An ultrasensitive sensor for rapid detection of micro-organisms such as viruses and bacteria, and biomarkers has been developed at the MESA+ Institute based on a Lab-on-a-Chip Interferometric Nanotechnology. This sensor has been quoted by Forbes.com as one of the “ 13 Amazing New Nanotechnologies ” worldwide! The essential innovation in this technique is the combination of an integrated optics interferometric sensor with antibody-antigen recognition approaches. The sensor basically consists of a laser, which is shone through an optical chip on which several measuring and reference channels are located . To spot a particular virus (or any other analyte), the appropriate antibodies are immobilized onto one of the measuring channels and then a sample containing the virus is flowed through that channel. If the virus particles bind to the antibodies, the interference pattern of the light, which is recorded on a CCD camera, changes, allowing estimation of the concentration. The sensor is able to spot the Herpes virus at concentrations of just 850 particles per milliliter under physiological conditions in a few minutes. The sensitivity of the sensor approaches detection of a single virus particle, yielding a sensor of unprecedented sensitivity with wide applications for viral diagnostics. Detection of other types of viruses, bacteria, cells and biomarkers in complex mediums has been performed as well. The technology is amenable to miniaturization and mass-production, and thus has significant potential to be developed into a handheld, point-of-care device.
Based on this nanotechnology, Ostendum - a new spin-off of the MESA+, has developed a prototype, consisting of a Lab-on-a-Chip system and a portable Detector. Working principle of such a prototype is schematically shown in this slide: First, a sample such as blood, serum, saliva, etc., is delivered to the pre-coated chip; Next, the chip is inserted into the portable detector and an automated analysis will be started; In a few minutes, via an easy-to-handle user interface, the type of analyte such as virus, bacteria, biomarker, etc., and respective concentration will be provided. This Lab-on-a-Chip sensor device has potential applications in medical diagnostics, food and water safety, security applications, environmental monitoring, animal and plant health monitoring, etc.
