IIT-H’s device detects heart attack early:

The device can also quantify the extent of infection and does not require a trained technician to use it. “It can be used as a point of care device and will be particularly useful in rural areas where diagnostic facilities are not available readily. People in endemic areas can keep the device at home and when someone in the house falls sick,they can test if there is infection,” said the lead researcher,Shiv Govind .

IIT-H’s deviceto detect infectious diseases :

People in endemic areas can keep the device at home and when someone in the house falls sick, they test if there is infection,” said Shiv Govind Singh, leader of the team. The biochip comprises of a sensing platform integrated with a three-electrode system. The sensing electrode consists of antibody conjugated nanofibers. In the case of the device which has been tested, nanofibres were conjugated with histidine-rich protein II antibodies, which are specific to malarial antigen. Upon recognizing the presence of even a trace of malaria’s biomarkers in blood serum, the device registered a signal. It is calibrated to assess the quantitative level of infectious biomarker present in the sample. Samples obtained from a hospital were tested using the device. The device is highly sensitive. It can detect malaria parasite at a concentration of even as low as a trillionth of a gram in a millilitre. This means it can detect minutest presence of a parasite, and help detect the infection on day one itself. Dr. Singh said he and his team members were working on taking the device to the next level wherein the diagnosis could be transmitted to a medical professional via a smart phone. In addition, they are working on a device through which several diseases could be detected in one go.

You Can Now Spot Milk Adulteration, Courtesy IIT-H Team:

The team led by Prof Shiv Govind Singh, Department of Electrical Engineering, IIT Hyderabad, has developed a detection system to measure the acidity of milk. The detector has an indicator paper, that will change colour if the milk is acidic. But the novel method, with nearly 100 per cent acuracy, seeks to detect contamination through sensing changes in the biophysical properties of milk, such as acidity, electrical conductivity and refractive index (passage of light through material), the researchers said, in the paper published in the journal Food Analytical Methods. As a first step, the team led by Professor Shiv Govind Singh, developed a sensor-chip based method for measuring pH, an indicator of the acidity.The team has also developed algorithms, and incorporate it onto a mobile phone, enabling it to detect the colour change accurately.
