• coating on polymer substrates, typically polylactide films. Interfacial adhesion of graphene-based nanosheets on polylactide substrates made the antibacterial coating stable for several application purposes. In general, supramolecular graphene-based hydrogels are bioinspired hydration structures to

The

• the GO-SG-ZH hydrogel on PLA films produced an antibacterial coating on the substrate. Antibacterial tests of uncoated and coated PLA films are described in Figure 10, where the interfaces between PLA films and agar/E. coli plates are displayed. Before the incubation process, E. coli bacteria did not

• antibacterial balloon catheters and ureteral stents. The antibacterial coating of these stents should not only prevent the ascend of bacteria into the renal pelvis, but also the formation of encrustations. Bacteria, especially proteus mirabilis, release urease, an enzyme that is capable to hydrolyze urea into

• contact to the urethra, the antibacterial coating must be applied not only to the interior wall of the capillary but to the exterior wall as well. It is evident that fabrication of an even thickness along the interior wall of a closed-end pipe with an aspect ratio of up to 1:100 (diameter/length) is a

In this paper, the most important steps of the fabrication of urethral catheters with an antibacterial coating are addressed and described
