

Nanoscale tools serve as ideal interfaces to interrogate biological systems since the sizes of many nanostructures are comparable to that of typical biomolecules. The activities in this research direction are aimed at characterizing biomolecules with a high resolution on the nanoscale. Individual biomolecules are soft-landed under clean vacuum conditions on substrate using the unique electrospray deposition method developed in the Department, and subsequently imaged by scanning probe microscopy and low energy electron holography with ultimate resolution.
