Reduction-responsive biodegradable micelles were developed from disulfide-linked dextran-b-poly(ε-caprolactone) diblock copolymer (Dex-SS-PCL) and applied for triggered release of doxorubicin (DOX) in vitro inside cells. Dex-SS-PCL was readily synthesized by thiol-disulfide exchange reaction between dextran orthopyridyl disulfide (Dex-SS-py, 6000 Da) mercapto PCL (PCL-SH, 3100 Da). Dynamic light scattering (DLS) measurements showed that yielded with an average size about 60 nm a low...

Heteroatom-doping in metal-nitrogen-carbon single-atom catalysts (SACs) is considered a powerful strategy to promote the electrocatalytic CO2 reduction reaction (CO2 RR), but origin of enhanced catalytic activity still elusive. Here, we disclose that sulfur doping induces an obvious proton-feeding effect for RR. The model SAC catalyst with second-shell FeN4 (Fe1 -NSC) was verified by X-ray absorption spectroscopy and aberration-corrected scanning transmission electron microscopy. Fe1 -NSC...
