    Abstract: A photoacoustic medical imaging device may include a substrate, an array of ultrasonic transducers on the substrate, at least one groove etched on the substrate, at least one optical fiber, and at least one facet. Each optical fiber is disposed in one of the grooves. Each facet is etched in one of the grooves and coated with a layer of metal having high infrared reflectivity. Each optical fiber is configured to guide infrared light from a light source through the fiber and toward the respective facet. The facet is configured to reflect the infrared light toward a target.

    Abstract: The present invention is a system and methods of establishing a Melanocyte Protection Factor (MPF), which indicates the level of protection against DNA damage to a target cell, such as the level of protection a particular sunscreen offers against UVA rays when compared to the unprotected case, i.e., no sunscreen. The present invention determines and records levels of stable melanin radicals (SMR) in a target cell. Light is applied to the target cell forming light-induced melanin radicals (LIR). The levels of SMR and intensity of LIR are measured to determine the amount of incident light reaching the target cell. Since LIR is proportional to the square root of light intensity reaching the target cell, the ratio of light reaching the target cell is defined as the MPF (I).

    Abstract: This disclosure describes compositions and methods that involve a first modular component and a second modular component. The first modular component includes a first target molecule coupled to a first dimerizing moiety. The second modular component includes a second target molecule coupled to a second dimerizing moiety. The first dimerizing moiety dimerizes with the second dimerizing moiety when the first dimerizing moiety binds a chemical induced proximity (CIP) inducer.
