Researchers from Tokyo Metropolitan University have developed nanostructured alumina surfaces that are highly antibacterial and can be used for cell culture.
The nanostructured surfaces resist bacterial growth and do not interfere with cell cultures, making them ideal for regenerative medicine.
These surfaces have been prepared using electrochemistry in concentrated sulfuric acid and show unprecedented resistance to bacterial contamination.
The technology offers a sustainable alternative to antibiotics for producing high-quality cell cultures without bacterial contamination.
