Microparticles decorated with cell-instructive surface chemistries actively promote wound healing

February 7, 2023

Advanced Materials Journal

Wound healing is a complex biological process involving close crosstalk between various cell types. Dysregulation in any of these processes, such as in diabetic wounds, results in chronic nonhealing wounds. Fibroblasts are a critical cell type involved in the formation of granulation tissue, essential for effective wound healing. 315 different polymer surfaces are screened to identify candidates which actively drive fibroblasts toward either pro- or antiproliferative functional phenotypes. Fibroblast-instructive chemistries are identified, which are synthesized into surfactants to fabricate easy to administer microparticles for direct application to diabetic wounds. The pro-proliferative microfluidic derived particles are able to successfully promote neovascularization, granulation tissue formation, and wound closure after a single application to the wound bed. These active novel bio-instructive microparticles show great potential as a route to reducing the burden of chronic wounds.

Complementary and Spatially Resolved Operando Spectroscopic Investigation of Pt/Al₂O₃ and Pt/CeO₂ Catalysts during CO/NO Conversion

The composition of reaction mixtures strongly influences the structural evolution and performance of noble metal-based catalysts. In this work, we compared the effect of the simultaneous presence of CO and NO on the noble metal state and CO oxidation activity of Pt/Al2O3 and Pt/CeO2 catalysts under close-to-stoichiometric conditions using complementary in situ/operando X-ray and infrared spectroscopic techniques.

Influence of the CeO₂ Morphology and Initial Pd–Pt Interaction Degree on Catalyst Activity and Stability

Due to its peculiar properties and strong interaction with noble metals, ceria is widely used as a catalyst support for numerous applications. In this work, morphologically pure and highly crystalline ceria nanocubes and nanorods were prepared to systematically investigate both the impact of the support morphology and Pd–Pt interaction degree on the noble metal-support interplay during CO oxidation.

High-throughput RAFT Polymerization via Automated Batch, Increment, and Continuous Flow Platforms

We report an automated strategy to conduct RAFT copolymerizations using a Chemspeed robotic platform capable of executing batch, incremental, and continuous monomer addition workflows under inert conditions. Copolymerizations of oligo(ethylene glycol) acrylate with benzyl acrylate (as a control) and fluorescein o-acrylate were conducted in toluene, THF, and DMF, with reaction progress monitored via ¹H NMR spectroscopy at defined intervals.
