Size effect of SnO nanoparticles on bacteria toxicity and their membrane damage.

Semiconductor SnO nanoparticles (NPs) are being exploited for various applications, including those in the environmental context. However, toxicity studies of SnO NPs are very limited. This study evaluated the toxic effect of two sizes of spherical SnO NPs (2 and 40 nm) and one size of flower-like SnO NPs (800 nm) towards the environmental bacteria E.
