A fresh idea tackles a growing need. As more places allow cannabis use, people want to know how much THC is in the air. This new tool can help by spotting tiny amounts of the active compound. The sensor works differently from older gadgets. It uses a special screen‑printed graphene electrode that h
Drugs like amphetamine are often used in crimes, especially at parties and clubs. These drugs can be dangerous, and detecting them quickly is important. Traditional methods for detecting these drugs are slow and complicated. Now, there's a new tool that could change the game. It's a wearable device
Scientists have come up with a clever idea to check for harmful chemicals in fruit. They made a special tool that can tell if there is too much of a substance called carbendazim (CBZ) in fruits. This tool is made from tiny sheets of a special material called sulfur-doped graphitic carbon nitride, de
TBBPA is a nasty chemical found in many places. It is toxic and can harm living things. So, scientists are always looking for better ways to find it. They want methods that are simple, cheap, and reliable. One new method uses a special kind of sensor. This sensor is made from a mix of copper and org
Pesticide residue detection is crucial for food safety. A new sensor has been created to spot Benomyl, a common pesticide, in fruits and vegetables. This sensor uses a special mix of materials to boost its performance. The key ingredients are Cu-BTC and FeCo-ZIF, which are turned into N-doped carbon
Imagine trying to keep track of something as tiny as a molecule. That's the challenge scientists face when monitoring diquat (DQ), a chemical that can be harmful to humans. DQ is often found in agricultural samples, so it's important to have a quick and easy way to detect it. This is where nanotechn
Picture this: tiny, super-selective sensors scouring through food to keep us safe. These aren’t your everyday sensors; they’re molecularly imprinted electrochemical sensors (MIECSs), crafted from something called molecularly imprinted derivative materials (MIDPs). Think of them like lock and key sys
Have you ever wondered how we can spot chemicals in our environment? Enter electrochemical sensors! These clever gadgets use electricity to identify specific substances, playing a crucial role in healthcare and environmental protection. But how are these sensors made? Two common methods are screen-p
