From: Inactivation of mammalian spermatozoa on the exposure of TiO2 nanorods deposited with noble metals
Spermatozoa were incubated with alizarin red S (ARS, red), and stained with PNA (sperm acrosome, green) and DAPI (DNA, blue). A Control (without [W/O] catalyst), B TiO2 NRs, C Ag-loaded TiO2 NRs, and D Au-loaded TiO2 NRs for 4Â h. E TEM image of TiO2 NRs attached to sperm acrosome and nuclear membrane (white arrows). F TiO2 NRs attached to spermatozoa inhibited sperm penetration during IVF
