Surfactant-Stripped Frozen Pheophytin Micelles for Multimodal Gut Imaging

Adv Mater. 2016 Oct;28(38):8524-8530. doi: 10.1002/adma.201602373. Epub 2016 Jul 11.

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.

Keywords: chlorophyll; frozen micelles; gut imaging; multimodal imaging; pheophytin.
