In vivo cancer marker detection using surface enhanced Raman with scFv-antibody conjugated gold nanoparticles that recognize the tumor marker. (a) SERS spectra obtained from the tumor (red) and liver (blue) by using targeted nanoparticles and (b) non-targeted nanoparticles. (c) Photographs showing a laser beam focusing on tumor or liver sites. In vivo SERS spectra were obtained with a 785 nm laser at 20 mW and 2 sec integration.
