Abstract
The present invention relates to methods and compositions for the direct detection of analytes using color changes that occur in immobilized biopolymeric material in response to selective binding of analytes to their surface. In particular, the present invention provides methods and compositions related to the encapsulation of biopolymeric material into metal oxide glass using the sol-gel method.
Claims6
A composition comprising colorimetric diacetylene polymers encapsulated in porous sol-gel glass, wherein said colorimetric diacetylene polymers comprise one or more ligands that are capable of binding to one or more analytes, and wherein said colorimetric diacetylene polymers are capable of changing color upon the binding of said one or more analytes to said one or more ligands.
