Tianyu Li, Wentian Xiang, Feng Li and Huaping Xu Biomaterials, 2018, 157, 17-25 It is urgently desired that self-assembly methods can be used to develop smart nanomedicines with adjustable anticancer activity and concise structure. Herein, we design carrier-free small molecule assemblies of platinum coordinated selenomethionine, which exhibit adjustable anticancer activity regulated by their self-assembly behaviors. The small molecule assemblies are prepared by coordination of selenomethionine esters with cisplatin. Their self-assembly behaviors can be tuned by esterification between sel...

Feng Li, Tianyu Li, Chenxing Sun, Jiahao Xia, Yang Jiao and Huaping Xu Angew.Chem. Int.Ed., 2017, 56, 9910–9914 Heteroatom doping is an effective way to adjust the fluorescent properties of carbon quantum dots. However, selenium-doped carbon dots have rarely been reported, eve though selenium has unique chemical properties such as redox-responsive properties owing to its special electronegativity. Herein, a facile and high-output strategy to fabricate selenium- doped carbon quantum dots (Se-CQDs) with green fluorescence (quantum yield 7.6 %) is developed through the hydro-thermal treatment...
