Nevertheless, drug release modes were randomly depending on the pH changes of tumor cells. Some NPs against colon tumor through PTT effect had been designed. Gold nanocluster-loaded hybrid albumin nanoparticles were developed for colon tumor ablation [27]. Recently, gold nanorods were designed and ...
Gold nanoparticles (GNP) is synthesized through an improved citrate-reduction method, which was used to illustrate the photo-thermal conversion of PNPs under a solar simulator with eight filters. Experimental results showed that the best light intensities at wavelength of 710 nm could reach 0.004 W...
