Abstract
Growth factors play a vital role in wound healing, and novel hydrogel carriers suitable for growth factors have always been a research hotspot in the wound healthcare field. In this work, a wound microenvironment-responsive hydrogel drug-loading system was constructed by cross-linking of the internal electron-deficient polyester and bovine serum albumin (BSA) via catalyst-free amino-yne bioconjugation. The slightly acidic microenvironment of wound tissues induces the charge removal of BSA chains, thus releasing the basic fibroblast growth factor (bFGF) loaded through electrostatic action. Besides, the BSA chains in the gel network further endow their excellent biocompatibility and biodegradability, also making them more suitable for bFGF loading. The wound caring evaluation of the hydrogel in the full-thickness skin wound indicated that the protein-based hydrogel significantly promotes the proliferation and differentiation of fibroblasts, collagen accumulation, and epidermal layer stacking, thus significantly shortening the healing process. This strategy paved the way for broadening the application of the growth factors in the wound care field.

Abstract
Lanthanide nanoprobes have attracted extensive attention for applications in cellular imaging and biological sensing. Herein, water-dispersible europium (III)-based (Eu(III)-based) nanoprobes were prepared by reversible addition-fragmentation chain transfer (RAFT) polymerization-induced self-assembly (PISA) of hydrophobic monomers (Eu(III)-containing monomer and methyl methacrylate (MMA)) using hydrophilic macro-chain transfer agent poly(PEGMA)-CTA. The resulted poly(PMEu) nanoprobes showed spherical in shape in good monodispersity with average diameters of around 210 nm. The poly(PMEu) nanoprobles excellent aqueous dispersity, high aqueous stability and good luminescence properties with quantum yields of 37.21% and fluorescence lifetime of 312.4 μs. Moreover, the poly(PMEu) nanoprobes exhibited good cellular biocompatibility with cell viabilities of 88.2% and high fluorescence intensity for in vitro cellular imaging. The present approach provides a facile strategy for fabrication of luminescent Eu(III)-based nanoprobes with great potential applications for biological imaging.

Abstract
The hydrothiolation of activated alkynes is presented as an attractive and powerful way to functionalize thiols bearing catechols. The reaction was promoted by a heterogeneous catalyst composed of copper nanoparticles supported on TiO2 (CuNPs/TiO2) in 1,2-dichloroethane (1,2-DCE) under heating at 80 °C. The catalyst could be recovered and reused in three consecutive cycles, showing a slight decrease in its catalytic activity. Thiol derivatives bearing catechol moieties, obtained through a versatile Michael addition, were reacted with different activated alkynes, such as methyl propiolate, propiolic acid, propiolamide or 2-ethynylpyridine. The reaction was shown to be regio- and stereoselective towards anti-Markovnikov Z-vinyl sulfide in most cases studied. Finally, some catechol derivatives obtained were tested as ligands in the preparation of coordination polymer nanoparticles (CNPs), by taking the advantage of their different coordination sites with metals such as iron and cobalt. An attractive approach to the synthesis of catechol derivates through thiol-yne click reaction is presented. Compounds obtained were used in the preparation of CNPs.![]()
