We studied a model system of controlled drug release using beta carotene and k-carrageenan/NaCMC hydrogel as a drug and a device, respectively. Electrostatic interactions between beta carotene and k-carrageenan/NaCMC polymer segments are strong, since beta carotene is positively charged, NaCMC is a...
