Latest Patents
Fraser's latest patents include groundbreaking inventions such as "Compositions and methods for making and using oxygen sensing nanofibers." This invention addresses the need for scaffold-based oxygen concentration monitoring by creating a single-component, self-referenced oxygen sensor in the form of nanofibers. The electrospinning process was optimized to produce a biomaterial scaffold with specific morphological features. The invention calculates the ratio of an oxygen-sensitive phosphorescence signal to an oxygen-insensitive fluorescence signal at each image pixel to determine an oxygenation value. The fibers demonstrate responsiveness to dissolved oxygen concentrations below 15 parts per million, showcasing their potential in medical applications.
Another notable patent is "Mechanochromic luminescent difluoroboron beta-diketonates." This invention provides luminescent solid-state compositions that exhibit mechanochromic luminescence, which can be stimulated by pressure. The compositions can be used for sensors and information displays in biological sensing, art, design, and consumer products. The mechanochromic effect can be reversible, allowing for innovative applications in various
