Fig. 4From: Repellent active ingredients encapsulated in polymeric nanoparticles: potential alternative formulations to control arbovirusesIn vitro release assay of IR3535 and GRL from PCL nanoparticles and PCL nanoparticles incorporated into hydrogels. The release assay was performed using the vertical diffusion cell system at 32.5 °C, in aqueous media containing 3% of PVA as co-eluent over 30 h.
