TIDAL: Target-Induced Droplet Assembly of Ligands

Developed by Los Alamos National Laboratory, TIDAL (Target-Induced Droplet Assembly of Ligands) transforms the small antibody fragments known as nanobodies into a programmable, protein-only material that organizes itself on demand. By harnessing a natural process called liquid-liquid phase separation, TIDAL lets these binders gather into dense, dynamic droplets precisely when they encounter their intended target, giving developers a single platform that can purify proteins without costly resins, deliver drugs as a self-forming slow-release depot and even trap harmful proteins inside living cells. The outcome is a versatile toolkit that lowers production costs, simplifies manufacturing and opens fresh therapeutic and diagnostic possibilities, all from a building block that biology already k
