Fig. 6From: A zeta potential value determines the aggregate’s size of penta-substituted [60]fullerene derivatives in aqueous suspension whereas positive charge is required for toxicity against bacterial cellsInfluence of positively charged [60]fullerene derivatives on zeta potential of Escherichia coli K12 TG1 cells. The zeta potential distribution for intact (c) and treated with toxic concentrations of F6 (1), F2 (2), F8 (3), and F4 (4) bacterial suspensions.Back to article page
