Infections with spp. are commonly found in long-time denture wearers, and when under immunosuppression can lead to stomatitis. Imidazolium ionic liquids with an alkyl or alkyloxymethyl chain and a natural (1,2,5)-(-)-menthol substituent possess high antifungal and antiadhesive properties towards , , and . We tested three compounds and found they disturbed fungal plasma membranes, with no significant hemolytic properties. In the smallest hemolytic concentrations, all compounds inhibited biofilm formation on acrylic, and partially on porcelain and alloy dentures. Biofilm eradication may result from hyphae inhibition (for alkyl derivatives) or cell wall lysis and reduction of adhesins level (for alkyloxymethyl derivative). Thus, we propose the compounds presented herein as potential anti-fungal denture cleaners or denture fixatives, especially due to their low toxicity towards mammalian erythrocytes after short-term exposure.

Hydrogel membranes can offer a cutting-edge solution for abdominal hernia treatment. By combining favorable mechanical parameters, tissue integration, and the potential for targeted drug delivery, hydrogels are a promising alternative therapeutic option. The current review examines the application of hydrogel materials composed of synthetic and biological polymers, such as polyethylene glycol (PEG), polyvinyl alcohol (PVA), gelatine, and silk fibroin, in the context of hernia repair.

Postsurgical adhesions are a common complication associated with surgical procedures; they not only impact the patient's well-being but also impose a financial burden due to medical expenses required for reoperative surgeries or adhesiolysis. Adhesions can range from a filmy, fibrinous, or fibrous vascular band to a cohesive attachment, and they can form in diverse anatomical locations such as the peritoneum, pericardium, endometrium, tendons, synovium, and epidural and pleural spaces. Numerous strategies have been explored to minimize the occurrence of postsurgical adhesions.

Compared to antimicrobial agents, anti-adhesive surfaces can reduce bacteria adhesion and biofilm formation in catheters, providing better selectivity, efficiency, and device life span. In this research, novel anionic surface biomaterials were created and tested to reduce microbial adhesion and colonization in medical device coating. Maleic anhydride (MA) was polymerized with 2-HEMA in varying amounts to produce a p(HEMA--MA) hydrogel copolymer.

Oil-water separation materials with specialized wettability have garnered significant attention in the field of oil-water separation due to the advantages of simple use and no secondary pollution. However, the adsorptive contamination of the filter surface by impurity phases and surfactants can cause a shift in the wettability of the filter surface. For efficient oil-water separation and improved resistance to adherent contamination on the oil-water separation membrane surface, herein, superwetted Cu nanofilms and smooth hydrophobic surfaces were prepared on SSM substrates by one-step electrodeposition and immersion methods, respectively.

Antiadhesive coatings have been extensively studied owing to their wide applications in biology, environment, and energy. However, developing a mechanically robust coating with broad-spectrum antiadhesion properties remains challenging. Herein, a novel strategy for preparing hard yet flexible and self-adaptive zwitterionic polysilazane coatings with broad-spectrum antiadhesion properties (anti-biofouling, anti-liquid adhesion, and anti-scaling) is proposed.
