Resumen:
Mosquitoes are insects of major public health concern because many species are vectors of diseases, such as malaria, yellow fever, or dengue. Repellents are commonly used to avoid mosquito bites. There is a special interest on natural repellents due to their low toxicity and eco-friendly nature [1]. However, their high volatility to fabrics has proven to be inefficient in prolonging the repellence for long enough. Microencapsulation is an alternative to retard the release of volatile compounds [2]. In this work, a naturally derived repellent was microencapsulated by electrospray with a biocompatible polymer in order to control its release. The effect of the encapsulation method on the morphology and release profiles of matrix and core-shell microparticles was studied. The results are part of FONARSEC FS Nano2010-02 Project "Nanotechnology for functional textiles".
