Mercaptopropionic acid (MPA) capped Au nanoclusters displayed higher cellular internalization compared to glutathione (GSH) capped Au nanoclusters and resulted in significantly higher intracellular reactive oxygen species level with increasing surface bound MPA ligands. The altered redox signaling resulted in augmented cell metabolism and proliferation.

A general route has been developed for the direct synthesis of N-doped bilayer graphene on Si3N4/SiC substrates. Using a nitrogen atmosphere during the growth, the formation of a graphene/Si3N4 heterostructure is possible in a one-step process.

The size of gold and silica nanospheres determines their inhibitory effects on vascular endothelial growth factor (VEGF)-mediated angiogenesis. In this study, 20 nm size gold and silica nanospheres suppress VEGF-induced activation of VEGF receptor-2, in vitro angiogenesis, and in vivo pathological angiogenesis more efficiently than their 100 nm size counterparts.

Single- and multilayer phosphorene have been prepared by mechanical exfoliation followed by plasma thinning. Optical contrast spectra combined with atomic force microscopy is used to identify the thickness. The thickness-dependent Raman spectra are also presented.

Piezo-modulated interface engineering to enhance the photoresponse of all-oxide Cu2O/ZnO heterojunction has been reported for the first time. Under illumination at a power density of 17.2 mW/cm2, a photoresponse increase of 18.6% was obtained when applying a –0.88% compressive strain.

A polymer-coated graphene micro-tube piping (GMP) structure with a cross-linked and interconnected channel network has been synthesized. The GMP can be used as a sensor for volatile organic compounds in liquid solution with good selectivity, high sensitivity, and rapid response.

Steric hindrance leads to a strongly modified chirality in square planar coordination of Fe(TCNB)4 (TCNB = 1,2,4,5-tetracyanobenzene) complexes upon organometallic self-assembly on surfaces. The competition between steric and electronic effects is found to be due to growth-induced confinement.
