Abstract Scope |
Bacterial infections in biomedical devices remain a major concern, particularly with the rise of antibiotic-resistant strains. Instead of relying on chemical solutions like antibiotics or antiseptics, we raw copper pellets formed into highly tortuous latticed cylinders based on triply periodic minimal surfaces (TPMS), fabricated through a hybrid 3D printing–casting approach. The goal is to create a metal-based filter through which bacteria-laden fluids are both trapped and neutralized via copper ion interactions. The highly parametrized TPMS geometry provides a tunable, tortuous path for fluid and bacterial flow, thereby enhancing contact-driven antimicrobial action. Performance was evaluated against two controls: a bacterial solution and a solid, non-latticed copper cylinder. Initial tests with E. coli and Bacillus strains indicate that the latticed copper cylinder significantly reduces bacterial load compared to the controls. This solution offers a low-cost, versatile approach to bacterial control, applicable from plumbing to biomedical devices. |
