DESCRIPTION:Title: <a href="https://researchseminars.org/talk/SENSEnano/3/
 ">Dynamic lens systems for biosensing</a>\nby Tim Swager (John D. McArthur
  Professor\, Chemistry) as part of SENSE.nano Symposium from MIT.nano\n\n\
 nAbstract\nThis talk will focus on the design of systems wherein reconfigu
 ration of complex liquid emulsions (droplets) can be triggered chemically 
 or biochemically. The utility of these methods is to generate new transduc
 tion mechanisms by which chemical and biological sensors can be developed.
  Complex liquid droplets behave as optical lens systems and small changes 
 in surface tensions can change focal lengths or cause systems to switch be
 tween optically transmissive or scattering states. Central to this scheme 
 is that the fluids in the droplets have different densities and hence are 
 aligned by the earth’s gravity. The induced optical changes can be trigg
 ered with chemical\, photochemical\, or biochemical stimuli and thereby cr
 eate new generations of sensors. Demonstrations of these methods for the d
 etection of proteins\, antibodies\, and pathogens will be presented.\n
