This research develops an electrochemical sensor to continuously monitor stress by detecting cortisol, a key stress hormone. Using DNA aptamers and nanostructured electrodes, the sensor overcomes traditional detection limits, improving signal strength and durability. The technology offers a noninvasive method for long-term stress tracking to support prevention and treatment.

Corn crops often suffer hidden stress long before visible damage appears. This research develops DNA aptamer-based biosensors that detect early stress signals in maize soil. By providing real-time alerts, the system enables faster intervention, improving crop resilience, farm productivity, and long-term food security.

This project develops an “Aptamer Express,” a DNA-based Trojan horse designed to bypass the brain’s protective barriers, target tumours, and deliver cancer-killing drugs directly to brain cancer cells. The approach aims to overcome treatment resistance, improve precision, and reduce side effects, offering new hope for patients and their families.
