The figure illustrates the formulation approach for the Bri@LDH/Thermogel drug transport system and the dual-regulation approach for drug liberation are visually represented as follows: 1: drug liberation via negative ion substitution from LDH NPs to the thermogel framework; 2: drug diffusion through the thermogel framework to the tear film.
