Lima is Associate Professor at the Department of Mechanical Engineering, University of Minho (UMinho), and Researcher at the Mechanical Engineering and Resource Sustainability Center (MEtRICs, UMinho) and Transport Phenomena Research Center (CEFT), FEUP, University of Porto. His research is mostly centered on the area of microfluidics, nanofluidics, and blood flow in biomedical microdevices. Currently, he lectures as part of several Master courses in Mechanical and Industrial Engineering. In the past, he has delivered lectures as part of several Master courses in Biomedical Technology, including Cardiovascular Biomechanics and Micro/Nanotechnologies and Biomedical Applications at the Braganc¸a Polytechnic Institute (IPB). Currently, he also supervises several PhD and Master students in the field of Mechanical and Biomedical Engineering. Grac¸a Minas is Associate Professor and Deputy Director at the Department of Industrial Electronics, as well as Researcher at the CMEMS-UMinho (Center for Microelectromechanical Systems), University of Minho, Portugal. Her research is mostly centered on the area of biomedical microdevices, specifically, in lab-on-a-chip integration of electronic circuits, optical filters, solid-state integrated sensors, biosensors, and actuators in those LOC devices. She is also developing organ-on- a-chip systems that aim to mimic human responses to various chemicals in vitro. She has published more than 130 articles and 7 patents. She supervised 2 postdoctoral fellows, 11 PhD theses (7 finished), 40 Master theses, and numerous research fellows (in the scope of project grants). Furthermore, she has participated in 18 national and European projects and has been Principal Investigator in 8 of them (6 completed). Susana Catarino received her PhD degree in Biomedical Engineering in 2014 from the University of Minho, Portugal. She is currently Researcher at the Center for Microelectromechanical Systems (CMEMS-UMinho) at the same University. From October 2016, she was also Visiting Assistant Professor at the same institution, lecturing at the Dept. of Industrial Electronics in the areas of Modeling and Simulation for Microtechnologies, Electronics, Microsensors, and Microactuators. She has published more than 40 articles in international journals, conferences, and book chapters, and 1 patent. She currently supervises 2 PhD thesis, 10 Master theses (7 completed), and 1 research fellow. She has also participated in 6 funded projects, in which she was Principal Investigator in 2 of these. Her research interests include diagnosis and lab-on-a-chip devices, optical and acoustic sensors and actuators, and numerical studies of acoustic streaming and microfluidic devices. vii micromachines Editorial / Editorial for the Special Issue on Micro Nano Devices for Blood Analysis SusanaO.Catarino1,*,GraçaMinas1,*andRuiLima2,3,* 1 CenterforMicroElectromechanicalSystems(CMEMS-UMinho),UniversityofMinho,CampusdeAzurém, 4800-058Guimarães,Portugal 2 CEFT,FaculdadedeEngenhariadaUniversidadedoPorto(FEUP),RuaRobertoFrias, 4200-465Porto,Portugal 3 MEtRICs,MechanicalEngineeringDepartment,UniversityofMinho,CampusdeAzurém, 4800-058Guimarães,Portugal * Correspondence:[email protected](S.O.C.);[email protected](G.M.);[email protected](R.L.)
