Abstract: Biologically-inspired compositions, including color changing compositions, and corresponding embodiments such as sensors, textile materials, coatings and films, are provided which typically include a solid, transparent and nondegradable matrix. The matrix contains a plurality of (i) synthetic particles having a size in the micrometer or nanometer range, each synthetic particle including one or more aggregates of a pigment selected from phenoxazone, phenoxazine, and a derivate or precursor thereof, and a stabilizing material which has a refractive index larger than 1.45, the aggregates having a size larger than about 100 nm; or (ii) submicrometer natural particles extracted and purified from homogenized tissue.

Abstract: Cosmetic and dermatological compositions, including color changing compositions, are provided which typically include a plurality of synthetic particles having a size in the micrometer or nanometer range. Each synthetic particle typically includes one or more aggregates of a pigment selected from phenoxazone, phenoxazine, and a derivate or precursor thereof, and a stabilizing material which has a refractive index larger than 1.45; the aggregates having a size larger than about 100 nm and the composition being biodegradable and biocompatible.
