In our daily life we use a variety of products from chemical industries such as plastic products, fuels like gas and oil in cars and so on. Do you know that a material called catalyst is used in all these chemical processes to produce these kinds of products? If we could understand how this catalyst worked during the chemical reaction, we can make sure that it does their job properly. My research is all about developing a tiny sensor that can monitor and analyse molecules that are produced during high-temperature reactions in real-time. These tiny sensors, which are 500 times smaller than a human hair, provides information such as quality and quantity of the products formed during the whole duration of the reaction. With this information it is possible to design better catalysts, which even reduces the production costs for chemical companies. Additionally, these tiny sensors can be easily optimized for other sensing applications in biology, health care, forensics and food safety etc.
