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

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

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

The loading of an antihypertensive cationic drug, diltiazem hydrochloride (DIL.HCl), into poly(N-isopropylacrylamide) [P(N-iPAAm)], poly(methacrylic acid) [P(MAA)], and their poly[(N-isopropylacrylamide)-co-(methacrylic acid)] P[(N-iPAAm)-co-(MAA)] hydrogels as well as their release behaviour have been investigated. For this purpose, two series of hydrogels have been

In this study, we report a new controlled release system based on up-conversion luminescent microspheres of NaYF(4):Yb(3+)/Er(3+) coated with the smart hydrogel poly[(N-isopropylacrylamide)-co-(methacrylic acid)] (P(NIPAM-co-MAA)) (prepared using 5 mol % of MAA) shell. The hybrid microspheres show bright up-conversion fluorescence

Articles

Poly(N-isopropylacrylamide), or PNIPAM, is a stimuli-responsive polymer that responds to changes in pH and temperature and has a LCST around 32 C.

Tissue engineering has become a key therapeutic tool in the treatment of damaged or diseased organs and tissues, such as blood vessels and urinary bladders.

By altering the physicochemical properties, smart or intelligent drug delivery systems can be designed to deliver therapeutic molecules on-demand. Learn more about the application of stimuli-responsive materials in drug delivery.

Professor Mitsuhiro Ebara provides insights on several types of smart nanofiber mesh systems that have been explored for different drug delivery purposes.
