Webb22 jan. 2024 · PLGA experiences hydrolytic degradation, which is triggered immediately upon contact with aqueous solutions and generates acids, which in return catalyze the hydrolysis [ 17 ]. Bulk erosion has been found to be the main degradation pathway for PLGA, although polyester can also suffer surface erosion. WebbPLGA with a higher ratio of lactic acid to glycolic acid degrades more slowly than PLGA with a lower ratio. This is because lactic acid is more hydrophilic than glycolic acid, which means that it attracts water molecules and promotes hydrolysis, the process by which PLGA breaks down into its constituent parts. black desert online catch a horse https://jessicabonzek.com
