 ical Sensing - Prof. Timothy M. Swager\, Department of Chemistry\, Massach
 usetts Institute of Technology

DESCRIPTION:This lecture will focus on the design of systems wherein a rec
 onfiguration of the materials can be triggered chemically or mechanically.
   The utility of these methods is to generate transduction mechanisms by w
 hich chemical and biological sensors can be developed.  Two different type
 s of systems will be discussed.  (1) Assemblies of polymers at air water i
 nterfaces and the demonstration of a luminescence strain response upon com
 pression. (2) Dynamic colloids produced from immiscible fluorocarbon/hydro
 carbon mixtures and ability to convert the core and shell layers of the dr
 oplets as well as the conversion to Janus particles.  Surfactant triggered
  changes in liquid droplets are shown in the figure below.   The latter sy
 stem’s morphology changes can also be triggered in response to chemical\
 , biological\, or optical stimuli.
