Mussel-inspired coordination functional polymer brushes-decorated rGO-stabilized silver nanoparticles composite for antibacterial application

Abstract

A catechol-terminated coordination functional polymer-modified rGO supported AgNPs composite was fabricated. Grafted polymer brushes improve the material's hydrophilicity and dispersion stability of AgNPs on rGO, enhancing antibacterial activity.

Unraveling the gallol-driven assembly mechanism of thermoreversible supramolecular hydrogels inspired by ascidians

“…6 For example, the outstanding underwater properties of marine mussel have driven a field of mussel-inspired catechol chemistry of great significance in biomaterials science and engineering. [7][8][9][10][11][12][13][14][15][16][17] Similar to mussels, ascidians are sac-like sessile marine animals that are covered with a protective membrane composed of highly crystalline cellulose nanofiber (tunicin) and proteins (tunichrome) containing 3,4,5-trihydroxyphenylalanine (TOPA) with a pyrogallol moiety (three hydroxyls bound to a benzene ring). These organisms have extraordinary biophysicochemical properties including rapid self-healing and strong adhesiveness in seawater.…”

Preparation of Lignosulfonate@AgNPs Colloidal Nanocrystal Clusters through In Situ Reduction, Confined Growth, and Self-Assembly

“…This approach can not only reduce the biotoxicity of AgNPs and the threat to the ecosystem but also improve their antimicrobial potential. For example, AgNPs have been reported to be encapsulated in PCL, PEG, − PEGMA, , and so on. Very recently, our group reported the use of a unimolecular micelle star-shaped copolymer α-CD- g -[(PEO- g -PAA)- b -PEO] to protect AgNPs and produced so-called colloidal nanocrystal clusters (Ag CNCs) which were further applied for their antibacterial activity .…”

Ag+-Adsorbing Semiconducting Polymer Nanosponge for Smart Local Treatment of Wound Infection

“…Bacterial infections has become a major threat to human health, and many patients die each year from diseases associated with infections. – Antibiotic therapy is a common treatment strategy in the fight against bacterial infections and has been widely used in clinical trials. – However, the excessive use of antibiotics could lead to antibiotic resistance in bacteria, which makes antimicrobial therapy ineffective. – Recently, light-activated photothermal therapy (PTT) shows promising potential in antibacterial therapy because they can kill bacteria cells rapidly and show remote controllability and noninvasive property. – Photothermal antimicrobial nanoagents such as CuS, – gold nanoparticles, – and molybdenum disulfide nanosheets (MoS 2 NSs) – have been developed to combat bacterial infections. However, the toxic effect of PTT nanoagents and their potential risk on environments is still a major concern .…”
