Bioactive compounds/molecules controlled release

Multiple emulsions may be interesting ways for releasing bioactive compounds in a controlled rate, useful in cosmetic, pharmacy, agricultural, and industrial chemicals nevertheless, their commercial applications have been limited due to their thermodynamic instability and unexpected fast release of encapsulated bioactive molecules (Yoshida et al., 1999 Beer et al., 2013). 

The selective activation of compounds with potential therapeutic effects and the controlled delivery of bioactive molecules triggered by light are topics of intensely growing interest (6,197-200). Besides the search for light-sensitive prodrugs activated by photochemical cleavage, isomerization or photoredox processes (201-203), especially the release of small molecules such as NO, CO, CS2, and H2S, have attracted a lot of interest in the past years (204-208).
