Azadirachta indica, commonly known as neem or Indian lilac, is a tree in the mahogany family Meliaceae. It is native to the Indian subcontinent. Products made from neem trees have been used in the traditional medicine of India for centuries.

In a novel use of neem tree oil, researchers from the IIT-H have developed neem oil encapsulated electrospun polyurethane nanofibrous bags for seed storage. The real-time storage experiment carried out for 75 days showed that 90 per cent of the seeds stored in these bags were uninfected, while 70 per cent stored in commercial bags were found to be infected with storage fungi.

The research, led by Chandra Shekhar Sharma, Associate Professor in the Department of Chemical Engineering at IIT-H, demonstrates the suitability of neem oil bags as an ideal storage system. “Polyurethane is the most favoured versatile polymer, and polyurethane nanofibers are elastic, semipermeable, thermally-stable with excellent strength."
