Microdevices are also explored to observe microbial and mammalian cells behavior aiming at the determination of kinetic growth parameters, development of systems for drug screening and new strategies for biological in vitro models.

Talk title: "Microfluidics applied to Nano, Micro and Biotechnology"


Microfluidics is a multidisciplinary field that operates at the microscale with small amount of fluids. The hydrodynamic characteristics allow the control of chemicals, cells, lipids, and nucleic acids in space and time. Therefore, microfluidics enables applications that would not be feasible at the macroscale and this platform demonstrates high potentiality as a tool for in vitro cell culture, biological models, drug research, synthesis of nanomaterials and microencapsulation. The microenvironment uses few amounts of sample and reagents that flows in microchannels in the laminar regime since no external force is applied. In this case, the micron scale minimizes effects of mass and heat transfer, allowing integration of different techniques for data acquisition in different ways than macro scale. These characteristics open great opportunities for technological research in the fields of Micro/Nano & Biotechnology. This presentation will explore different applications of microfluidics in the field of Micro/Nano & Biotechnology.

Rossana Madrid is EE and Ph.D. in Bioengineering. She is currently Full Professor of Biomedical Transducers and Biosensors and Microsystems of the Biomedical Engineering Program, and also at the Doctoral degree, at the Faculty of Science and Technology at the University of Tucumán, Argentina. She is Independent Researcher at the National Council of Scientific and Technical Investigations of Argentina (CONICET). She has published R&D papers in national and international journals, two chapters in books and has developed two patents. She leads research grants and international cooperation grants with two German Universities. She leads graduate and postgraduate theses in the area of biosensors and microfluidics. Her main research fields include sensors and biosensors, microfluidic systems and paper-based POC (Point of care) devices for biomedical and environmental applications. Particularly, her microfluidic group is working now in the development, from one side, of a microfluidic paper POC device for the detection of Leishmaniasis in cooperation with the Experimental Pathology Institute of Salta, and on the other hand, of hybrid microfluidic chips. For the latter case, the incorporation of active elements (peristaltic pumps, valves, etc.) made with stimulus-sensitive hydrogels for fluid management, is evaluated. In the area of biosensors, her group won in February 2019, the Eukera prize to make the field validation of a biosensor for the early detection of HuangLongBing disease (HLB) in citrus plants.

Sorin Melinte is Professor of Electrical Engineering in the Institute of Information and Communication Technologies, Electronics and Applied Mathematics at Université catholique de Louvain, Belgium. His current projects aim at developing novel nano- and micro-devices and hybrid inorganic-organic platforms for molecular electronics as well as scaffolds for bioelectronics and additive manufacturing via microfluidics. In particular, he uses high-resolution electron-beam nanolithography and soft-lithography to link bottom-up and top-down nano- and micro-structuring techniques for the engineering of smart materials.

Talk title: "Novel electro-optic techniques and nano-engineered transparent materials for microfluidics"


Designed with targeted properties and combining multiple attributes that allow them to be dynamic, ordered particle assemblies are strong candidates to replace the traditional structures processed with top-down fabrication approaches. Self-assembly by gravitational sedimentation is one of the methods largely used to organize particles in desired architectures. Understanding the physical phenomena that take place during self-assembly is a crucial step in controlling the structure and properties of the colloid-designed materials. In this respect, novel approaches to analyse the spatial and temporal information embedded in colloidal systems confined to microfluidic environments are needed.

Interestingly, coplanar waveguides can be used to study the physical phenomena that appear during gravitational sedimentation due to their unique response towards the dielectric properties of the surrounding environment. Microwave measurements using coplanar waveguides were reported for fluidic environments, with a focus on the dielectric characteristics of liquid samples. Various other electro-optic techniques and devices were designed at microwave frequencies to measure dielectric properties of biomaterials or analyte concentrations in microfluidic systems: coaxial probes, microstrip transmission lines or microwave resonators. We employ coplanar waveguides and simple microfluidic structures to study the on-chip sedimentation of polystyrene nano- and micro-spheres in aqueous solutions. Along with the detection of the solution's concentration, we monitor the time evolution of the underlying sedimentation processes and we devise a technique applicable to the specific detection of molecular species. We present a novel class of biosensing devices, based on coplanar waveguides fabricated onto thin glass and working in the frequency interval from 40 MHz to 40 GHz.

Finally, we discuss further integration of coplanar waveguides within lab-on-chip technologies. We address nano-engineered transparent electronics and the exploitation of complex circuitry for enhanced real-time monitoring of target analytes as well as for surveying soft matter self-assembly in various microfluidic environments.
