1PCB based Electrode Biosensor using Graphene Nano ink●Dr. P. Praveena
●Dr. Silpa
This is a low cost electrode system that consists of working ,counter, reference
electrodes that can be used in the same way as that of the screen printed electrodes. The
electrode system is made using plain copper clad board and naturally synthesized
graphene ink.

The radiofrequency identification tag has many applications in various fields. RFID technology has been extremely used in identification of animals and pets where an RFID chip with an IC is inserted into the animal skin. The RFID tags could be used in sensing volatile compounds as passive sensors. The passive tags use power from the radio waves which interrogates on it. The RFID could be used for biosensing applications for detection of various analytes, which could be of biological importance. Conventional method of antigen -antibody detection involves ELISA test and other technologies which would use different labelling techniques. The proposed biosensor could be used to detect the antigenic materials without any labelling of the molecules. The RFID tag is a single Antenna or an array of antenna in a compact package. The tag may or may not be fitted with a microchip. The antenna is used for picking up the reader signals. The RFID tags do not use power as such and hence is classified under passive tags. The operating frequency is frequency which excites the RFID tag to a certain wavelength. The operating frequency depends upon the geometrical as well as the innate properties of the RFID tag. The interrogating signal is blasted onto an RFID antenna and the response from the backscattered waves are analysed for the modulations. The processing of the backscattered waves would tell us the concentration of analyte present. When the radio waves are incident on the RFID tag the power transferred to the tag and the reflected power measured by the reader. A control tag is provided which provides as a reference for the working tag. The non labelling technique proposed here simplify the existing technologies and methods. The proposed invention could be implemented to broad areas of technologies, sensors for microfluidics, cancer detection, pathogenic microorganism detection, toxicology etc.

3Biome Organic Air Purifier- using Arthrospira platensis for air purification●Dr. Dhanya Gangadharan

The global average atmospheric carbon dioxide in 2017 was 405.0 parts per million (ppm for short), with a range of uncertainty of plus or minus 0.1 ppm. Carbon dioxide levels today are higher than at any point in at least the past 800,000 years. Even though its effect isn’t noticed in large scale, it heavily affects the occupant’s health in confined office spaces with a large occupant to floor area ratio. To curb both these problems in a single device by changing the design function of Photo bioreactor from biomass production to CO2 sequestration. The aim of this project is design and fabricate a compact Photo bioreactor which can absorb ambient CO2 and convert it to edible algal biomass (Spirulina Plantesis) and O2; and also, to device a simple Pre-filter that absorb and trap basic contaminants and allergens in air. A methodology has been researched and developed to sustain a continuous algae culturing system with essential Growth support system.

The patent developed a biofilter which was economically feasible by using locally available herbs and materials that had the potential to purify water. The team was able identify certain locally available leaves as well as fruits, seeds and wood bark that could be used for the purification process. These 16 herbs were mixed with burned coconut shells and carbonized rice husk. A filter bed is constructed with all the necessary components from these herbs and are placed between the containers for getting the purified water.

The present invention uses a solid substrate (chromatographic paper) and the coloring reagent is an azo dye micronized to finer particles. A stabilizer which is a carbohydrate is mixed with the coloring agent in the ratio 5:1. The quantification part is a sophisticated electronic circuitry. The detection is based on the light refraction- absorption-reflection ratio. The device works in accordance with digital image processing technique. A IMX219 sensor with 2p lens is used as a sensor to analyze the specimen (Marijuana with saliva). The result is displayed at a 2.4inch OLED display. The whole device is powered by an appropriate battery.

Melanin-based bio panel (MBP) technology is believed to offer an effective way to solve the inefficiency of the silicon- based solar panels. Melanin is the pigment which is acting as a colorant in animals, plants and human body giving the hair and skin their characteristic color. The technology makes use of melanin from hair in solar panels replacing silicon, as light absorbing material to generate electricity.

1A nanomaterial based electrochemical sensor for the detection of anti cancer drug moleculesMs.Pooja Das Manjulabhai Dr. Dhanya Gangadharan Dr. Jeethu Raveendran Mr. Arun WarrierIndian20234102201303/04/2023
The patent aims to a method of determining the concentration of anti- cancer drugs in cancer patients who are undergoing chemotherapy regime using electrochemical sensor electrodes. Here screen-printed carbon electrodes were fabricated to determine the drugs Erlotinib hydrochloride, Sunitinib malate in blood. The limited publication available in the proposed area and the vital necessity for a cost-effective, rapid and accurate method for therapeutic drug monitoring [TDM] in cancer chemotherapy justifies the requisite and novelty of the project. It helps to minimize the use of sophisticated instruments and trained personnel for the quantitative evaluation of drugs and helps to reduce the cost of diagnosis and reach to a large group of population in the developing and underdeveloped countries.
