Hydrogen peroxide-responsive micelles self-assembled from a peroxalate ester-containing triblock copolymer.
A novel ABA triblock copolymer by using peroxalate esters as linkages was synthesized. In water, this amphiphilic copolymer self-assembled into micelles which were used as drug delivery carriers. When stimulated with hydrogen peroxide, the micelles disassembled to release drugs since the responsive peroxalate ester linkages would be cleaved after the reaction with hydrogen peroxide.
متن کاملCharacterization of the core-shell nanoparticles formed as soluble hydrogen-bonding interpolymer complexes at low pH.
The formation of soluble hydrogen-bonding interpolymer complexes between poly(acrylic acid) (PAA) and poly(acrylic acid-co-2-acrylamido-2-methyl-1-propane sulfonic acid)-graft-poly(N,N-dimethylacrylamide) (P(AA-co-AMPSA)-g-PDMAM) at pH=2.0 was studied. A viscometric study showed that in semidilute solution a physical gel is formed due to the interconnection of the anionic P(AA-co-AMPSA) backbon...
متن کاملGiant tubular and toroidal vesicles from self-assembled triblock copolymer-polyaniline complexes in water.
An ABA type amphiphilic triblock copolymer was synthesized via ATRP and sulfonation. New self-assembled morphologies such as toroidal vesicles, giant tubular vesicles, and perforated spherical vesicles were observed from triblock copolymer-polyaniline complexes in water. The mechanism of morphology transformation at different compositions was discussed.
متن کاملModulating water-exchange rates of lanthanide(III)-containing polyaminopolycarboxylate-type complexes using polyethylene glycol.
We have synthesized a series of Ln(III)-containing polyethylene glycol conjugates and studied the structural and electronic properties of these complexes. These studies demonstrate that polyethylene glycol can be used to fine-tune water-exchange rates of Ln(III)-containing polyaminopolycarboxylate-type complexes; this control is desirable in developing Ln(III)-containing contrast agents for mag...
متن کاملSynthesis, characterization, and computational study of complexes containing Pt···H hydrogen bonding interactions.
Complexes [Pt(C6F5)(bzq)L] (bzq = 7,8-benzoquinolinate; L = 8-hydroxyquinoline, hqH (1); 2-methyl-8-hydroxyquinoline, hqH' (2)) have been prepared by replacing the labile acetone ligand in the starting material [Pt(C6F5)(bzq)(Me2CO)]. The (1)H NMR spectra of 1 and 2 show that the signals attributable to the hydroxyl proton of the hqH or hqH' ligands are displaced downfield 2.64 ppm for 1 and 2....
