Structural and rheological investigation of Fd3m inverse micellar cubic phases
Liquid crystalline phases (bicontinuous cubic, reversed hexagonal, lamellar) can be made easily from food emulsifiers such as monoglycerides. Recently we explored in detail the formation of an inverse discrete micellar Fd3m cubic phase, which usually [...]
Modulation Of Nanochannels Hydration In Lipid Cubic Phases Studied by SANS and SAXS
Angelov B., Angelova A., Angelova A., Garamus V., Lebas G., Funari S., Lesieur S., Ollivon M., Couvreur P., CNRS UMR8612, FR
The hydration of a bicontinuous lipid cubic phase, respectively the sizes of the aqueous nanochannels formed in such a supramolecular structure of hydrated monoolein, was modulated by incorporation of small nonionic guest molecule (octyl glucoside). [...]
Nanoassemblies from Vitamin C Derivatives
Lo Nostro P., Ambrosi M., Fratini E., Ridi F., Carretti E., Alfredsson V., Ninham B.W., Baglioni P., University of Florence, IT
Two new amphiphilic derivatives of Vitamin C were synthesized. These molecules keep the same antioxidant activity of Vitamin C, but are soluble also in hydrophobic media. They produce nanoassemblies and organogels. We report here a [...]
A New Route to the Formation of Nanoporous Capsules using Block Copolymer Thin Films & Colloids
The objective of this project is the preparation of novel porous nanocapsules. Spherical colloidal particles, such as melamine formaldehyde (MF), are coated with a mixture of a multilayer of diblock copolymers/micelles and polymer coated Au [...]
Smart Silver Nanoparticles from Nanoreactors made by Invertible Polyesters
A simple way to prepare uniform amphiphilic silver nanoparticles in concentrated solutions of an invertible polyester is developed. The mobility of polymer fragments increases by dissolving of the polyester in benzene. Experimental data show that [...]
Gold Nanoparticle Super Assembly by Dielectrophoresis
Dielectrophoretic assembly of nanoparticles has great utility in creating intricate designer nanoscale structures. Despite their utility, little is known about the mechanisms that govern different assembly morphologies. The magnitude and frequency of the applied field, [...]
Formation of Giant Unilamellar Vesicles from Block Copolymers and Study of AqpZ and KvAP Protein Incorporation with Light Microscopy
We have formed giant unilamellar vesicles (GUV’s) using two types of block copolymers—PMOXZ-PDMS-PMOXZ triblock and PBD-PEO diblock—and studied incorporation of labeled, transmembrane proteins using aquaporin (AqpZ), a water channel protein, and KvAP, a voltage-gated potassium [...]
Bio-inspired Polymers for Nanoscience Research
Peptoids are a novel class of non-natural biopolymer based on an N-substituted glycine backbone that are ideally suited for nanomaterials research. This bioinspired material has many unique properties that bridge the gap between proteins and [...]
Soft Structured Piezoresistive Sensors by Inkjet Printing
In this communication, we present a novel approach for the fabrication of soft structured polymeric strain sensors composed of, woven cotton base, and a conducing poly (3, 4 – ethylenedioxythiophene) - poly (4-styrenesulfonate) (PEDOT/PSS). A [...]
Controlling the Surfaces of Food: Self-Assembly of Biopolymers
DuraFizz develops and applies nanotechnology-inspired innovations to the food industry by controlling the spontaneous self-assembly of biopolymers at surfaces. This principle is demonstrated in several current research projects including nutrient encapsulation, edible foams, and fryer [...]
Vibrational spectroscopy of nanoscale needle shaped histamine
Amino acids in aqueous solutions have low Raman signals and are difficult to detect at low concentrations. To increase Raman signals one often uses UV excitation. We find that nano-needels can be grown from droplets [...]
