| 1 | In Vivo Tumor-Targeted Dual-Modality PET/Optical Imaging with a Yolk/Shell-Structured Silica Nanosystem显示文摘Silica nanoparticles have been one of the most promising nanosystems for biomedical applications due to their facile surface chemistry and non-toxic nature. However, it is still challenging to effectively deliver them into tumor sites and noninvasively visualize their in vivo biodistribution with excellent sensitivity and accuracy for effective cancer diagnosis. In this study, we design a yolk/shell-structured silica nanosystem ^(64) Cu-NOTAQD@HMSN-PEG-TRC105, which can be employed for tumor vasculature targeting and dual-modality PET/optical imaging, leading to superior targeting specificity, excellentimaging capability and more reliable diagnostic outcomes.By combining vasculature targeting, pH-sensitive drug delivery, and dual-modality imaging into a single platform,as-designed yolk/shell-structured silica nanosystems may be employed for the future image-guided tumor-targeted drug delivery, to further enable cancer theranostics. | Sixiang Shi Feng Chen Shreya Goel Stephen A.Graves Haiming Luo Charles P.Theuer Jonathan W.Engle Weibo Cai | 2018 | Nano-Micro Letters2018，10，4： | 2 |
| 2 | Engineering biocompatible TeSex nano-alloys as a versatile theranostic nanoplatform显示文摘Photothermal nanotheranostics, especially in the near infrared II(NIR-II) region, exhibits a great potential in precision and personalized medicine, owing to high tissue penetration of NIR-II light.NIR-II-photothermal nanoplatforms with high biocompatibility as well as high photothermal effect are urgently needed but rarely reported so far. Te nanomaterials possess high absorbance to NIR-II light but also exhibit high cytotoxicity, impeding their biomedical applications. In this work, the controllable incorporation of biocompatible Se into the lattice of Te nanostructures is proposed to intrinsically tune their inherent cytotoxicity and enhance their biocompatibility, developing TeSe_(x) nano-alloys as a new kind of theranostic nanoplatform. We have uncovered that the cytotoxicity of Te nanomaterials primarily derives from irreversible oxidation stress and intracellular imbalance of organization and energy, and can be eliminated by incorporating a moderate proportion of Se(x = 0.43). We have also discovered that the as-prepared TeSe_(x) nano-alloys have extraordinarily high NIR-II-photothermal conversion efficiency(77.2%),^(64)Cu coordination and computed tomography contrast capabilities, enabling high-efficacy multimodal photothermal/photoacoustic/positron emission tomography/computed tomography imaging-guided NIR-II-photothermal therapy of cancer. The proposed nano-alloying strategy provides a new route to improve the biocompatibility of biomedical nanoplatforms and endow them with versatile theranostic functions. | Xiang Ling Zhaokui Jin Qi Jiang Xiaotao Wang Bin Wei Zhongchang Wang Yangsen Xu Tianye Cao Jonathan W.Engle Weibo Cai Chenliang Su Qianjun He | 2021 | National Science Review2021，8，6： | 0 |
