Device Overview
AroTrack is a portable and low-cost solution. which is roughly the size of a small projector. The device was created by a team led by Professor Ruchi Anand and Professor Rajdip Bandyopadhyaya, which employs a biosensor known as MopR, developed in 2017 from Acinetobacter calcoaceticus bacteria.
Detection Mechanism
The device detects pollutants by causing a colour change in the water sample. When mixed with the sample, the proteins react chemically to aromatic compounds. AroTrack measures the intensity of the colour change by shining light through the sample. Higher absorbance indicates a greater concentration of pollutants.
Affordability and Accessibility
AroTrack is designed to be affordable, costing around $50 (less than ₹5,000). Its user-friendly design allows anyone to operate it, regardless of technical skills. This accessibility is crucial for communities with limited access to expensive lab tests.
Performance and Testing
The device can detect pollutants at very low concentrations, ranging from 10 to 200 parts per billion. It has been tested in both simulated wastewater and real environmental samples. AroTrack remains effective in water temperatures up to 50°C. It provides results in under 30 minutes, making it suitable for rural and low-income areas.The team is working to enhance AroTrack’s capabilities, which aim to expand the range of detectable pollutants, including more complex chemicals. Currently, AroTrack is in the prototype stage, with further testing planned for refinement and broader application.
