1. A system for selective removal of fat in a subject in need thereof, comprising:

  • a solution comprising gold nanorods suspended in a biocompatible liquid at a concentration range of 1011 to 1013 GNR/mL;

    an injector configured for distributing the solution within a target area comprising adipose tissue located beneath a skin surface;

    a light source configured for delivering a series of pulses of near infrared light across the skin surface and into the target area for an exposure duration to induce surface plasmon resonance in the nanoparticles, wherein the near infrared light has a combination of optical parameters selected from the group consisting of beam energy, pulse duration, emission wavelength within a range of 700 to 900 nm, emission intensity, beam focus and beam area, the optical parameters and the exposure duration selected to excite the nanoparticles to liquefy fat within the target area.
