Abstract: Certain embodiments are directed to the use of amide coupling chemistry to covalently link five different biofunctional groups onto an anionic water soluble poly(phenylene ethynylene) (PPE) polymer. Two of the biofunctionalized PPEs are used in prototype applications, including pH sensing and flow cytometry labeling.

Abstract: The inventors describe the use of a polymeric marker, in certain aspects the polymeric marker is conjugated polymeric marker such as P-C-3. Other aspects are directed to methods of analyzing the conjugated marker fluorescence spectral shape, which is strongly dependent on the local/ionic environment. This fluorescence marker is able to interact with and classify various analytes.

Abstract: Novel compounds generally referred to herein as cationic oligomeric phenylene ethynylenes (OPEs), methods of synthesizing OPEs and various uses for the OPEs are described. The compounds can be synthesized in both symmetrical (S-OPE) and non-symmetrical (N-OPE) forms. Suitable uses include sensor and biocidal applications. Reusable structures incorporating the OPEs that are able to capture and release biological species of interest are also described.

Abstract: The present disclosure provides novel polyampholyte compounds, methods for synthesizing these compounds, and materials and substances incorporating these compounds. The various polyampholytes show antibacterial activity and may also demonstrate antiviral antifungal and/or antibiofilm activity.

Abstract: A phototherapy bandage capable of providing radiation to a localized area of a patient for accelerating would healing and pain relief, photodynamic therapy, and for aesthetic applications. The phototherapy bandage may include a flexible light source that is continuous across the bandage for providing a selected light, such as a visible light, a near-infrared light, or other light, having substantially similar intensity across the bandage. The bandage may also be flexible and capable of being attached to a patient without interfering with the patient's daily routine. The phototherapy bandage may easily conform to the curves of a patient and may come in a variety of exterior shapes and sizes.

Abstract: An essentially thickness independent luminescent photoelastic coating is a single layer having a photoelastic material, a polarizing preserving luminescent dye, and an excitation absorption dye therein. The absorption dye limits a penetration depth of excitation radiation incident on the layer. The thickness of the layer is greater than a penetration depth of the excitation radiation. A strain measurement system and associated method of determining strain utilize the single layer coating.

Abstract: A method and apparatus for measuring strain on a surface of a substrate utilizes a substrate surface coated with at least one coating layer. The coating layer provides both luminescence and photoelasticity. The coating layer is illuminated with excitation light, wherein longer wavelength light is emitted having a polarization dependent upon stress or strain in the coating. At least one characteristic of the emitted light is measured, and strain (if present) on the substrate is determined from the measured characteristic.
