Foldable Polymers as Gene Probes


This technology utilizes novel probes to detect and identify target biomolecules in a sample. These probes employ conformational changes induced by molecular recognition events to initiate changes in the optical properties of the probe (e.g. the modulation of a fluorescence or absorption response upon target binding). Methods, including solid phase synthesis techniques for making probe molecules have been developed.

Applications and Advantages

§  Versatile approach to molecular recognition

§  Hairpin formation not a prerequisite for self association

§  Optical response can be tailored to application

§  Multiple targets can be probed simultaneously

§  Both the composition and nature of the probes and reporters can be modulated
