DOI: 10.1364/ome.9.004532
Abstract: Phase change nanoemulsions have been proposed as theranostic agents, using light to induce vaporization into bubbles (also called optical droplet vaporization). The current work uses perfluorohexane nanoemulsions (PFH-NEs) stabilized by a highly biocompatible and optically… read more here.
