These materials possess exceptional electrical, mechanical, and surface properties, which enhance the sensors' ability to detect minute concentrations of analytes with high accuracy. Graphene's large surface area facilitates greater interaction with target molecules, while carbon nanotubes improve electrical conductivity and signal transduction. According to an article published by ACS in 2023, researchers developed a self-powered nanosensor that can detect small amounts of mercury ions with just a tap. The sensor, integrated into a robotic hand, uses the triboelectric effect to generate electricity and signal the presence of mercury ions. It is highly selective and can detect ions in water and food samples. This increased sensitivity and specificity enable the detection of trace levels of chemicals, making sensors more reliable for applications in environmental monitoring, healthcare, and industrial safety.

Environmental Monitoring and Safety Applications

The surge in environmental regulations globally is significantly boosting the adoption of chemical sensors, as industries strive to comply with stringent air and water quality standards. Real-time monitoring capabilities enable immediate detection of pollutants, facilitating swift pollution control measures and minimizing environmental impact. For instance, in March 2024, MIT chemists developed a sensor that can detect "forever chemicals" known as PFAS in drinking water. The sensor can detect PFAS levels as low as 200 parts per trillion in a water sample, offering a faster and cheaper alternative to current detection methods. The researchers are working on a larger-scale device to increase sensitivity and envision a user-friendly household system for PFAS detection. In industrial settings, chemical sensors play a crucial role in ensuring safety by continuously tracking hazardous substances, thereby preventing accidents and protecting workers. In line with this, public health initiatives benefit from precise environmental monitoring, allowing for timely interventions to safeguard communities from harmful pollutants. This heightened focus on environmental stewardship and safety underscores the essential role of chemical sensors in promoting sustainable and healthy living environments.
