Direct On-chip Storage and Release of Liquid Reagents for Diagnostic Lab-on-a-Chip Devices
Daniel Czurratis*, Thomas Brettschneider*, Yvonne Beyl*, Sven Zinober*, Franz Lärmer*, Roland Zengerle**

We present a direct on-chip storage and release of liquid reagents for diagnostic lab-on-a-chip devices. Reagent release is pressure driven and realized by braking up a barrier film through a deflection of a flexible membrane.

Polymerized Poly(ethylene glycol) Diacrylate Microfluidic Membrane Valves
Chad I. Rogers, Joseph B. Oxborrow, Long-Fang Tsai, Gregory P. Nordin, and Adam T. Woolley

Polymerized poly(ethylene glycol) diacrylate (poly-PEGDA) was fabricated into pneumatically controlled, non-elastomeric membrane valves as a nonspecific adsorption resistant alternative to polydimethylsiloxane valves. Temporal response, valve closure, and long-term durability of these poly-PEGDA valves were evaluated.

ChemoSoft: a new chemometric software for non-chemometricians
Christophe B.Y. Cordella

Professional applications such as those provide by some software editors and free downloadable toolboxes developed for Matlab®, R, Octave or Scilab propose many computation tools. But, to our best knowledge, very few are usable by neophytes or anyone that are not skilled with chemometrics or statistics. ChemoSoft is the first chemometric software designed for non-chemometricians.

Chemometrical optimization and fast determination of debittering of table olives by means of capillary electrophoresis
Albillos SM, Busto MC, Ortega N, Pilar-Izquierdo MC, Ramos-Gómez S, Pérez-Mateos M

Table olives require a thorough process of debittering in order to achieve the organoleptic quality of olives before consumption. Capillary electrophoresis offers several advantages to the determination of the bitter responsible compound oleuropein in table olives, such as speed, reduced amount of solvents and reagents, small amount of sample, high efficiency and lower costs.

Identification and classification of antifouling compounds secreted by anti MIC microorganisms. A metabolomic analysis.
Albillos SM; Balaña-Fouce R; Montero O; Barreiro-Mendez C; Blas-Galindo E; Barros-García R; Guedella-Bustamante E; Ullán RV

BIOCORIN project, aims to develop a green alternative to the coatings and solutions used up to date for MIC corrosion control. Some of the results of this project are presented here, with the identification of several relevant antifouling compounds secreted by environmentally isolated anti-MIC strains of microorganisms via a metabolomic approach.
