Neopterin, or NPT, is a crucial signal in the body's immune response. It plays a big role in spotting and keeping an eye on various health issues. Scientists have come up with a new way to measure NPT in human blood and a lab-made fluid that mimics what's in our spinal cord. They used a special material called magnetic silica-supported molecularly imprinted polymer, ...

A new method has been developed to measure human albumin in different body fluids. This method uses magnetic beads that have been modified with a special molecule called H8 aptamer. These beads can bind to human albumin and change how they clump together. This clumping can be seen with the naked eye and even measured using a smartphone. The more albumin there is, the...
