New Halogenated Flavonoids from Adenosma bracteosum and Vitex negundo and Their α-Glucosidase Inhibition.

Adenosma bracteosum and Vitex negundo are natural sources of methoxylated flavonoids. Little is known about the α-glucosidase inhibition of multi-methoxylated flavonoid derivatives. Eighteen natural flavonoids were isolated from A.

Glutathione Capped CdSe Quantum Dots: Synthesis, Characterization, Morphology, and Application as a Sensor for Toxic Metal Ions.

Glutathione (GSH) functionalized CdSe quantum dots (QDs) (GSH--CdSe QDs) were prepared via a simple one-pot strategy at low temperature. The as-synthesized CdSe QDs were characterized by FT-IR and XPS analyses. The morphology, physical structure and size distribution of GSH--CdSe QDs were investigated by TEM, XRD and DLS analyses, respectively.

Grafting of Poly(poly(ethylene glycol) methacrylate) onto Halloysite Nanotubes via Surface-Initiated Atom Transfer Radical Polymerization.

A synthetic strategy for the functionalization of halloysite nanotubes (HNTs) with poly(poly(ethylene glycol) methacrylate) (PPEGMA) via surface-initiated atom transfer radical polymerization (SIATRP). The covalent immobilization of PPEGMA was confirmed by FT-IR analysis. The preparation of the nanohybrids was further evidenced by the XPS and EDX studies.
