We report a procedure to grow thermo-responsive polymer shells at the surface of magnetic nanocarriers made of multiple iron oxide superparamagnetic nanoparticles embedded in poly(maleic anhydride-alt-1-ocatadecene) polymer nanobeads. Depending on the comonomers and on their relative composition, tunable phase transition

In this paper it is shown that when a thermosensitive hydrogel based on poly(N-isopropylacrylamide)-poly(ethylene glycol)-poly(N-isopropylacrylamide) (pNIPAm-PEG-pNIPAm) was transferred into water, flower-like micelles were continuously released as long as the medium was regularly refreshed. On the other hand, if the medium

Thermo-sensitive poly(N-isopropyl acrylamide-co-vinyl pyrrolidone)/chitosan [P(NIPAM-co-NVP)/CS] semi-IPN hydrogels with improved loading capacity and sustained release for anionic drugs NAP were prepared by free-radical polymerization. The LCST of hydrogels was adjusted to the vicinity of body temperature by introducing hydrophilic NVP. The

We report a novel approach for the fabrication of a photo-responsive surface with fast and reversibly switchable wettability between hydrophobicity and hydrophilicity induced by a photothermal effect.

Linear and miktoarm star-shaped diblock copolymers consisting of single-stranded DNA and poly(N-isopropylacrylamide) (PNIPAAm) with various compositions were synthesized via atom transfer radical polymerization and click chemistry. The temperature-responsive phase transition behavior, micellization, was systematically examined using UV-vis spectrometry, high-sensitivity differential

文章

Universal Platform for Surface Modification Employing Grafted Polymer Layers

The present publication focuses on synthesis and characterization of nanothick, chemically grafted polymer films (polymer brushes) on various inorganic and polymeric substrates.

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.
