title: Surfactant-Stripped Frozen Pheophytin Micelles for Multimodal Gut Imaging.
abstract: Edible, surfactant-stripped, frozen micelles are formed from pheophytin (demetallated chlorophyll), a pigment that is naturally consumed in human diets. Pheophytin nanoparticles pass completely and safely through the gastrointestinal tract and enable trimodal gut contrast imaging via photoacoustic, fluorescence, and positron emission tomography techniques.
