摘      要：Currently,the combination of photothermal therapy（PTT） and photodynamic therapy（PDT） has emerged as a powerful technique for cancer ***,most examples of combined PTT and PDT reported use multi-component nanocomposites under excitation of separate wavelength,resulting in complex treatment *** this work,a novel theranostic nanoplatform（SiNcOH-DSPE-PEG（NH2）NPs） has been successfully developed by coating silicon 2,3-naphthalocyanine dihydroxide（SiNcOH）with DSPE-PEG and DSPE-PEG-NH2 for photoacoustic（PA） imaging-guided PTT and PDT tumor ablation for the first *** as-prepared single-agent SiNcOH-DSPE-PEG（NH2） NPs not only have good water solubility and biocompatibility,but also exhibit high photothermal conversion efficiency and singlet oxygen generation capability upon 808 nm NIR laser *** addition,owing to their high absorption at NIR region,the SiNcOH-DSPE-PEG（NH2） NPs can also be employed as an effective diagnostic nanoagent for photoacoustic（PA） *** vitro and in vivo experimental results clearly indicated that the simultaneously combined PTT and PDT under the guidance of PA imaging with single NIR laser excitation can effectively kill cancer cells or eradicate tumor *** facile synthesis and high efficiency in cancer treatment by SiNcOH-DSPE-PEG（NH2） NPs into consideration,our study provides a promising strategy to realize molecular imaging-guided combination therapy.
