What is it about?

Our study explores a new method to break down bacteria using a special type of material called BaTiO3. When this material is treated in a certain way, it develops a kind of "leftover charge" on its surface. This leftover charge slows down the recombination of particles when exposed to light, making it really good at breaking down bacteria. The treated material also helps create tiny molecules that can harm bacteria, and when exposed to special light, it becomes even better at fighting off bacteria. This happens because the treated material affects the bacteria's outer layer and other important parts, eventually leading to the bacteria being destroyed. Essentially, our findings show that by treating this material in a specific way, it can become a powerful tool in battling bacteria, particularly when combined with light exposure.
