DOI: 10.1007/s12104-019-09904-y

Abstract: β-Phosphoglucomutase (βPGM) is a magnesium-dependent phosphoryl transfer enzyme that catalyses the reversible isomerisation of β-glucose 1-phosphate and glucose 6-phosphate, via two phosphoryl transfer steps and a β-glucose 1,6-bisphosphate intermediate. Substrate-free βPGM is an essential component… read more here.

DOI: 10.1039/c6nr09896g

Abstract: Heterostructures of one-dimensional nanowire supported graphene/plasmonic nanoparticles are promising for future SERS-based chemical sensors. In this paper, we report a novel heterostructured SERS substrate composed of free-standing Si nanowires and surface-decorating Au/graphene nanoparticles. We successfully… read more here.

DOI: 10.1039/c8cc09688k

Abstract: We develop a substrate-free and label-free electrocatalysis-assisted biosensor for sensitive detection of microRNA using the iron-embedded nitrogen-rich carbon nanotubes (FeCN) as the catalytic elements. This biosensor exhibits excellent selectivity and high sensitivity with a detection… read more here.
