WebSimple stains use one dye and all cells are stained the same color. Bacteria have a negative charge and dye has a positive charge; therefore, color is attracted to the cell. In negative stain it stains the surroundings since the dye has a negative charge therefore, color is repelled by the cell. WebThus, dye absorption is enhanced due to the superior ionic interaction of dp-TH or p-TH COFs with counter-charged dyes. For MB absorption, k values were calculated as 0.19 ± 0.06, 1.27 ± 0.64, and 0.002 ± 0.0005 for TH, dp-TH, and p-TH COFs, respectively. As expected, the selectivity coefficient of dp-TH COFs for the MB dye is higher than TH ...
