Analysis of mucoadhesive property of MPs in small intestine. 4 mg of each of FDA-loaded MPs was dispersed on a freshly excised porcine intestinal mucosa and incubated at 37 °C for 1 h with shaking at 100 rpm. The MPs attached on the mucosa were collected and remaining concentration of each MPs was calculated by measuring the absorbance of FDA at 490 nm (n = 3) (*p < 0.05 by t-test)
