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 on one hand at tailoring nanostructures to attain controlled biological interfaces, while on the other hand at characterizing biological systems with a high resolution on the nanoscale. After soft-landing under clean vacuum conditions on substrate using the unique electrospray deposition method developed in the department, individual biomolecules can be imaged by scanning probe microscopy, local magnetic resonance techniques and low energy electron holography with ultimate resolution.

Theoretical landscape methods are employed to analyze, interpret and predict the stability, the adsorption conformation and the possible self-assembly structures of biomolecules on supporting surfaces.
