Meet Sergio sergio-profile

Name: Sergio Santos Hernandez
Research interest: Nanoscale Processes

Research Summary

The following are my main research interests:
• Temporal and spatial study of water interactions in the nanoscale
• Intelligent surfaces and their applications (SAMs)
• Nanoscale Biological Processes
• The use of Biology in microfabrication and biological mimicing

My research is based on the fundamental laws governing nanoscale processes. In particular, it is focused on energy dissipation processes and water interactions in the nanoscale where I use the AFM as the main tool.
