Patent number: 8114348Abstract: A screening system and method are described herein which provide a unique and practical solution for enabling label-free high throughput screening (HTS) to aid in the discovery of new drugs. In one embodiment, the screening system enables direct binding assays to be performed in which a biomolecular interaction of a chemical compound (drug candidate) with a biomolecule (therapeutic target) can be detected using assay volumes and concentrations that are compatible with the current practices of HTS in the pharmaceutical industry. The screening system also enables the detection of bio-chemical interactions that occur in the wells of a microplate which incorporates biosensors and surface chemistry to immobilize the therapeutic target at the surface of the biosensors. The screening system also includes fluid handling and plate handling devices to help perform automated HTS assays.Type: GrantFiled: June 9, 2009Date of Patent: February 14, 2012Assignee: Corning IncorporatedInventors: Stephen J.

Patent number: 7871811Abstract: The present invention includes several methods for modifying the current processes of manufacturing optical sensing microplates that use continuous waveguide films to reduce/eliminate crosstalk between the biosensors that are incorporated within wells. The methods include (1) physically deteriorating/removing the waveguide film between individual biosensors; (2) chemically depositing highly absorbing materials within the waveguide film between individual biosensors; (3) patterning disordered (scattering) regions between the diffraction gratings that define individual biosensors; (4) using a specific mask and depositing individual patches of waveguide film, where each patch defines at least one biosensor. Each of these methods and several other methods described herein prevent the propagation of light between individual sensing regions, thereby eliminating optical crosstalk between the biosensors. The present invention also includes the resulting microplate.Type: GrantFiled: April 7, 2005Date of Patent: January 18, 2011Assignee: Corning IncorporatedInventors: Ye Fang, Ann M. Ferrie, Norman H.

Patent number: 6770291Abstract: Highly efficient cationic liposomes have been developed as an improved delivery system for biologically-active reagents. A novel structure, the sandwich liposome, is formed and comprises one or more biologically active agents internalized between two bilomellar liposomes. This structure protects the incoming agent and accounts for the high efficiency of in vivo delivery and for the broad tissue distribution of the sandwich liposome complexes. These novel liposomes are also highly efficient carriers of nucleic acids. By using extruded DOTAP:cholesterol liposomes to form complexes with DNA encoding specific proteins, expression has been improved dramatically. Highest expression was achieved in the lung, while increased expression was detected in several organs and tissues.Type: GrantFiled: November 20, 2001Date of Patent: August 3, 2004Assignee: The United States of America as represented by the Department of Health and Human ServicesInventors: Nancy Smyth-Templeton, George N.
