Fig. 3From: Gold nanoparticles as multimodality imaging agents for brain gliomasOptical images of entire brain with MUA-AuNPs. Optical images of the entire brain reveal tumor cells with fluorescent MUA-AuNPs. The images on the left-hand side were taken under normal illumination and show no fluorescence. The right-hand images were taken under UV light exposure and reveal the nanoparticle fluorescenceBack to article page
