Thread: povidone-iodine

hi, im working on my IB Extended Essay and i need to know the antimicrobial mechanism of povidone-iodine, the active ingredient in Betadine. Any help would be appreciated....

Povidone iodine acts by destroying microbial protein and DNA. How? Due to the strong oxidizing effects of free iodine on functional groups of amino acids, nucleotides and double bonds of unsaturated fatty acids.
