1. Label-Free Nano-biosensor for Flavivirus detection
Holistic disease management with accurate and timely diagnosis has been recommended as a component of a strategic vision aimed at improving outbreak response capabilities, altering behavioral disease patterns, and decreasing disease burden. Although Flavivirus has been identified in biological samples, the early screening of the virus has remained a demanding task that requires significant development of effective detection technology. We are developing a label-free nano-biosensor for flavivirus detection based on the antigen–antibody specific interaction as shown in the figure. The green-synthesized nanomaterial-based printed biosensor is the major novelty of the product to improve the selectivity and sensitivity for distinctive protein concentrations.

The proposed nano-biosensor will be a product that will be beneficial to the sensor industry and healthcare sector.

1. Hybrid Supercapacitor
The supercapacitor can store larger capacitance than normal capacitors and supports fast charging/discharging capability. However, the major problem with the supercapacitor is lower energy density compared to electrochemical batteries. We are developing a hybrid supercapacitor, i.e., a combination of ELDC and pseudocapacitor, which can also offer high power and energy density.

1. Development of a bladeless fan
Bladeless fans are more energy-efficient and safer due to the hidden blades, easier to clean, more adjustable, and sleek designs. From a performance point of view, bladeless fans are better because they multiply mass flow rate, eliminate buffeting, consume less power, and are quieter. A schematic (not the actual one under design) bladeless fan is shown underneath.

2. Development of wind-solar powered charging units
The major innovation is on the design of the Wind Turbine to increase its aerodynamic efficiency by inducing Protuberances on its leading edge and thereby increase power production. Further to this, ac generators play a vital role in wind generation applications. High efficient PM generator is designed with a maximum output power of 1.1 kW with its necessary power controllers to make the designed wind turbine more efficient.
