【Abstract】 Chemistry and biology properties of selenium nanoparticle(nanoSe0) derive from its interfacial characterization.The interfacial chemistry properties of nanoSe0,for example,the interface structure,interface electronic structure and electron transfer between nanoSe0 and surface modifiers(surf) as well as the interface chemical reaction between nanoSe0-surf and ions,molecules or other objects,are closely related to its excellent function in materials science and biological science.Therefore,interface characteristics of the nanoSe0 would be investigated.The major objective of this study is to reveal the interface structure-activity relationship of the nanoSe0 system in biological activity and biomineralization.更多还原
