Producing synthetic soft worm and rod structures with multiple chemical functionalities on the surface would provide potential utility in drug delivery; nanoreactors; tissue engineering; diagnostics; rheology modifiers; enzyme mimics; and many other applications. Here; we have synthesized multifunctional worms and rods directly in water using a one-step reversible addition-fragmentation chain transfer (RAFT)-mediated dispersion polymerization at high weight fractions of polymer (>10 wt %). The chain-end functionalities included alkyne; pyridyl disulfide; dopamine; β-thiolactone; and biotin groups. These groups could further be converted or coupled with biomolecules or polymers. We further demonstrated a nanorod colorimetric system with good control over the attachment of fluorescent probes. © 2014 American Chemical Society;
