homopolymers of N-vinylcaprolactam and graft copolymers of N-vinylcaprolactam and poly(ethylene oxide)−alkyl methacrylate macromonomer were synthesized with different amounts of hydrophobic fluorescent labels, pyrene, and naphthalene. Association of the polymers in dilute aqueous solutions was studied below and above the LCST using dynamic light scattering, microcalorimetry, and various fluorescence spectroscopy

liberates iron oxide nanoparticles. This allows the utilization of imaging agents as tracers of the hydrogel degradation. UV–vis spectrometry and MRI studies reveal that the degradability of the hydrogels correlates with their structure. The hydrogels presented here are very promising theranostic tools for hyaluronidase‐mediated delivery of hydrophobic drugs, as well as imaging of hydrogel degradation
