Tannic acid-coated magnetic beads could facilitate early cancer diagnosis

Researchers have synthesized tannic acid-coated magnetic beads capable of extracting membrane vesicles called "exosomes" from biological fluids with 60% efficiency. This novel method will make it easier and faster to isolate exosomes from laboratory samples, while the chemical composition of the exosomes will help detect cancer in its early stages. The study was published in the Journal of Materials Chemistry B.
