Assignee:

GLUMETRICS, INC. - IRVINE CA

International Classification:

G01N 21/64

US Classification:

436172, 422 8208

Abstract:

Analyte sensors having antioxidant protection are disclosed. By combining antioxidant and/or scavenger agents into polymer matrices that contain sensor moieties, the sensor moieties are protected from reactive oxygen species. Also disclosed are methods of making analyte sensors and methods of inhibiting oxidative degradation of sensing components in hydrated, polymerized analyte sensor systems.

International Classification:

B29C 70/54

Abstract:

A system is provided that includes an adjustable surface that can be quickly adjusted through use of a plurality of actuators. The surface can be used as a dynamic decoration or a haptic visualization tool for the blind. The system uses special couplings between the actuators and the adjustable surface that allow the actuators to control the shape of the surface, while still allowing the surface to be deformed by outside pressure without forcing or damaging the actuators. These couplings formed by a selection of springs, flexures, cables, and ball joints allow the surface to be quickly adjusted to a new shape. The adjustable surface can be used to shape plastic, metal, or glass sheets or as composite layup forms. A frame of the system engages actuators in a way that allows the actuators to move in axial directions of the actuators and adjust the shape of the surface.

International Classification:

G01N 33/66

US Classification:

436 95, 521 53

Abstract:

Methods of covalently attaching heparin to a membrane comprising plasma treating the membrane to produce an amino-functionalized membrane; and reacting the amino-functionalized membrane with heparin under conditions in which heparin becomes covalently attached to the amino-functionalized membrane, wherein said heparin is indirectly attached via a spacer to said amino-functionalized membrane and/or said heparin is attached from a single site in said heparin to a single site on said amino-functionalized membrane or to said spacer. Also disclosed are analyte sensors.
