Salicylaldehyde is a key player in making medicines and scents. But, it's not so great for the environment or our health. So, finding a way to spot it is important. That's where a new tool comes in. It's called HNU-90-Tb. This tool is made by combining terbium and another chemical called 4-carboxytriphenylamine. The cool thing about HNU-90-Tb is that it can handle w...

Have you ever thought about how we can detect tiny proteins in our body that are crucial for understanding diseases? Scientists have found an interesting way to do this using sugar molecules and tiny gold particles. These proteins, called glycoproteins, have sugar chains attached to them. The scientists used a special chemical called phenylboronic acid to link gold n...

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-printing and 3D printing. Screen-printing is cheaper, but it's not ver...
