Mosquito-repellent controlled-release formulations for fighting infectious diseases

Area of Science:

• Pharmacology
• Entomology
• Materials Science

Background:

• Malaria and other mosquito-borne diseases pose significant public health risks globally.
• Current personal repellents have limited long-term efficacy, requiring frequent reapplication.
• Controlled-release repellent systems offer a promising alternative for sustained protection.

Purpose of the Study:

• To review repellent controlled-release formulations for mosquito-borne disease control.
• To investigate mathematical models governing repellent release kinetics.
• To highlight the potential of advanced repellent systems for public health improvement.

Main Methods:

• Comprehensive literature review of controlled-release repellent technologies.
• Analysis of various encapsulation matrices: polymer microcapsules, micelles, nanoemulsions, liposomes, etc.
• In-depth discussion of mathematical models (Higuchi, Korsmeyer-Peppas, Weibull, Mapossa) for release rate prediction.

Main Results:

• Encapsulation technologies enable sustained release of repellents, overcoming limitations of conventional products.
• Mathematical models provide frameworks for understanding and optimizing repellent release profiles.
• Diverse formulations show potential for effective mosquito vector control.

Conclusions:

• Controlled-release repellent systems represent a significant advancement in combating mosquito-borne diseases like malaria.
• Optimized formulations can provide long-lasting protection, reducing disease transmission.
• These technologies contribute to improved public health by offering broader protection against various mosquito vectors.
