The design and synthesis of responsive polymer brushes and their applications in nanotheranostics. Responsive polymer brush‐based materials can be designed and synthesized via surface‐initiated controlled radical polymerization initiated from various substrates and cores with desired responsiveness and architecture for the applications in biosensing, diagnosis and as smart drug delivery systems.
