Researchers at the Institute of Nano Science and Technology (INST) Mohali, have developed novel electrochemical and optical sensors using a new group of nano polymer materials.
About the Novel Nanopolymer:
Novel nanopolymers are innovative polymer materials that incorporate nanostructures or nanoparticles to impart unique properties.
- They are prepared using various methods like vapor condensation, vacuum evaporation, electrospinning, and chemical synthesis to create nanofibers, core-shell structures, hollow fibers, and tubes with diameters down to a few nanometers.
- Examples: Silicon nanospheres that are much harder than regular silicon, with hardness between sapphire and diamond, and bio-based N-heterocyclic poly(aryl ether ketone) with high biomass content and superior properties
- Applications of Novel Nanopolymers:
- Biosensors and optoelectronics utilizing the fluorescence and magnetic properties of nanoparticles.
- Drug delivery, tissue engineering, and gene therapy using biodegradable nanoparticle systems.
- Forensics for drug detection, fingerprinting, DNA analysis, and sensors.
- High-temperature-resistant plastics with improved properties.
