Formation and Properties of Self-Assembly-Driven Fluorescent Nanoparticle Sensors

Fluorescent nanoparticles (FNPs) are obtained in water by self-assembly from a polymeric ionic liquid, fluorescent carboxylate moiety, and a surfactant through two main supramolecular interactions, that is, ionic bonds and hydrophobic/hydrophilic interacti ...

Probing the Interaction Between a Surfactant-Cobalt(III) Complex and Bovine Serum Albumin

Hubert van den Bergh, Georges Wagnières

The mechanism of binding of the surfactant-cobalt(III) complex, cis-[Co(phen) 2(C 14H 29NH 2)Cl](ClO 4) 2{dot operator}3H 2O (phen = 1,10-phenanthroline, C 14H 29NH 2 = tetradecylamine) with bovine serum albumin (BSA) was investigated by UV-vis absorption, ...

PEG-b-PPS-b-PEI micelles and PEG-b-PPS/PEG-b-PPS-b-PEI mixed micelles as non-viral vectors for plasmid DNA: Tumor immunotoxicity in B16F10 melanoma

Eleonora Simeoni, Jeffrey Alan Hubbell, Melody Swartz, Susan Thomas

Cationic micelles formed from poly(ethylene glycol)-bl-poly(propylene sulfide)-bl-poly(ethylene imine) (PEG-b-PPS-b-PEI) and from mixtures of poly(ethylene glycol)-bl-poly(propylene sulfide) (PEG-b-PPS) with PEG-b-PPS-b-PEI were explored as non-viral vecto ...

Use of Simple Kinetic and Reaction-Order Measurements for the Evaluation of the Mechanism of Surfactant-Liposome Interactions

Surfactant liposome interactions have been previously studied through different methods and techniques. We present here a classical physical chemistry study on liposome solutions added to destabilizing agents at concentrations well above the solubilization ...

Rapid Access to Polyfunctional Lipids with Complex Architecture via Oxyanionic Ring-Opening Polymerization

Frederik Roman Wurm

Polymer-coated liposomes, particularly poly(ethylene glycol) (PEG)-substituted liposomes, have emerged as long-circulating carrier systems for drug delivery and diagnostic purposes. A rapid synthesis of three different types of multifunctional lipids with ...

Surface Structure of Sodium Dodecyl Sulfate Surfactant and Oil at the Oil-in-Water Droplet Liquid/Liquid Interface: A Manifestation of a Nonequilibrium Surface State

Sylvie Roke, Hilton Barbosa De Aguiar

We present sum frequency scattering spectra on kinetically stabilized emulsions consisting of nanoscopic oil droplets in water, stabilized with sodium dodecyl sulfate (SDS). We have measured the interfacial structure of the alkyl chains of the surfactant m ...

Ag-coverage-dependent symmetry of the electronic states of the Pt(111)-Ag-Bi interface: The ARPES view of a structural transition

Klaus Kern, Harald Brune, Marco Grioni, Alberto Crepaldi, Emmanouil Frantzeskakis

We studied by angle-resolved photoelectron spectroscopy the strain-related structural transition from a pseudomorphic monolayer (ML) to a striped incommensurate phase in an Ag thin film grown on Pt(111). We exploited the surfactant properties of Bi to grow ...

From an Epoxide Monomer Toolkit to Functional PEG Copolymers With Adjustable LCST Behavior

Frederik Roman Wurm

The lower critical solution temperature (LCST) behavior of novel poly(ethylene glycol) (PEG)-based copolymers bearing multiple functional groups, obtained by anionic ring-opening (co)polymerization (AROP), has been investigated. Variable comonomer ratios o ...
