Microgels for Long-Term Storage of Vitamins for Extended Spaceflight

This study showed that PVCL microgels drastically improve the water solubility of hydrophobic retinol. Additionally, it is demonstrated that the highly crosslinked microgel particles in aqueous solution can be utilised to greatly retard the light- and temperature-induced isomerisation process of retinol by a factor of almost 100 compared to pure retinol stored in ethanol. The use of microgels offers various advantages over other drug delivery systems as they exhibit enhanced biocompatibility and superior aqueous solubility.
