“…Apart from these commonly used metal nanoparticles, the antibacterial cobalt‐exchanged natural zeolite (ZEO)/PVA hydrogels were proved to possess antibacterial activity against E. coli . ZEO/PVA hydrogel with 0.48 wt% and higher cobalt‐exchanged ZEO contents showed efficient antibacterial activities against G− bacteria (i.e., E. coli and S. aureus ).…”

Antibacterial materials are recognized as important biomaterials due to their effective inhibition of bacterial infections. Hydrogels are 3D polymer networks crosslinked by either physical interactions or covalent bonds. Currently, hydrogels with an antibacterial function are a main focus in biomedical research. Many advanced antibacterial hydrogels are developed, each possessing unique qualities, namely high water swellability, high oxygen permeability, improved biocompatibility, ease of loading and releasing drugs, and structural diversity. Here, an overview of the structures, performances, mechanisms of action, loading and release behaviors, and applications of various antibacterial hydrogel formulations is provided. Furthermore, the prospects in biomedical research and clinical applications are predicted.

“…31 Apart from these commonly used metal nanoparticles, cytocompatible nickel nanoparticle-loaded chitin hydrogels were developed against S. aureus, 110 and antibacterial cobalt-exchanged natural zeolite/PVA hydrogel was proved to have antibacterial activity against E. coli. 111 Although copper-containing NPs (Cu NPs/CuO NPs) have weaker antibacterial effects than Ag NPs, they have a greater range of microbicidal activities against both fungi, especially Saccharomyces cerevisiae, and bacteria, including E. coli, S. aureus and Listeria monocytogenes. [112][113][114] CMC/ CuO nanocomposite hydrogels and CS hydrogel loaded with copper particles demonstrated excellent antibacterial effects against E. coli and S. aureus without causing any toxicity in recent studies.…”

The rapid emergence of antibiotic resistance in pathogenic microbes is becoming an imminent global public health problem. Local application of antibiotics might be a solution. In local application, materials need to act as the drug delivery system. The drug delivery system should be biodegradable and prolonged antibacterial effect should be provided to satisfy clinical demand. Hydrogel is a promising material for local antibacterial application. Hydrogel refers to a kind of biomaterial synthesized by a water-soluble natural polymer or a synthesized polymer, which turns into gel according to the change in different signals such as temperature, ionic strength, pH, ultraviolet exposure etc. Because of its high hydrophilicity, unique three-dimensional network, fine biocompatibility and cell adhesion, hydrogel is one of the suitable biomaterials for drug delivery in antimicrobial areas. In this review, studies from the past 5 years were reviewed, and several types of antimicrobial hydrogels according to different ingredients, different preparations, different antimicrobial mechanisms, different antimicrobial agents they contained and different applications, were summarized. The hydrogels loaded with metal nanoparticles as a potential method to solve antibiotic resistance were highlighted. Finally, future prospects of development and application of antimicrobial hydrogels are suggested.

Clinoptilolites have a limitation in the adsorption of drug molecules due to their fixed pore structure. In this study, we modified the clinoptilolite with benzalkonium chloride. The modification was carried out by stirring 1 g of NaCl activated clinoptilolite with 100 mL of benzalkonium chloride solution with a concentration of 0.5, 1, 5, 10 and 15 % at room temperature for 24 h. After filtration and drying process, benzalkonium chloride modified clinoptilolite was stirred with 100 mL of 300 mg/L metformin hydrochloride solution at room temperature for 24 h. The result of sample characterization using FTIR spectrometer, X-ray diffractometer and N2 Sorption analyzer showed that clinoptilolite modification with benzalkonium chloride and the impregnation of metformin hydrochloride proceeded well. The optimal amount of metformin hydrochloride occurred in benzalkonium chloride 1 % modified clinoptilolite.
