Abstract: The present invention relates to drug delivery devices for moist tissue, in particular mucosal tissue and tissue in the serous cavities, as well as a method of its use. The devices, which contain NOCC, are adherent to the mucosal tissue, allowing localized drug delivery. The devices are particularly useful in vaginal, buccal and ocular devices.

Abstract: A non-invasive detection method for glucose and other constituents of interest in a sample is described. The apparatus and methods of the invention provide an analog of color perception of human vision, preferably in the near infrared region, replacing the spectrophotometers used in other non-invasive near infrared detection methods. A plurality of detection units are used, each covering a broad region of the detected spectrum, paralleling color perception and colorimetry. In some circumstances, a neural net is used for analysis, allowing the system to learn. Analyte concentrations in scattering mediums can be obtained by calibrating the results with in vitro measurements.

Abstract: The present invention relates to a method of inhibiting cellular and protein attachment to substrates by applying a composition containing an effective amount of adherent N,O-carboxymethylchitosan to a substrate with such that cellular and protein attachment are prevented or greatly reduced.
