A study on the antibacterial activity and antimicrobial resistance of pyridinium cationic pillar[5]arene against Staphylococcus aureus and Escherichia coli.

An increasing number of infections caused by multidrug-resistant (MDR) Staphylococcus aureus （S. aureus） and Escherichia coli （E. coli） have severely affected human society.

Biosynthesis of chitosan-coated iron oxide (FeO) hybrid nanocomposites from leaf extracts of L. and study on their antibacterial potentials.

In this study, we prepared chitosan (CS)-coated iron oxide (FeO) nanocomposites (NCs) by employing the aqueous leaf extract of L. and evaluated its antimicrobial potential. The characterization of hybrid CS-FeO NCs was performed using Fourier-transform infrared spectroscopy (FTIR) analysis to evaluate the chemical bonding of chitosan to nanoparticles (NPs).

Antibacterial and Antibiofilm Formation Activities of Pyridinium-Based Cationic Pillar[5]arene Against .

An omnipresent pathogenic bacterium, ( PAO1), is easy to contaminate environmental water or foods, causing daily food spoilage and infections. The biofilm-forming ability and bacterial resistance of PAO1 make it difficult to be eradicated by traditional bacteriostatic agents. In this work, we designed and synthesized a pyridinium-based pillar[5]arene (PP5), while trimethylammonium-based pillar[5]arene (TP5) was used as a control compound.
