Atomic force images of DNA-chitosan complexes at different chitosan concentrations and pHs. The concentration of Figure (a–d) chitosan is 0.1 µM, 0.15 µM, 0.35 µM, 0.45 µM, ( $k = 0.95, 1.43, 3.33, 4.28$ ) respectively, pH = 4.6. Similarly, in (e–h), the concentration of chitosan is 0.15 µM, 0.2 µM, 0.25 µM, 0.3 µM, ( $k = 1.43, 1.9, 2.38, 2.85$ ), respectively, pH = 7. In (i–l), the concentration of chitosan is 0.2 µM, 0.26 µM, 0.28 µM, 0.36 µM, ( $k = 1.9, 2.47, 2.66, 3.42$ ), respectively, pH = 8.
