To improve its poor aqueous solubility and stability, the potential chemotherapeutic drug quercetin was encapsulated in soluplus polymeric micelles by a modified film dispersion method. With the encapsulation efficiency over 90%, the quercetin-loaded polymeric micelles (Qu-PMs) with drug loading of 6.7% had a narrow size distribution around mean size of 79.00 ± 2.24 nm, suggesting the complete ...

in this study, poly(ethylene-co-vinyl alcohol) (evoh) as a novel biocompatible polymeric scaffold was surface modified by succinylation to get evohs and further pegylated to improve structural properties using methoxypolyethylene glycol (5000 da) succinate (pegs) along with targeting with retinoic acid (ra) to get final modified active and passive targeted conjugate (pegs-evohs-ra) to evaluate ...

Recent experimental studies on the rheology of block copolymer micelles are reviewed. Where appropriate, we draw analogies between the viscoelastic properties of polymeric micelles and those of colloidal dispersions. We also present some important differences between these two classes of complex fluids, namely the ability to tune self-assembly through solvent polymer interactions. Finally, new ...

Curcumin, a poorly water-soluble bioactive compound, was successfully loaded into three different aromatic contents of hydroxypropylmethacrylamide (HPMA)-based polymeric micelles in order to develop water-soluble curcumin nanoformulations (Cur-Nano). The stability study of Cur-Nano was done by keeping the formulations at 4, 30, and 40 °C for 90 days. The physical appearance, curcumin remaining,...

A series of monomethoxy poly(ethylene glycol)-poly(lactide) (mPEG-PLA) diblock copolymers were synthesized, and mPEG-PLA micelle was fabricated and used as a nanocarrier for solubilization and delivery of a promising anticancer drug ethaselen. Ethaselen was efficiently encapsulated into the micelles by the dialysis method, and the solubility of ethaselen in water was remarkably increased up to ...

A variety of polymeric nanoparticles have been developed for bioimaging applications. This study reports on the use of a 50 nm recombinant protein nanoparticle with a multivalent surface as a vehicle for functionalization with a model imaging agent. Multiple fluorescent probes were covalently conjugated to surface amines of crosslinked amphiphilic elastin-mimetic protein micelles using N-hydrox...

In this study, we report the assembly of amphiphilic polymeric micelles at the liquid/air interface to prepare liquid marbles for the first time. The polymeric micelles were synthesized from the self-assembly of a fluoropolymer, poly(styrene-co-acrylic acid-co-2,2,3,4,4,4-hexafluorobutyl methacrylate), in a selective solvent. The particle size, morphology and chemical composition of the micelle...

A new type of voltage-responsive comb-like superamphiphilic block polymer PEG113-b-PAA30/FTMA was prepared by the electrostatic interactions of an ionic ferrocenyl surfactant (FTMA) and an oppositely charged double-hydrophilic block polyelectrolyte poly-(ethylene glycol)-b-poly(acrylic acid) (PEG113-b-PAA30) in aqueous solution. An in situ electrochemical redox system was designed to research i...

Polymeric micelles supply an environment, which can be cautiously regulated for drug delivery. The self-assembly of polymeric micellization is dynamic. Micellization thermodynamic describes how the system defines formation micelles. present study enables behavior surfactants in presence polymer to examined by conductometric and tensiometric methods. effects concentration temperature on thermody...

Two types of turbidimetric detection of adenosine 5'-triphosphate (ATP) by the naked eye were achieved through a combination of non-cross-linking aggregation of DNA-linked polymeric micelles and molecular recognition of ATP by a DNA aptamer.
