  • Lipid bilayers on nanotextured solid surfaces
    Publication number: 20080160313
    Abstract: The present disclosure provides various novel suspended planar lipid bilayer assemblies made from bicellar mixtures containing long and short chain phospholipids and methods of making the same. Such bilayer assemblies may additionally incorporate biomolecules such as proteins, polypeptides, biological complexes, transmembrane proteins and other membrane-associated compounds. The present disclosure further provides uses for such lipid bilayer assemblies including proteomics, membrane study, biosensing for medical diagnosis and environmental monitoring, chemical and biological warfare agent sequestration, actuator development, and bio-fuel cell development.

  • Sol-gel matrices for direct colorimetric detection of analytes
    Patent number: 6485987
    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.
