Fabrication and performance enhancement of an InO/BiVO heterojunction for -butanol gas sensing applications.

Butanol, a highly toxic volatile organic compound, poses significant health risks. Consequently, the creation of efficient gas-sensitive materials for butanol detection holds substantial practical significance. This study employed a secondary hydrothermal technique to synthesize InO, BiVO, and their composite InO/BiVO.

Smart pH-responsive polymeric micelles for programmed oral delivery of insulin.

The development of intelligent oral drug delivery carrier aiming at efficiently bring insulin to intestine is of great significance for diabetes mellitus therapy. In the present study, a series of amphiphilic pH-sensitive block copolymer poly(methyl methacrylate-co-methacrylicacid)-b-poly(2-amino ethyl methacrylate) [P(MMA-co-MAA)-b-PAEMA] was synthesized via activators regenerated by electron transfer atom transfer radical polymerization (ARGET ATRP) and further self-assembled into pH-responsive cationic polymeric micelles (PCPMs) for oral insulin delivery. The structure and molecular weight were confirmed by proton nuclear magnetic resonance (H-NMR), Fourier transforming infrared spectrum (FT-IR) and gel permeation chromatography (GPC), respectively.
