The article discusses how storing drinking water in containers can lead to the growth of harmful bacterial biofilms, which are difficult to eliminate with traditional disinfectants.Scientists are exploring nanotechnology as a potential solution, focusing on light-activated chemicals that can destroy microorganisms.

Researchers Lijo Mona and Muthumuni Managa highlight that nanoparticles, when exposed to sunlight, generate reactive oxygen molecules that damage bacterial cells, preventing biofilm formation.This method is particularly important in South Africa, where many rural areas face water shortages and rely on stored water from polluted sources.

The review emphasizes that while nanotechnology shows promise, challenges remain, such as effectiveness against certain bacteria and ensuring safety from toxic byproducts.Future research aims to improve these methods for real-world applications, ensuring safer water storage systems.
