The NIR emission wavelength is adapted to excite the nanoparticles to melt fat within the target area so that the liquefied fat can be aspirated from the target area. The nanoparticles may be gold nanorods having aspect ratios selected to produce surface plasmon resonance when irradiated with NIR light around 800 nm. o\ o\ FIG. 1 i-H o CJ o & INTO 7A36FT ARFA TO ASPIRATE: L!QUEF!£D FAT m WO 2013/169955 Al I lllll llllllll II llllll III lllll lllll III III III lllll lllll lllll lllll lllll llll llll lllllll llll llll EE, ES, FI, FR, GB, GR, HR, HU, IE, IS, IT, LT, LU, LV, MC, MK, MT, NL, NO, PL, PT, RO, RS, SE, SI, SK, SM, TR), OAPI (BF, BJ, CF, CG, CI, CM, GA, GN, GQ, GW, ML, MR, NE, SN, TD, TG).
