One-Step Immunoassay for Biomarker Quantification in Complex Mixtures Based on Phase-Separated Antifouling Coacervates.

Summary: Imagine trying to find a specific person in a massive, crowded stadium. It would take forever! Scientists have created a new tool called "oneSTEP" that acts like a microscopic VIP magnet. It pulls the exact disease markers (like signs of a virus) out of messy bodily fluids like spit or blood. The best part? It does this in just one step without needing to wash away the "crowd" of other stuff. This fast, glowing test could make diagnosing diseases much quicker and easier in the future.
