Fig. 3From: Collagen-induced assembly of adenosine monophosphate-modified gold nanoparticles for photothermal cancer therapyCharacterization of collagen-induced self-assembly of AAu NPs (CAAu). A Digital photos of AAu aqueous suspension and AAu aqueous suspension added with collagen (i.e., CAAu). B TEM images of CAAu. C The absorption spectra of AAu and CAAu. The LSPR peak shifts from 510Â nm of AAu to 515Â nm of CAAu. D Photothermal heating effects of Au, AAu and CAAuBack to article page
