ABOUT US

We work at the interface of material science and sensors. Nanomaterials for chemical and biological hazard diagnostics, extremely weak electric and magnetic field detections, sonar detections, biosensors are few of the niche areas of this group research. We also work on optical materials and explore their non-linear properties for applications in sensing and engineering them as photonic devices. Using engineered structures, we have prepared unit-cell metamaterial structures for CBW detections, hybrid fuel detections and fuel-adulteration studies. Radar absorbing materials (RAM) are explored using specific nanomaterial polymer composites.

Few details of the problems being pursued are:
1. Development of SOx and NOx derivative based gas sensors for qualitative and quantitative sensing by using various gas sensors. Hazardous chemical and biological molecule sensing, flex fuel/ adulterated fuel sensing using portable devices.

2. Design and development of electronic interfaces for the developed sensors such as digital and analog designing, algorithm developments, testing and validating at circuit/module level.

3. Modelling and simulation of various sensor devices for optimizing its performance. These are used for developing sensor networks and machine learning algorithms.

4. FPGA and embedded signal processing for RADAR, RCS measurement and various modulation techniques used in communication.

5. Extremely low magnetic and electric field sensing- using optical fiber based sensors.

6. Synthesis of thin films for EMI shielding using polymer nanocomposites, nanocarbon/MXene based additives- flexible, coatings, paint incorporated and sprays.

7. Biosensors: For disease diagnostics and biological applications using nanotechnology.

8. Drug Delivery : For wound healing applications, pain relief and ocular drug delivery.

The lab is also involved in the development of micro-needle patches for analgesic and wound heeling applications. We also work on sustained drug delivery systems by implementing biosensors for detection of dengue, blood sugar, venom and bilirubin.

"Our lab is associated with QTF Lab of DIAT along with the Advanced sensors lab in order to increase the diversity and efficiency of the research work."
