Assistant Professor (Scientist-D)

We work in the following area:
Food microbiology/fortification: Fabrication of nano-paper/device for food processing/preservation/protection.
Food/agri sensing: Designing sensors with nanoparticles for optical/electrical language decoding.

Research Interest

  • Food microbiology/fortification

  • Smart plant nutrient/biocontrol application

  • Food/agri sensing

Research Highlights

  • Upconversion Nanodevice-Assisted Healthy Molecular Photocorrection of Mushroom

    Upconversion nanoparticles with the property to convert deep-penetrating near-infrared radiation to UV radiation have been cast into a disk to use sunlight and emit UV radiation for vitamin D conversion.

  • Ecofriendly Fruit Switches: Graphene Oxide-Based Wrapper for Programmed Fruit Preservative Delivery to Extend Shelf Life

    The synthesized graphene oxide wrapper shows efficient preservative release with the stimuli of the overripe fruit juice and improves the fruit shelf life.
  • Nano-hives for plant stimuli controlled targeted iron fertilizer application

    Carbon nanomaterial and mesoporous silica were used for the smart preservative and targeted agro chemicals application. The fertilizer coating acts as a gate, which closes the pores in the presence of carbonate ions to keeps the iron in phyto-available forms, whereas open the pores in the presence of the uptake proton signal from the roots.
