The diagnosis and management of acute Sepsis is a critical area where fast and accurate results can translate into life changing health outcomes for individuals. The overall aim of RAIS is to develop a new point-of-care label-free microarray platform and validate it for quantifying levels of specific Sepsis’ biomarkers. The approach uses a novel interferometric technique ultimately capable of providing very large arrays of tests. Specific objectives and activities include: (i) an optical microarray reader based on a disruptive proprietary design combining interferometric lens-free microscopy and proximity CCD or CMOS image sensing; (ii) a microarray plate, in a proper microfluidic cartridge, consisting of a transparent slide with a novel nano-structured surface geometry to increase the detection sensitivity and covered by specific receptors to capture bio-markers; (iii) their integration in a portable and battery powered label free microarray platform potentially capable of measuring more than 1 million bio-targets simultaneously. The developed technology will be capable to detect microribonucleic acids (microRNAs), interleukins and other specific proteins associated to Sepsis using a few microliters of blood or serum samples, in a concentration of a few pg/ml, within 30 minutes (sample to result) and at a cost per patient of less than 50€. In this way, patients will be put on the right treatment more rapidly, potentially reducing the Sepsis mortality rate of more than 70%, with estimated cost savings of more than €10 billion per year as a consequence of shorter hospital stays, reduced use of unnecessary drugs and lower associated insurance bills.
