NANO TECHNOLOGY PRODUCTS

What’s in news?

Tamil Nadu Agricultural University on Tuesday released two nano technology-based products aimed at extending the shelf life of horticulture products.

Key data’s:

  • The ‘Fruity fresh’ and ‘Nano Stickers and Nano Pellets’ would increase the shelf life of fruits and vegetables and protect them against post-harvest diseases.
  • Fruity fresh is a liquid nano formulation containing hexanal that keeps fruits and vegetables fresh for more days.
  • Hexanal has also been successfully encapsulated in polymer matrix either as an electro spun fibre matrix (Nano sticker) or nano-pellets that extends shelf life of fruits by 1-2 weeks during storage and transportation
  • The ‘Fruity fresh’, when sprayed 15 – 30 days before harvest, helped growers retain fruits and vegetables for six to 12 days compared to those fruits and vegetables that were not sprayed.
  • Five more nano technology-based products were in the offing. The TNAU was working on using nano technology in agriculture inputs, post-harvest, crop protection and management and a few others.
  • One of the products that the TNAU would soon launch would be nano fibrillated cellulose or nano film, which could be used as a substitute for plastic.
  • The film, made of banana fibre, would also extend the shelf life of products when used to pack.
  • TNAU is the first State Agricultural University in India to establish an exclusive Department of Nano Science and Technology in 2009 with a view to initiate research in the crosscutting areas.
  • The seed priming technology using nano fibre matrix is ready for pilot testing. and mesoporous nano silica can be employed to impregnate any pesticide molecules to achieve higher bio efficacy and sustained release.
  • This technology can be customized by polymer industries based on their requirements and this meet would help the industries to work in coordination with Nano Centre of TNAU to commercialize these technologies at the earliest.

Nanotechnology:

  • Nanotechnology or nanotech in short, is the technology that involves the manipulation of matter on atomic, molecular and supramolecular scales. This includes particles of a scale 1 to 100 nanometers.
  • India spends only a fraction of the amount spent by countries such as the USA, China, Japan, etc. on nanotechnology.
  • The quality of research is also to be improved significantly. Only 16% of the papers from India figured in the top 1% publications in 2011.
  • Only 0.2% of the patents filed in the US Patent Office is from India in this field.
  • There are very few students who take up this field.
  • Although the target number of PhDs in nanotechnology is 10000 per year by the MInistry of HRD, the current number is just 150 per annum.
