AIM: To fabricate ultra-small algal chitosan nanoparticles (US CS NPs) for efficient delivery of bovine lactoferrin (bLf) to ocular tissues through topical administration to prevent carbendazim-induced toxicity. MATERIALS & METHODS: Rat eye model was used to evaluate the in vivo biodistribution the US CS NPs and bovine eye model was used for evaluating ex vivo biodistribution. Human lens epithelial cell line (HLEB-3) model was used to evaluate the in vitro toxicity, uptake mechanism and in vitro efficacy of the synthesized bLf-US CS NPs over carbendazim-induced ocular toxicity. RESULTS: The in vivo and ex vivo biodistribution results suggest that the ultra-small CS NPs efficiently internalize into the ocular tissues within 1 h after administering topically. Ultra-small algal nanocarriers to encapsulate bioactive antioxidant bLf protein and evaluated its potential in inhibiting carbendazim-induced human lens cell apoptosis and oxidative stress. CONCLUSION: US CS NPs could be explored for their potential for delivering various ocular drugs through topical administration for other eye diseases including cataract, glaucoma and age-related macular degeneration.
