AFM micrograph obtained from the 30–70 HA/PLGA/chitosan colloidal gels. (a) In the 5 μm by 5 μm scan size, raised, darker regions represent ridges and nanosized pores. (b) The control shown here, as a 1 μm by 1 μm scan of the image shown in 3(a), displays a smooth, flat region that is thoroughly consistent.
