IK4 develops a portable device for detecting Salmonella in under an hour
Date:1/22/2009

This release is available in Spanish.

IK4 Technological Alliance has designed a low-cost, rapid diagnostic device for detecting the presence of Salmonella spp. and other bacteria in less than one hour, a much shorter time than current systems. Unlike others, this project used clinical samples directly, without prior treatment in a laboratory.

The new diagnostic device is effectively a miniature conventional laboratory inside a chip (Lab on a Chip) (see photograph). Moreover, it is highly specific, rapid, portable and user-friendly. In this way, an ample range of possible users -hospitals, health centres and the food industry, amongst others have available a device equipped with an optical reading system (fluorescence signal emitted during Polymerase Chain Reaction (PCR) reaction in real time), that enables the rapid identification of pathogens. Within the Chip the system integrates the concentrating of the sample, the rupture of its membrane, the enzymatic multiplication of its DNA and finally identification of the pathogen. The user only has to insert two syringes into the device and the analysis is undertaken automatically.

This research is within the remit of the European OPTOLABCARD project, launched in September 2005 and now about to finish. The project is led by IKERLAN-IK4 and financed by the VI Framework Programme, with an overall budget of 2.9 million euros, and involving the participation of a total of 9 different bodies DTU-Nano, the Hospital de Donosti through the BIOEF Foundation and GAIKER-IK4 itself, amongst them and from 6 different countries (Germany, Austria, Denmark, Spain, Poland and Sweden).

GAIKER-IK4's participation in the project has focused on the adaptation of biochemical developments to the microfluid system of the chip, as well as the optimisation and characterisation of the device f
