In this paper we show for the first time the suitability of gold nanorods as exogenous chromophores to mediate the near infrared laser welding of connective tissues. We used a 810 nm diode laser to simulate hetero-transplantations of patches of porcine lens capsules stained with nanorods with plasmon resonances about that wavelength. In our preliminary tests, successful welding was achieved at fluences in the 80 - 110 J·cm-2 range, which is, at worst, less than half of the threshold for direct damage, although still about a factor of two higher than the state-of-the-art with conventional chromophores such as Indocyanine Green.
