Stimuli-Responsive Layer-by-Layer Tellurium-Containing Polymer Films for the Combination of Chemotherapy and Photodynamic Therapy

Posted on August 15, 2016May 22, 2017 by wanglu

Fuqiang Fan, Lu Wang, Feng Li, Yu Fu and Huaping Xu ACS Appl. Mater. Interfaces, 2016, 8, 17004-17010. Tellurium-containing photoresponsive polyelectrolyte multilayer films were fabricated by layer-by-layer assembly of a tellurium-containing polymer, photosensitizer, and poly(styrenesulfonate). The resulting films were investigated by UV/vis spectroscopy, XPS, EPR, and fluorescence spectroscopy. Under visible light, the photosensitizer in the film is excited and transforms triplet oxygen into singlet oxygen in aqueous solution. Singlet oxygen oxidizes −Te– to high valence state (Te═O) on...

Tellurium-Containing Polymers: Towards Biomaterials and Optoelectronic Materials

Posted on March 25, 2016May 22, 2017 by wanglu

Lu Wang, Wei Cao and Huaping Xu ChemNanoMat, 2016, 2, 479-488. Tellurium-containing polymers have been increasingly attractive owing to their unique properties as biomaterials and optoelectronic material. The relatively large atom size and low electronegativity of tellurium give tellurium many unique properties, such as coordination ability and redox sensitivity. Introducing of tellurium can endow materials different responsiveness, which makes them possible to be employed as biomaterials. The narrow band gap of polytellurophene also makes it possible to be used in optoelectronic materia...
