Supramolecular reverse micelle assemblies, formed by amphiphilic copolymers, can selectively encapsulate molecules in their interiors depending on the functional groups present in the polymers. Altering the binding selectivity of these materials typically requires the synthesis of alternate functional groups. Here, we demonstrate that the addition of Zr(IV) ions to the interiors of reverse mice...

The shell cross-linked (SCL) thermoresponsive hybrid poly(N-isopropylacrylamide-co-aminoethyl methacrylate)b-polymethyl methacrylate (P(NIPAAm-co-AMA)-bPMMA) micelle consisting of a cross-linked thermoresponsive hybrid shell and a hydrophobic core domain was fabricated via a two-step process: micellisation of P(NIPAAm-co-AMA)-b-PMMA in aqueous solution followed by cross-linking of the hydrophil...

zno and zno:mn nanocrystals synthesized via reverse micelle method. the size, band gap, urbach energy, optical constants and penetration depth of nanocrystals were calculated by uv-vis spectroscopy data. the surface morphology was studied with the use of scanning electron microscope (sem). moreover the samples exposed to gama ray source of 60co and their thermoluminescence properties were also ...

In this work, the naturally occurring -hairpin antimicrobial peptide protegrin-1 (PG-1) is studied by molecular dynamics simulation in all-atom sodium dodecylsulfate and dodecylphosphocholine micelles. These simulations provide a high-resolution picture of the interactions between the peptide and simple models of bacterial and mammalian membranes. Both micelles show significant disruption, as i...

With the increasing use of wormlike micelle solutions as rheological modifiers in many consumer products, the prediction of the behavior of these fluids has grown increasingly important in recent years. In this paper, the flow past a sphere falling at its terminal velocity through a column of a wormlike micelle solution is experimentally studied. The working fluid is an entangled wormlike micel...

Novel biomimetic surfactants based on cholesterol as the hydrophobic segment and poly[2-(methacryloyloxy)ethyl phosphorylcholine] (pMPC) as the hydrophilic segment were synthesized in the present study by atom transfer radical polymerization (ATRP) of 2-(methacryloyloxy)ethyl phosphorylcholine (MPC) using a cholesterol-based macroinitiator. The association behavior of cholesterol-block-poly[2-(...

The N-terminal fusion domain of the HIV-1 gp41 envelope glycoprotein is responsible for initiating the fusion of viral and cellular membranes, leading to the subsequent infection of the host cell by HIV-1. We have investigated the backbone structure and dynamics of the 30 N-terminal residues of HIV-1 gp41 in membrane-mimicking environments using NMR spectroscopy and (15)N- and (15)N,(13)C,(2)H-...

Stimuli-responsive self-assembly is playing an increasingly important role in emerging applications, ranging from smart materials to biosensors. However, obtaining essential information for further development, such as molecular arrangement and interaction, is still experimentally challenging. A molecular-level understanding of the stimuli-responsive self-assembly is needed. Azobenzene-containi...

Electrophoretic inks, which are suspensions of colorant particles that are controllably concentrated and dispersed by applied electric fields, are the leading commercial technology for high-quality reflective displays. Extending the state of the art for high-fidelity color in these displays requires improved understanding and control of the colloidal systems. In these inks, reverse micelles in ...

The purpose of drug delivery systems in cancer chemotherapy is to achieve selective delivery of anti-cancer agents to cancer tissue at an effective concentrations for the appropriate duration of time, so that we may be able to reduce the adverse effects of a drug and simultaneously enhance the anti-tumor effect. Polymeric micelles were expected to increase the accumulation of drugs in tumor tis...
