Analyte Sensing Platform

ChromaTwist molecules are aromatic organic materials comprising of donor and acceptor groups, enabling the creation of fluorescent probes for sensing applications.

ChromaTwist fluorophores:

  • Undergo fluorescence quenching in the presence of electron deficient aromatics
  • Undergo fluorescent modulation upon binding metal cations in an appended crown ether moiety
  • Undergo fluorescence shifts upon modulation of the subphase pH
