Abstract
- The unsustainable antibacterial activity of ruthenium antibacterial agents is an important factor limiting their applications. This present work attempts to prepare ruthenium (Ru) coordination polymer composites with chitosan quaternary ammonium polymers (CQ) and shikimic acid (SA) through the interaction of ionic bonds and covalent bonds by microwave-assisted high-pressure homogenization methods. The prepared CQ@Ru-SA was characterized by size distribution, zeta potential, TEM, UV-vis, FTIR, XPS and XRD analyses. The coordination structure and morphology of Bridge-CQ-NH-Ru-SA were verified. The CQ@Ru-SA was well-dispersed in both the aqueous or anhydrous states. MIC and MBC, time-killing curves, biofilm formation inhibition assay, mature biofilm disruption assay, SEM, Ca
