1. Area of Research
1- Fiber Sensors for health care and
environmental application
Spinel and perovskite oxide based Fiber Optic
Bio-sensor are being designed and coated on a fiber with the objective to detect
the desired bio-analyte. The fiber optic sensor works on the principle of
Surface Plasmon Resonance (SPR) to detect the analyte. These sensors use sialic
acids as the analyte and follow non-invasive sensing method, hence doesn’t
require any experienced medical staff for its operation. It is highly sensitive
and have very high specificity. Currently the work is also under progress to
develop such sensors for detection of the cancer. Optical sensor based on SPR assisted
Interferometry technique is also being developed using modified optical fibers to
improve the sensitivity. The design is being optimized for efficient detection
of blood glucose level and the concentration of heavy metal ions present on the
surface of earth.

2- Waveguide based biosensors for healthcare
The search also includes development of compact
photonic biosensors using specially designed dielectric waveguide structures
for improving the sensitivity as well as reusability of the bio-sensors, and
chemical and gas sensors. This research work includes simulation of different
configurations of optical waveguides for designing cost effective, portable and
efficient invasive and non-invasive biosensors for continuous monitoring of
blood glucose level in case of diabetic patients. This work can be extended to
pathogenic detection also. Mainly this research aims to provide painless and
more effective bio detection technology as an alternative to traditional
methods.
3- Low cost Digital holographic microscope based HbA1C detection
We have developed a low cost blood glucose
detection technique by tracing the phase of RBCs of human blood with the HbA1c
level, against the conventionally used high cost instrument HPLC technique. Our
procedure includes a low cost and easily configurable Digital Hologram
Microscopy (DHM) Set-up. The phase of RBC keeps the track of glucose level in
blood for almost last three months, and tracing it in a suitable manner, can
give the trace of glucose level of the patient for last three months too. The
prototype has been prepared and is under validation. Work has also been
initiated to develop the process for early detection of malaria using DHM
technique.

Detection of heavy metals and treatment
of industry effluence
Presence of heavy metals and organic
wastes in industrial effluent are potentially harmful for the environment,
aquatic plants, animals, and human health. Silver nanoparticle are used to
detect mercury in the industry effluent. We use photocatalysis, a green process
that happens in the presence of visible light and without using any toxic
chemicals, and does not generate any toxic byproducts; to degrade the organic
wastes from industry effluence. Suitable nano composites having effective
photocatalytic activity due to their shape and size dependent unique
properties, are developed to serve this purpose.

5- Hybrid nanomaterial based Drug delivery system
A drug delivery system is a
formulation that enables the introduction of a therapeutic substance in
the body and improves its efficacy and safety by controlling the rate, time,
and place of release of drugs for more effectiveness. Through the manipulation
of size, surface characteristics and material used, the magnetic nanoparticles
has been developed into smart systems (Hybrid nanomaterials), that has potential
to deliver drug to targeted area minimizing side effects and provide controlled
release therapy.
6- Improving light output of display devices
Light emitting diodes (LEDs) such as
Organic light-emitting diode (OLED) are gaining popularity as next-generation
displays and lighting taking advantage of their low thickness, self-luminous
properties, high color purity and gamut, fast response speed, and various
applicable characteristics like flexibility and fold ability. However, the
conventional flat OLED severely suffer from its light loss due to total
internal reflection (TIR) at the glass-air interface. We are trying to reduce
this effect of TIR and hence increase the external quantum efficiency (EQE)
level and brightness by changing the layer structure and introducing
nano-particles in the OLED substrate. On that way the brightness will be
increased more than the present percentage. This work is going on through
numerical simulations and experiments by changing the structure of OLED layers.
The center also focuses on new generation solar cells such as hybrid and led free solar cells, optical fiber indoor lighting etc.
