Fig. 5From: Revolutionizing ocular drug delivery: recent advancements in in situ gel technologyIn situ gel formation on the ocular surface. When administered into the eye, the formulation, which contains nanoparticles dispersed in the liquid phase, quickly transforms into gel in the cul-de-sac of the eye in response to environmental changes like pH, temperature, and ions before slowly releasing the medication under physiological conditionsBack to article page
