DESCRIPTION:Optical resonators provide one of the most accurate rulers kno
 wn to mankind. My team explores the translation of this capability to biom
 edical applications\, i.e. studies of cells and animal models. In one exam
 ple\, we use ultra-soft elastic Fabry-Perot micro-resonators as substrates
  for cells and interferometrically detect the forces cells apply to these 
 – with piconewton precision and at video-rate speed. This has enabled di
 rect observation of biophysical processes relevant to cancer invasion\, im
 mune cell migration\, kidney failure\, cardiac contraction and others. In 
 another example\, we implant nanolasers into live cells and propose dense 
 spectral multiplexing of multiple lasers to track individual cells within 
 large cell populations and over extended periods of time. We recently exte
 nded this to in vivo sensing\, e.g. to measure contractility in the beatin
 g heart. Finally\, using micro-cavity OLEDs\, we explore the possibilities
  of a bi-directional optical interface to cells\, e.g. controlling and rec
 ording the activity of neurons in the brain with a minimally-invasive impl
 ant.
