Biofilms are often more resistant to toxic chemicals such as heavy metals and antimicrobial agents than planktonic cells. Nanosilver has a broad range of applications with strong antimicrobial activity. However, biofilm susceptibility to nanosilver toxicity is not well understood. We studied the bacterial activity in planktonic or biofilm cultures after nanosilver exposure using oxygen quenching fluorescence-based microrespirometry. We also determined the aggregation behavior and the spatial… CONTINUE READING
