Catheter associated urinary tract infection (CAUTI) is the most frequent healthcare associated infection, arising from microbial adhesion to catheter surfaces, biofilm development, and the growing problem of antimicrobial resistance. Many publications have addressed CAUTI epidemiology, biofilm biology, or biomaterials for catheters in isolation, yet there is little literature that connects these areas into a coherent translational perspective. This review seeks to fill that gap by combining an overview of biofilm pathophysiology with recent advances in material based innovations for catheter design, including nanostructured and responsive coatings, sensor enabled systems, additive manufacturing, and three dimensional printing.

Glycosaminoglycan-based biohybrid hydrogels represent a powerful class of cell-instructive materials with proven potential in tissue engineering and regenerative medicine. Their biomedical functionality relies on a nanoscale polymer network that standard microscopy techniques cannot resolve. Here, we introduce an advanced analytical approach that integrates transmission electron microscopy, X-ray scattering, and computer simulations to directly and quantitatively characterize the nanoscale molecular network structure of these hydrogels.

Coordination polymers (CPs) are versatile materials formed by metal ions and organic ligands, offering a broad range of structural and functional possibilities. Phosphonates and phosphinates are particularly attractive ligands for CPs due to their multiple binding sites, varied coordination geometries, and ability to form robust network structures. Phosphonates, considered harder ligands, form strong bonds with hard metals such as Fe, while phosphinates offer additional versatility due to the varied pendant groups on phosphorus.

Diabetic wounds present persistent challenges due to impaired healing, recurrent infection, oxidative stress, and dysregulated glucose metabolism. Bioinspired polymeric microneedle (MN) patches have emerged as multifunctional platforms capable of penetrating the stratum corneum to deliver therapeutics directly into the dermis, enabling glucose regulation, antimicrobial action, reactive oxygen species (ROS) modulation, and proangiogenic stimulation. Recent experimental evidence has demonstrated that the integration of glucose oxidase-loaded porous metal-organic frameworks, photothermal nanomaterials, and antioxidant hydrogels within dissolvable MNs achieves synergistic bactericidal effects, accelerates collagen deposition, and enhances neovascularization in diabetic wound models.

Polyurethane (PU), a segmented block copolymer with chemically resistant urethane linkages and tunable architecture, presents persistent biological recycling challenges. This study presents a Bacterial Laccase-Mediated System (BLMS) derived from for efficient degradation of polyester- and polyether-PU. Utilizing the laccase CotA and mediator 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), the BLMS demonstrated effective de polymerization of both commercial and self-synthesized PU foams, including polyester- and polyether-types.
