IIT Delhi’s Smart Mosquito-Repellent Detergents to Protect Against Malaria and Dengue
New Delhi, Nov 27 (IANS) – Amid a rise in mosquito-borne diseases such as malaria, dengue, and chikungunya, researchers from the Indian Institute of Technology (IIT) Delhi have developed an innovative mosquito-repellent detergent. This groundbreaking product aims to provide a new layer of protection against these dangerous diseases.
The Need for Effective Mosquito Protection
Currently, various protective measures against mosquitoes are available on the market, including:
- Liquids
- Coils
- Lotions
- Creams
- Roll-ons
- Sprays
- Patches
While these options offer some level of protection, they come with limitations. For instance, topical formulations like creams and lotions may lose their effectiveness over time, increasing the risk of mosquito bites and the associated diseases.
Innovation at IIT Delhi
The newly developed mosquito-repellent detergents are available in both powder and liquid forms, maintaining comparable wash-care properties. According to Professor Javed Nabibaksha Sheikh from the Department of Textile and Fibre Engineering at IIT Delhi, “We have developed smart detergents to protect people from dangerous mosquito-borne diseases. The products have been tested in a commercial laboratory and have proven effective at repelling mosquitoes.”
Testing Methodology
The testing of these innovative detergents involved a unique “hand-in-cage” method. In this method, volunteers inserted their hands, covered with fabrics washed in the new detergents, into a box containing starved mosquitoes. The number of mosquitoes landing on the fabric was then evaluated. Results showed that fabrics washed with these detergents demonstrated a significant reduction in mosquito landings.
How the Detergents Work
One of the critical aspects of this innovation is the interaction between the active components of the detergents and the fabric fibers during the washing process. This interaction makes the textiles less attractive to mosquitoes, thereby reducing the likelihood of bites. Professor Sheikh explained, “The active components work on both the smell and taste sensors of the mosquitoes.”
Durability and Regeneration of Properties
Since textiles are frequently washed, the mosquito-repellent properties of the fabrics regenerate with each wash, ensuring both efficiency and durability. This feature is particularly significant for individuals living in areas prone to mosquito-borne diseases, as it provides ongoing protection without the need for constant reapplication of topical products.
Commercialization and Future Prospects
A patent for this innovative product has already been filed, and the commercialization of these mosquito-repellent detergents is expected soon. This development could significantly impact public health, especially in regions where mosquito-borne diseases are prevalent.
Conclusion
The introduction of smart mosquito-repellent detergents by IIT Delhi represents a promising advancement in the fight against mosquito-borne diseases like malaria and dengue. By integrating mosquito-repellent properties into everyday laundry products, this innovation not only enhances personal protection but also contributes to broader public health efforts.
