Scientists at Tokyo Metropolitan University have developed anodic porous alumina (APA) surfaces with extraordinary antibacterial properties that also promote cell growth.
The nanostructured surfaces disrupt bacterial cell walls, preventing bacterial growth while enabling the safe proliferation of mammalian cells.
The APA surfaces offer a safer alternative to antibiotics in cell culture and regenerative medicine applications, reducing the risk of antibiotic resistance.
The ease of manufacture and potential for widespread adoption make these surfaces valuable for creating sterile environments in laboratories and hospitals.
