Detection of FITC loaded by CS/TCS-SA NPs in rat corneas. The rats were divided into 3 groups; FITC only, FITC-loaded CS-SA NPs, and FITC-loaded TCS-SA NPs. FITC were topically treated for 1.5 h. A-C: Representative images of stereomicroscope. D-F: Representative images of CLSM of peripheral cornea. G-I: Representative images of CLSM of central cornea. FITC displayed green fluorescence and nuclei were counterstained with DAPI (blue). Representative images from five individual animals are shown.
