Presentation Title: LOVE-FOOD: an integrated micro-nano-bio system for the detection of foodborne pathogens


The development of integrated, fast and affordable platforms for pathogen detection in food and other samples is an emerging area where a multidisciplinary approach is necessary for designing flexible micro/nano/bio systems; these new technologies promise a significant advancement of the current state of analytical testing leading to overall improved healthcare. In this EC-funded work, we have developed a lab-on-chip platform for the genetic analysis of Salmonella in milk samples. The system employs several innovations, including two plasma-etched plastic chips for bacteria capturing, lysis and nucleic acid purification; a micro-PCR module responsible for DNA amplification; and, an acoustic array-type biochip for DNA detection. All these modules are integrated in a credit-card size docking station where a microfluidic cartridge is used for sample processing. Automated, multiscale manipulation of fluids in complex microchannel networks is combined with novel sensing principles developed within the project. Current results show that a limit of detection of 5 bacteria can be reached through acoustic sensing without the use of labels while the total on-chip testing time is less than 2 hours. The system is expected to have a significant impact in food-pathogen detection by providing for the first time an integrated detection test for Salmonella screening in a very short time. Finally, thanks to the low cost and compact technologies involved, the proposed set-up is expected to provide a competitive analytical platform for direct application in field settings.
