Recent developments in antibacterial or antibiofilm compound coating for biliary stents

Fabrication of a Universal Composite Coating for Biliary Stents with Protein Antifouling and Antibacterial Synergies

“…During the process of bile sludge formation, the initial adhesion of proteins provides a nutritional environment and adhesion conditions for microorganisms such as bacteria. 1 The introduction of zwitterion polymer in the surface attempts to achieve initial protein antifouling through the formation of a strong water binding layer. The hydrophilicity of the composite coatings was evaluated by measuring the static water contact angles (WCAs).…”

“…The implantation of biliary stents into the site of stenosis or obstruction through endoscopic retrograde cholangiopancreatography (ERCP) to dilatate and allow bile flow is one of the effective methods for treating biliary obstruction. 1 However, the risk of complications after stent implantation remains a huge challenge, such as bacterial infection and stent restenosis. Once stent restenosis occurs, the current medical techniques mainly involve removing and replacing the stent, which may cause patient suffering and even surgical failure.…”

Polyelectrolyte Coatings—A Viable Approach for Cultural Heritage Protection

“…Several scientists working in stone conservation and preservation are now interested in antimcrobial and antifouling coatings [ 82 , 83 , 84 , 85 ]. The biodeteriogens, the artifact’s substance and its condition of conservation influence the cleaning method selection, however the application of chemicals (biocides) is the most popular antifouling technique.…”

Facile fabrication of robust and universal UV‐curable polyurethane composite coatings with antibacterial properties

“…Therefore, the design of effective methods to construct polyurethane coatings with antibacterial functions is of great practical significance and application value for the realization and application of functional materials, especially biomedical materials. [13][14][15][16] The main methods of antimicrobial modification of polyurethane materials are physical modification and chemical modification. Physical modification is mainly the physical blending of antimicrobial agents dispersed in polyurethane materials.…”

“…However, polyurethane materials contain a large number of polyether and polyester chain segments, which can be a carbon source for microbial growth and may cause bacterial growth under certain conditions, leading to a reduction in the service life of the material and a threat to the life and health of patients. Therefore, the design of effective methods to construct polyurethane coatings with antibacterial functions is of great practical significance and application value for the realization and application of functional materials, especially biomedical materials 13–16 …”
