Published: Feb. 19, 2022

Bacterial colonization on the surface of medical implanted devices and bacterial infection-induced biofilm have been a lethal risk for patients clinical treatment. While antibacterial coatings fabricated by layer-by-layer (LBL) assembly techniques well explored, facile preparation substrate-independent smart with on-demand antibiotics release profile excellent performance is still urgently needed. In this work, goal addressed LBL fabrication robust using naturally occurring commercially available building blocks (i.e., aminoglycosides, 5,6-dihydroxyindole, formylphenylboronic acid) via subsequentially performed mussel-inspired polymerization dynamic covalent chemistries. The resulting different substates all presente feature pH-responsive), properties, highly effective both in vitro vivo. It envisioned that work can expand scope technique toward next generation universal coating materials natural readily

Fabrication of Functional Polycatechol Nanoparticles

ACS Macro Letters, Journal Year: 2022, Volume and Issue: 11(2), P. 251 - 256

Published: Jan. 24, 2022

While low-dimensional (1D and 2D) polycatechol materials have been widely described for a range of biomedical surface engineering applications, very few examples explored that focus on the construction functional nanoparticles. Herein, we report facile fabrication series nanoparticles via general robust strategy based one-step oxidation reaction. IO3--induced catechol redox chemistry could facilitate precise size control resulting also allow successful transfer amplification microscopic monomer function into macroscopic material properties. The ease, facileness, controllability such process highly promote development nanomaterials various applications.

Recent Progress on Bioinspired Antibacterial Surfaces for Biomedical Application

Biomimetics, Journal Year: 2022, Volume and Issue: 7(3), P. 88 - 88

Published: July 4, 2022

Surface bacterial fouling has become an urgent global challenge that calls for resilient solutions. Despite the effectiveness in combating invasion, antibiotics are susceptible to causing microbial antibiotic resistance threatens human health and compromises medication efficacy. In nature, many organisms have evolved a myriad of surfaces with specific physicochemical properties combat bacteria diverse environments, providing important inspirations implementing bioinspired approaches. This review highlights representative natural antibacterial discusses their corresponding mechanisms, including repelling adherent through tailoring surface wettability mechanically killing via engineering textures. Following this, we present recent progress active passive strategies. Finally, biomedical applications prospects these discussed.
