Drug Deliv.Photo- and thermo-responsive multicompartment hydrogels for synergistic delivery of gemcitabine and doxorubicin.The process of free radical polymerization of a single type of monomer, in this case, N -isopropylacrylamide, to form the polymer is known as a homopolymerization.Poly(N-isopropylacrylamide) (variously abbreviated PNIPA, PNIPAAm, NIPA, PNIPAA or PNIPAm) is a temperature-responsive polymer that was first synthesized in the 1950s.
The water molecules must reorient around the nonpolar regions of PNIPA which results in a decreased entropy.The radical initiator azobisisobutyronitrile (AIBN) is commonly used in radical polymerizations.
It is synthesized via free-radical polymerization and is readily functionalized making it useful in a variety of applications.The reaction scheme below is a terpolymerization to form a cross-linked hydrogel.Journal of Pharmaceutical Sciences, pharmacokinetics,. 25 Schmaljohann, D.Biodegradable and pH responsive. thermo responsive hydrogels are a.Innovative drug delivery technologies based on smart hydrogels. glucose- and pH-responsive on-off. dependent transition of such thermo-responsive polymers.What links here Related changes Upload file Special pages Permanent link Page information Wikidata item Cite this page.Abstract Stimuli-responsive polymers show a sharp change in properties upon a small or modest change in environmental condition, e.g. temperature, light, salt.In medicine, stimuli-responsive polymers and hydrogels have to show their response properties within the setting of biological conditions, hence there is a large.
