pH-responsive polymeric micelles (PM) consisting of random copolymers of N-isopropylacrylamide (NIPA), methacrylic acid (MAA), and octadecyl acrylate (ODA) were prepared and characterized. The critical aggregation concentration, as determined by a fluorescence probe technique, was approximately 10 mg/L in water and

Polymer microgels of poly(vinyl alcohol)/poly(methacrylate-co-N-isopropyl acrylamide) showed a thermoresponsive behavior, suitable for application in drug delivery (Biomacromolecules 2009, 10, 1589). In this work molecular dynamics (MD) methods were used to explain which structural aspects are determining for thermoresponsivity and how

New thermo-responsive, pH-responsive, and biodegradable nanoparticles comprised of poly(D,L-lactide)-graft-poly(N-isopropyl acrylamide-co-methacrylic acid) (PLA-g-P(NIPAm-co-MAA)) were developed by grafting biodegradable poly(D,L-lactide) onto N-isopropyl acrylamide and methacrylic acid. A core-shell type nano-structure was formed with a hydrophilic outer shell and a hydrophobic inner core

This work was focused on the investigation of temperature and pH-responsive polymeric composite membranes and their permeability to proteins and peptides in response to environmental stimuli. The composite membranes were prepared from nanoparticles of poly(N-isopropylacrylamide-co-methacrylic acid) of various NIPAAm:MAA ratios

We synthesized a temperature-responsive polymer, N-(isopropylacrylamide)-methacrylic acid copolymer, to which poly-l-lysine was introduced. The synthesized polymer as well as the parent polymer showed reversible soluble-insoluble changes in response to temperature changes across the lower critical solution temperature at 32 degree
