Abstract:
There is a high demand to develop innovative and cost effective devices with interest for health care beside environment diagnostics, safety and security applications. The development of such devices is strongly related to new materials and technologies being nanomaterials and nanotechnology of special role. We study how new nanomaterials such as nanoparticles, graphene, nano/micromotors can be integrated in simple sensors thanks to their advantageous properties. Beside plastic platforms physical, chemical and mechanical properties of cellulose in both micro and nanofiber-based networks combined with their abundance in nature or easy to prepare and control procedures are making these materials of great interest while looking for cost-efficient and green alternatives for device production technologies. Both paper and nanopaper-based biosensors are emerging as a new class of devices with the objective to fulfil the “World Health Organization” requisites to be ASSURED: affordable, sensitive, specific, user-friendly, rapid and robust, equipment free and deliverable to end-users. How to design simple paper-based biosensor architectures? How to tune their analytical performance upon demand? How one can couple nanomaterials such as metallic nanoparticles, quantum dots and even graphene with paper and what is the benefit? How we can make these devices more robust, sensitive and with multiplexing capabilities? Can we bring these low cost and efficient devices to places with low resources, extreme conditions or even at our homes? Which are the perspectives to link these simple platforms and detection technologies with mobile communication? I will try to give responses to these questions through various interesting applications related to protein, DNA and even contaminants detection all of extreme importance for diagnostics, environment control, safety and security.
Bio:
After his PhD (1991) at Tirana University, in the topic of Ion-Selective-Electrodes (ISEs) designs and applications in clinical and environmental analysis, Dr. Merkoçi worked as postdoc at other European research centres and USA in the field of nanobiosensors and lab-on-a-chip technologies. His postdoc periods were followed by leading positions in several laboratories: (1997-2006) at Autonomous University of Barcelona and since 2006 at Institut Català de Nanociencia i Nanotecnologia ICN2.
Prof. Merkoçi's research is focused on the design and application of cutting edge nanotechnology and nanoscience-based biosensors. These nanobiosensors are based on the integration of biological molecules (DNA, antibodies, cells and enzymes) and other (bio)receptors with micro- and nanostructures and applied in diagnostics, environmental monitoring or safety and security. He has published around 270 peer review research papers, is editor of books (“Nanomaterials Based Biosensing Systems, by Wiley; “Electrochemical Sensor Analysis”, of Comprehensive Analytical Chemistry series by Elsevier etc.), book chapters and special journals issues (Lab on a Chip, Electroanalysis, Microchimica Acta) dedicated to the field of nanomaterials integration and applications in biosensors.
