(a) Preparation of the perfluorocarbon (PFC)-loaded microbullets (MBs): (left) nanofabricated MB, the (middle) conjugation of thiolated cysteamine to the inner Au layer of the MB, (right) electrostatic binding of the anionic PFC emulsion to the cysteamine functionalized surface. Insets show magnified views of (left) cysteamine and (right) cysteamine electrostastically bound to PFC respectively. (b) Schematic portrayal of microbullet propulsion via acoustic droplet vaporization of the bound PFCs triggered by an ultrasound pulse.
