The device initially focuses and concentrates the bacteria into the centerline of the microchannel, and directs them toward the sensing region. The bulk media will be directed to the waste outlets through the outer channel. The bacteria will then be trapped on top of the sensing region using trapping electrodes which confine and facilitate the contact and binding of salmonella antigens with salmonella antibody immobilized on the detection electrodes. Various low concentration E.coli and Salmonella samples were tested with and without the trapping electrodes to determine the sensitivity of the biosensor. The lowest measured concentration of Salmonella cells was found to be 13 cell/ml with a detection time of 30 minutes. Biography Mahmoud Almasri received BSc and MSc degrees in physics from Bogazici University, Istanbul, Turkey, in 1995 and 1997, respectively, and a PhD in electrical engineering from Southern Methodist University (SMU), Dallas, TX, in 2001. He is currently an associate professor with the Department of Electrical Engineering and Computer Science, University of Missouri. From 2001 to 2002 he was a research scientist with General Monitors, Lake Forest CA. From 2002 to 2003 he was with College of Nanoscale Science and Engineering Albany, NY, as a post doctoral research associate, and from 2004 to 2005 he was with Georgia Institute of Technology as a post doctoral fellow, and a research scientist. His current research include impedance biosensors, MEMS capacitors for power harvesting, Si-Ge-O infrared material, metasurface based uncooled IR detectors, and MEMS Coulter counter for studying time sensitive cell. His research is funded by agencies such as NSF, USDA, ARO, Leonard Wood Institute, and Coulter Foundation.

While traditional methods, Esuch as visual identification of malignant changes, cell growth analysis, specific-ligand receptor labeling, or genetic testing often require lengthy analysis, a combination of ultrasensitive magnetic field sensors with functionalized magnetic nanoparticles offers a promising approach for a highly sensitive, simple, and quick detection of cancer cells and biomolecules. In this talk, I will review recent progress in the development of magnetic impedance biosensors using nanoparticles. I will present a new approach that integrates the magneto-resistance (MR), magneto-reactance (MX), and magneto-impedance (MI) effects to develop a functional magnetic biosensor with tunable and enhanced sensitivity. The MX-based probe shows the most sensitive detection of superparamagnetic nanoparticles (~10 nm diameter) at low concentrations. A novel biosensor based on the MX effect of a soft ferromagnetic ribbon with a microhole-patterned surface has been developed, demonstrating its high capacity for the detection and quantification of anticancer drugs and proteins tagged to Fe3O4 nanoparticles, as well as Lewis lung carcinoma (LLC) cancer cells that have taken up Fe3O4 or MnO nanoparticles. Finite element simulation fully supports the experimental observations. Finally, novel classes of magnetic nanostructures for advanced biosensing and new exploration in medical diagnostics will be discussed. Biography Manh-Huong Phan has obtained a global education with BS, MS and PhD degrees in Physics from Vietnam National University (2000), Chungbuk National (2003), and Bristol University – United Kingdom (2006), respectively. He is an Associate Professor of Physics at the University of South Florida. He has published more than 230 peer-reviewed journal papers (h-index: 37 from Google Scholar) and one text book. He is an Associate Editor for the Journal of Electronic Materials and the Managing Editor for the Journal of Science: Advanced Materials and Devices.

However for these devices to be useful their sensitivity and lifetime must be sufficient for them to be operated by portable low-cost electronics. This talk will describe our research on the design of a new class of redox polymers based on attaching ferrocene (Fc) redox centers to linear polyethyleneimine (LPEI). We will provide an overview of how the polymer and redox center structure affects their stability, redox potential, and ability to electrically communicate with enzyme redox centers? We will discuss, how these novel redox polymers can electrically communicate with the redox centers of a variety of enzymes (e.g. glucose oxidase, horseradish peroxidase, fructose dehydrogenase) and generate bioelectrocatalytic current densities >1 mA/ cm2? Finally, we will discuss how these redox polymers can be combined with the unique properties of Single-Walled Carbon Nanotubes (SWNTs) for both biosensing and enzymatic biofuel cell applications?.

The former is studied at the chemical, physical, biological, physiological, brain, and sociological layers. However, the latter is studied at data, information, knowledge and intelligence layers underpinned by mathematics as the general abstract science. Bioengineering is a trans-biological-and-engineering filed that solves organic, life, body and brain problems as well as medical, agricultural and socioeconomical applications at the molecular, gene and neural levels. Cognitive engineering is an adjacent layer beyond bioengineering that study cognitive and brain-inspired systems based on cognitive and intelligence sciences. Both biological and cognitive engineering leads to brain-inspired systems and AI applications which are bioengineered and cognitively implemented mimicking the brain and the natural intelligence. Latest basic studies reveal that novel solutions to fundamental
