Insights into Shape-Based Silver Nanoparticles: A Weapon to Cope with Pathogenic Attacks

“…118,279−281 The cationic polymer-modified reduced graphene oxide (rGO)−AgNP complex inhibited S. aureus and E. coli growth accompanied by cell membrane damage and ROS generation mechanism. 282 In both in vitro and in vivo studies, it was observed that the 283 This result reveals the synergetic effect of AgNPs and chitosan against S. aureus. However, in another study, contradictory results were obtained upon treatment with the same composites.…”

“…Polymers such as chitosan, graphene, cellulose, polylactic acid, and other metals such as gold (Au) and titanium (Ti) have been utilized as composites to make composite–AgNP complexes that offer more power to the AgNPs than human pathogens. ,− The cationic polymer-modified reduced graphene oxide (rGO)–AgNP complex inhibited S. aureus and E. coli growth accompanied by cell membrane damage and ROS generation mechanism . In both in vitro and in vivo studies, it was observed that the biopolymer chitosan–AgNPs composite inhibited the growth of MRSA.…”

Synthetic Antimicrobial Polymers in Combination Therapy: Tackling Antibiotic Resistance

“…Very recently, Zhou et al have developed novel hybrid nanomaterials composed of polymer-modified reduced graphene oxide nanosheets and AgNPs with promising antimicrobial activity. 160 Catechol-terminated hydrophilic quaternized polymer (qCP) was prepared via RAFT polymerization of DMAEMA and subsequent quaternization of tertiary amines using benzyl chloride. The resulting polymer was then grafted onto the reduced GO nanosheets (rGO) via mussel-inspired modification strategy to obtain qCP-modified rGO (rGO− qCP).…”

Construction of polymer brush-decorated amphiphilic Janus graphene oxide nanosheets via a Pickering emulsion template for catalytic applications

“…1a and d) are similar to the C 1s spectra of GO, but the intensity of the peaks of the oxygen-containing functional groups is significantly reduced, while the C-C characteristic peaks dominate, this also indicates that most of the GO underwent a reduction in subsequent reactions such as polymer chain modification and loading of Pd NPs. The N 1s peaks with binding energies of 399.6 eV (-NH-) and 402.6 eV (-N + ) correspond to the amide bond on the polymer PNIPAM and the quaternary ammonium salt cation on the polymer P(VBTAC-co-St) segment, 46 indicating that the two polymer chains are grafted onto the surface of GO via p-p Fig. 1 XPS spectra of C 1s, N 1s, and Pd 3d peaks of PNIPAM-GO-P(VBTAC-co-St)@Pd (a-c) and PSt-GO-P(NIPAM-co-MQ)@Pd (d-f).…”
