Abstract:

Thermoresponsive poly(N-isopropyl acrylamide) (pNIPAm) microgels possessing a hollow structure have been synthesized from core-shell nanoparticles upon oxidation of the particle core, followed by removal of the produced polymer segments by centrifugation. N,N'-(1,2-dihydroxyethylene)bisacrylamide (DHEA) is used as a cross-linker for preparing the degradable core, whereas N,N'-methylenebis(acrylamide) (BIS) is used as a cross-linker to add a nondegradable pNIPAm shell. Addition of NaIO(4) to a suspension of these particles in water leads to controlled degradation of the particle core by cleavage of the 1,2-glycol bond in DHEA. Fluorescence spectroscopy, UV/Vis spectroscopy, and photon correlation spectroscopy are used to characterize the hollow particles produced.
