Photonic Crystal Fiber Based Refractive Index Sensor

Nazeri K., Ahsani V., Ahmed F., Lee P-C, Jun M.B.G., Purdue University, US

Photonic Crystal Fiber (PCF) is an optical fiber which owes its waveguide properties to an arbitrary arrangement of closely-spaced and tiny air holes that go through the whole length of fiber. Much attention has been [...]

Self-Sustained Infrared Temperature Sensor Arrays

Mittmann Reis R., Rochester Institute of Technology, US

The constantly growing needs for solid-state temperature sensors motivates micromachined thermopile sensors [1-11]. We examine the Seebeck effect and discuss the the key physical parameters and characteristics. The micromachined microstructures are designed and fabricated. We [...]

Self-Assembled Polystyrene Nanospheres for Plasmonic Enhancement in Biosensor Applications

Smith K., Norville C., Windham M., Dawson J.M., West Virginia University, US

The field of portable, point-of care biosensing has expanded in recent years to encompass a wide range of application areas, with detection of targets accomplished by a variety of techniques. Application-specific needs of further reduced [...]

Real-time bacterial capture and sorting using dielectrophoresis and electroosmosis

Simon S.X., Markewich H., Mallick E., Weber M., Fluid-Screen, Inc., US

Fluid-Screen, Inc. presents a bacterial capture and sorting method based on dielectrophoresis (DEP) and electroosmosis (EO). These electronic phenomena have been known to influence particle motion and capture since the 1960’s, however, technology based on [...]

Laser-Induced Motion of a Nanofluid in a Micro-channel

Tran P.X., Wang P., National Energy Technology Lab, US

Interaction of a millimeter sized droplet on the powder substrates and study of capillarity in porous media flow

Avhad A.G., Tan H., Washington State University, US

Droplet impact on powder materials is a ubiquitous phenomenon in nature and engineering technologies including powder-binder based 3D printing, wet granulation, spray drying, powder coating, agricultural sprays, water erosion of soil, and raindrops landing on [...]

Numerical Analysis of Acoustophoretic Discrete Particle Focusing in Microchannels

Karampelas I.H., Gómez-Pastora J., Cowan M.J., Bringas E., Ortiz I., Furlani E.P., Flow Science Inc., US

Acoustophoretic particle focusing is a modern and very attractive method of removing a variety of objects from solutions in a microfluidic channel [1]. The process is inherently general and can be readily extended for multiple [...]

3-D electrode configuration for electrochemical impedance spectroscopy of bulk solution

Wang A., Koh D., Schneider P., Oh K.W., University at Buffalo, US

Abstract In this paper, a 3-D electrode configuration for electrochemical impedance spectroscopy (EIS) of a bulk solution was studied. Top- and bottom- electrode configuration, where two electrodes sandwich the sensing channel, was fabricated using the [...]

Self-navigating drug delivery nanovehicles driven by polyvalent multifunctional phages and their promiscuous proteins

Petrenko V.A., Gillespie J.W., Auburn University, US

Development of precision medicines acting specifically at the site of disease has been a long sought goal for the last century, starting from pioneering works of Paul Ehrlich, who suggested the concept of site-directed chemotherapeutics [...]

Cancer Nanomedicines: Challenges and Opportunities

Tamarkin L., CytImmune Sciences, Inc, US

The treatment of cancer remains an ever-growing problem. Treating solid tumors as a medical disease first, using the natural biology of tumors to reduce or eliminate tumors in situ, offers patients and the entire healthcare [...]
