Abstract:
... A new fundamental concept for one-step in-situ functionalization of gold nanoparticles (GNPs) with folic acid using hydrothermal treatment is described. Hydrothermal treatment has been tuned to increase the light emission from the pterin moiety of folic acid molecule, while retain its structure and functionality, thus providing a simple route to multimodal tags for a variety of in vitro and in viv ...

MoS₂ with enlarged interlayer spacing exhibits high Mg-ion storage capacity due to the accelerated kinetics of Mg²⁺, however, continuous decay of capacity occurs during the charge/discharge process, and the exfoliation of MoS₂ monolayers is observed because of the weakened van der Waal's interaction in MoS₂ interlayers. In the present study, PVP–MoS₂ nanospheres with an interlayer spacing of 0.97 ...
