powderALD technology (PALD)

Effective coating can prevent the active ingredients of vaccines from being affected by environmental factors, while achieving sustained release function and prolonging the effective time of vaccines. There are many methods for preparing coatings, but powder atomic layer deposition technology (abbreviated asPALD, as a precise and controllable nano coating technology, has been widely used in new energy, catalysis, and interface modification applications of metal powders in recent years, but it has rarely been applied in the research of drug powders.
