Cover Story: Dual-responsive alginate/PNIPAM microspheres, responding to both pH and temperature variations, are developed for the controlled delivery of bioactive lipophilic compounds. The microspheres are fabricated using a microemulsion-based electrospray technique without the use of toxic solvents. A chitosan coating is added to improve stability and degradation control. DSC is used to assess the thermal response of the microspheres, while degradation assays at different values of pH and temperature unveil their dual-responsive behavior. This work offers a promising approach for the targeted delivery of Ozoile, stable ozonides derived from olive oil, particularly useful in the context of oxidative stress modulation and inflammation management.
