Ever wondered what the level of antibiotics in your food or water is? Even if the question crosses one’s mind, it’s not easy to measure it. But an affordable sensor developed by IIT-B promises to check the level of the antimicrobial substance in our eatables without the help of an expert.

Antibiotics are widely used to treat bacterial infections in humans and animals. They are even used in household items such as floor cleaners and soaps. They enter the environment from these sources and contaminate our food and water, giving a chance to the bacteria to become resistant to the medicines that are meant to kill them. It means that the drugs we could use to treat a particular disease may no longer be effective.
