Universidad de Alcalá-OTRI posted this:Antimicrobial electrospun fiber membrane with retention and controlled release capacity of active substancesResearchers from the Department of Analytical Chemistry, Physical Chemistry and Chemical Engineering of the University of Alcalá in collaboration with researchers from the Department of Chemistry and Physics of the University of Almería, presents a procedure for the manufacture of active membranes based on submicron fibers combining an antimicrobial action with the ability to retain apolar contaminants in aqueous solution. The membranes are produced by an electrospinning process in aqueous solution from mixtures of water soluble polyacids and polyols, which are subsequently stabilized by a thermal curing process and post-functionalized by the incorporation of amino-terminated dendrimers by a grafting process using a coupling agent. The material can be applied to the treatment of drinking water, to the regeneration of waste water, to the treatment of process waters and also to the controlled release of active substances, such as drugs, food preservatives, etc. The group seeks companies from the pharmaceutical, food, material technology and environmental sectors to sign technical cooperation agreements, commercial agreement with technical assistance and patent licensing agreements.

Biocompatible nanocapsules with liquid cores which enable effective encapsulation of hydrophobic compounds are stabilized without low molecular weight surfactants. These beneficial features significantly increase the range of possible applications.

RAMOT at Tel Aviv University Ltd. posted this:Molecular Electronics and Transistors based on Peptide NanostructuresProprietary peptide nanostructures can be readily fabricated on various surfaces including electrodes. A physical vapor deposition method (PVD) allows the precise control on the molecular dimensions of the structures using industry standard techniques. These nanostructures were used to fabricate metallic nanowires1 as well as trilayer metal-peptide-metal nano-cables. Electrodes and storages devices were modified with the peptide nanostructures. Recent work includes the application of the nanostructures to Ion-Sensitive Field-Effect Transistor (ISFET) with very strong responses measured, providing the basis for potential applications (to be published). The chemical nature of the building blocks allows the simple modification with various recognition elements. This could be readily modified to recognize DNA bases for sequencing purposes. The peptide structures are semi-conductive and possess various other unique physical properties (including mechanical rigidity, piezoelectric properties, non-linear optical properties, etc.).
