Use of Poly (𝜺-Lysine) Dendrons: A Strategy Targeting Bacterial Quorum Sensing and Biofilm Formation

Figure 2

Influence of hyperbranched poly (𝜀-lysine) dendrons on growth of Pseudomonas aeruginosa NCTC 10662 (semilogarithmic graph). Dendrons of increasing lysine generation numbers were added (at an equimolar concentration of NH₂ groups, Table 1) during initial stages of cellular attachment (at approximately 1 h after setup) to stainless steel discs, as indicated by the arrow. The data represent mean values of experiments performed in duplicates. Error bars are means ± SD. 𝑃≥0.9, ANOVA.
