In vivo mucoadhesion assessment of nanoformulations. SEM images of healthy eyes at (a) h12 and (b) 4 days post-instillation of different formulations. EDS mapping of phosphorus distribution for the corresponding healthy eyes. Scale bars: 10 μm. (c) Corneal retention of P was analyzed by ICP-OES with the various p(MPC-co-DMA) samples. Values are mean ± SD (n = 6). *p < 0.05 vs. p(MPC) group; **p < 0.005 vs. p(MPC) group
