纳米药物载体由于具有高效的释药能力和在靶向治疗方面的广阔前景,引起了全世界的广泛关注[1-3]。然而,发展一个新型纳米载体的最大挑战在于评估纳米载体的在体内的原位药物释放。传统的技术,如正电子发射断层扫描(PET)、磁共振成像(MRI)和荧光成像,要么遭受有限的空间分辨率、复杂的贴标过程,要么难以同时跟踪纳米载体和药物,从而研究体内药物释放[4]。
An efficient quantum mechanical/molecular mechanics(QM/MM)approach is developed for investigating polymorphism-dependent emission properties of molecular crystals.
Bimetallic alloy is more effective than pure metal for controlled growth of high-quality graphene.In this work,we used the DFT-D2 method to study interfacial structure,interaction between graphene lay
The iron(Ⅲ)-iodosylbenzene complex [FeⅢ(tpena)(PhIO)]2+(1)is revealed by DFT calculat ions to chameleonically convert either to a masked hypervalent FeV–oxo species,or to a masked monomeric PhIO speci
It has been a long-standing demand to design heteronanostructures(including type-Ⅰ(straddling gap)and type-Ⅱ(staggered gap))for desired charge flow steering in semiconductor systems.
Room-temperature phosphorescent(RTP)materials have attracted an increasing number of scientific explorations because of their significant features,such as long lived excited states and higher efficien
