In particular, embodiments of thermal treatment of acne with coated metal nanoparticles are disclosed.
Claims1
A method for performing thermoablation, comprising the steps of contacting a target tissue region of a mammalian subject with a composition comprising a plurality of plasmonic nanoparticles under conditions such that an effective amount of the plasmonic nanoparticles localize to a domain of the target tissue region;
- and exposing the target tissue region to energy delivered from a nonlinear excitation surface plasmon resonance source in an amount effective to induce thermoablation of the domain of the target tissue region, wherein the nanoparticle comprises an optical absorption of about 200 nm to about 10,000 nm.
