AB  - We report a new strategy for synthesizing temperature-responsive 
      gamma-Fe(2)O(3)-core/Au-shell nanoparticles (Au-mNPs) from diblock copolymer 
      micelles. The amphiphilic diblock copolymer chains were synthesized using 
      reversible addition-fragmentation chain-transfer (RAFT) with a thermally 
      responsive "smart" poly(N-isopropylacrylamide) (pNIPAAm) block and an 
      amine-containing poly(N,N-dimethylaminoethylacrylamide) (DMAEAm) block that acted 
      as a reducing agent during gold shell formation. The Au-mNPs reversibly 
      aggregated upon heating the solution above the transition temperature of pNIPAAm, 
      resulting in a red-shifted localized surface plasmon resonance.
