FIGURE 6
ALG-AgNPs exert their biocidal action against Mycobacterium tuberculosis via an increase in bacterial cell-wall permeability. Log phase Mtb H37Ra cells were treated with or without 50 μg/ml ALG-AgNPs for 24 h. Then, the bacteria were stained with propidium iodide. The images were observed at 400× magnification by fluorescence microscopy. Scale bar represents 100 μm.
