In our research, we set the goal of understanding and controlling interactions in chemical systems at small scale (microns to nanometers to single molecules). The research is interdisciplinary, where approaches of chemistry, physics, and engineering converge. In particular, force spectroscopy can manipulate single molecules and perform mechanical experiments at nanoscale; thus, one can move beyond ensemble averages to resolve and analyze transient subpopulations, study details of energy landscapes, and observe mechanics of molecular machinery of cells. We are developing new, simple approaches to the analytical force spectroscopy platform for massively-parallel low cost binding assays.
