Detection of Dna Hybridization on a Configurable Digital Microfluidic
DETECTION OF DNA HYBRIDIZATION ON A CONFIGURABLE DIGITAL MICROFLUIDIC BIO- CHIP USING SPR IMAGING Lidija Malic1, Teodor Veres2 and Maryam Tabrizian1 1Biomedical Engineering Department, McGill University, CANADA and 2Industrial Materials Institute, National Research Council, CANADA ABSTRACT This paper presents a configurable digital microfluidic-based surface plasmon resonance (SPR) biochip platform comprising an electrowetting-on-dielectric (EWOD) microfluidic device coupled to SPR imaging (SPRi). We demonstrate its application for dynamic on-chip simultaneous immobilization of different DNA probes in combination with multichannel label-free real-time detection of subse- quent hybridization reactions. The integrated EWOD-SPRi system would enable the development of high-throughput, rapid and ultrasensitive biomolecular detection strategies beyond DNA microarray applications. KEYWORDS: Digital microfluidics, EWOD, SPR imaging, DNA hybridization INTRODUCTION EWOD microfluidics has attracted considerable attention in the past decade and the most recent efforts are directed towards its application in biomedical research [1- 3]. While these studies demonstrate the versatility of EWOD devices, the reported applications involve homogeneous phase reactions [4] and detection methods that require labeled biomolecules [2] or sample extraction from the chip [1]. This in- creases both the time and complexity of the assay. To introduce new applications relying on label-free, real-time surface sensitive detection techniques such as SPRi, it would be advantageous to use droplet-based EWOD actuation for surface specific biomolecule immobilization. However, the need of hydrophobic properties for EWOD actuation renders immobilization of biomolecules such as DNA on the sur- face of the chip impossible [3, 4]. In this paper, we demonstrate for the first time the use of an EWOD microfluidic chip to dynamically immobilize DNA probes in a two-dimensional array, followed by SPRi detection of bioaffinity interactions. -

Lab-On-Chip Microdevices for Capturing, Imaging and Counting White Blood Cells
LAB-ON-CHIP MICRODEVICES FOR CAPTURING, IMAGING AND COUNTING WHITE BLOOD CELLS by Anurag Tripathi A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy (Mechanical Engineering) in The University of Michigan 2012 Doctoral Committee: Associate Professor Nikolaos Chronis, Chair Associate Professor Katsuo Kurabayashi Assistant Professor Jianping Fu Assistant Professor Sunitha Nagrath To The Almighty And To My Family & Friends ii ACKNOWLEDGEMENTS It is my honor and absolute pleasure to acknowledge people who made this thesis possible. First and foremost, I would like to thank my advisor Dr. Nikos Chronis whose guidance and training enabled me to develop skills in microfabrication and microfluidics technology. More than the technical knowledge I gained from Dr. Chronis in the past five years, he taught me the virtues of hard work, sincerity and integrity. In the toughest of situations, his patience and understanding provided me with courage and confidence and enabled me to see through those hard times. He inculcated a strong aptitude for research in me and his ‘never give up’ principle left an indelible impression on my problem solving approach. I would be eternally grateful to Dr. Chronis for mentoring me and transforming me into a better researcher and a better human being. A big gratitude is in order for the other three members of my thesis dissertation committee, Dr. Katsuo Kurabayashi, Dr. Jianping Fu and Dr. Sunitha Nagrath. It was a privilege to have them on my committee. I thank them wholeheartedly for their valuable inputs during the Ph.D. preliminary examinations. I acknowledge the encouragement they provided to my research and would like to thank them for their support and motivation all this while. -
The Bio Revolution: Innovations Transforming and Our Societies, Economies, Lives
The Bio Revolution: Innovations transforming economies, societies, and our lives economies, societies, our and transforming Innovations Revolution: Bio The The Bio Revolution Innovations transforming economies, societies, and our lives May 2020 McKinsey Global Institute Since its founding in 1990, the McKinsey Global Institute (MGI) has sought to develop a deeper understanding of the evolving global economy. As the business and economics research arm of McKinsey & Company, MGI aims to help leaders in the commercial, public, and social sectors understand trends and forces shaping the global economy. MGI research combines the disciplines of economics and management, employing the analytical tools of economics with the insights of business leaders. Our “micro-to-macro” methodology examines microeconomic industry trends to better understand the broad macroeconomic forces affecting business strategy and public policy. MGI’s in-depth reports have covered more than 20 countries and 30 industries. Current research focuses on six themes: productivity and growth, natural resources, labor markets, the evolution of global financial markets, the economic impact of technology and innovation, and urbanization. Recent reports have assessed the digital economy, the impact of AI and automation on employment, physical climate risk, income inequal ity, the productivity puzzle, the economic benefits of tackling gender inequality, a new era of global competition, Chinese innovation, and digital and financial globalization. MGI is led by three McKinsey & Company senior partners: co-chairs James Manyika and Sven Smit, and director Jonathan Woetzel. Michael Chui, Susan Lund, Anu Madgavkar, Jan Mischke, Sree Ramaswamy, Jaana Remes, Jeongmin Seong, and Tilman Tacke are MGI partners, and Mekala Krishnan is an MGI senior fellow. -

Comparison of Specificity and Sensitivity of Biochip and Real-Time Polymerase Chain Reaction for Pork in Food
Journal of Food and Nutrition Research (ISSN 1336-8672) Vol. 58, 2019, No. 3, pp. 225–235 Comparison of specificity and sensitivity of biochip and real-time polymerase chain reaction for pork in food ZuZana DrDolová – Ľubomír belej – joZef Golian – lucia benešová – joZef Čurlej – Peter Zajác Summary Adulteration and food fraud are serious global problems. Analytical methods regarding animal species should repre- sent a comprehensive tool for identification and possible quantification of the components. The aim of the study was to confirm usability and sensitivity of the MEAT 5.0 LCD-Array Kit (version 5.0, Chipron, Berlin, Germany) for forensic analysis of food, which simultaneously detects 24 kinds of animals. We verified its reliability for identification of pork mixed with meat of other 15 animal species. Mixtures of animal species meat were tested in the raw state and after heat treatment. For comparison, real-time polymerase chain reaction innuDETECT Pork Assay (Analytic Jena, Berlin, Germany) with quantitative potential was used. A standard pork DNA curve was established and the detection limit was determined. MEAT 5.0 LCD-Array Kit was found to have a high degree of robustness, probe specificity and repeat- ability, with a detection limit down to 0.5 % (w/w) but did not allow quantification. We also used both test methods for analysis of commercial products. By these analyses, we identified the presence of pork DNA in 14 products for which this fact was not reported on the product label.

Monoclonals 5/10/06 11:51 Page 17 Therapeutics MONOCLONALS the billion dollar molecules of the future In 1975, two British scientists thought of creating a mouse antibody that could be replicated or ‘cloned’ to produce identical copies. Identical copies with identical modes of action had the potential to be a drug.They had launched what was to be one of biotechnology’s best ideas. If the pair could mimic the immune system’s ‘seek and destroy’ capability by pre-designing antibodies for all manner of disease targets, it should be possible to block or activate cellular activity to order. It was an elegant concept opening up a raft of therapeutic possibilities, particularly in the area of cancer. Here it might be possible to attach a chemotherapy drug to an antibody.The antibody’s specificity for a particular disease target would guide the chemo drug only to the cancerous cells and not the healthy ones.The concept, therefore, was excellent, but the use of mice monoclonals had drawbacks.The human body did not like antibodies from mice anymore than it liked the flu virus, so the antibodies themselves triggered an immune response and were destroyed.This ‘immunogenicity’ issue was to occupy researchers for another 20 or so years before it became possible to craft a monoclonal antibody (mAb) that would be acceptable to the human immune system. fter rather a long period in the desert, untreatable diseases.
