Abstract: This invention provides protein or polypeptide imprinted polymers with integrated emission sites (PIPIES) for detecting the presence of a protein or polypeptide analyte comprising templated sites which are specific for the analyte. At or near the templated sites are selectively placed reporter molecules. A method is also disclosed for the preparation of the PIPIES and the use of these for the detection of analytes.

Abstract: The present invention provides a method and a device for high-throughput, simultaneous, and continuous detection of one or more analytes using a pin-printed chemical sensor array. Chemical sensors comprising [Ru(4,7-diphenyl-1,10-phenanthroline)3]2+, glucose oxidase, and fluorescein sequestered in sol-gel-derived-glass have been used. Examples of analytes detected using the present method include O2, glucose, and protons. Gas-phase and liquid-phase analytes have been detected using the present method. In addition, analytes contained in an aerosol have been detected.

Abstract: Provided is a non-invasive method for identification of non-physiological, physiological or diseased states based on the volatiles in gas or biogas samples from individuals. The method uses a sensor array comprising a plurality of distinct sensors which differ from other sensors by the sensing molecules or the sol-gel holding material composition. In response to a combination of volatiles, a pattern of responses is generated which can be correlated to particular non-physiological, physiological or diseased state.

Abstract: The present invention provides a reepithelialization/wound healing implant device comprising a barrier layer and one or more polymer layers doped with agents that promote one or more processes in reepithelialization/wound healing. The implant: [a] provides a temporary mechanical/chemical barrier to species within the external environment that inhibit epithelial migration (e.g., unbalanced production/expression of granulation tissue, inhibitory proteins); [b] biodegrades at an appropriate rate while tissue remodeling is occurring; and [c] delivers active cytokines and growth factors in a choreographed pattern to promote reepithelialization.

Abstract: The present invention relates to a coating composition including a sol-gel matrix and a dendrimeric organochalcogeno derivative and a system including the coating composition and a substrate. The present invention also relates to a method of preventing fouling of surfaces subjected to a marine environment.

Abstract: A new method to rapidly produce and screen polymer-, xerogel-, bioceramic- and bioglass-based formulations is described. The approach is based on a high-speed pin printer and imaging with an epi-fluorescence microscope/charge coupled device detector. By using this method one can produce and screen over 600 formulations/hr and rapidly identify lead formulations and/or compositions that are useful for the development of devices such as medical devices and (bio)sensors.

Abstract: A sensing system for quantifying a gaseous species or an analyte in a sample in accordance with one embodiment of the present invention includes a light emitting diode and a detector. The light emitting diode is coupled to a power source and at least a portion of the light emitting diode is coated with a sol-gel-derived film doped with a doping material. The detector is spaced from and substantially across from the portion of the light emitting diode coated with the sol-gel-derived film. The system may include a filter which is located between the light emitting diode and the detector and a processing system which is coupled to the detector for quantifying the amount of a gaseous species or an analyte in a sample based on data from the detector.

Abstract: A sensor having a substrate overlayed with a sol-gel layer, a chemical sensing species deposited upon the sol-gel layer, and a thin film of a second sol-gel layer overlaying and entrapping the species. The effect of this sensor is that the species exhibits a significant portion of its intrinsic function over a period of time. In yet another embodiment of the subject invention, a method is disclosed to form a thin sol-gel layer upon an ambient substrat. This method ensures the integrity, stability and functionality of the chemical sensing species within the sol-gel layers.
