Combined effects of pump and capillary pressures for the filling of microchannel networks: the difficulty of synchronization

Berthier J., Diakite M.L., CEA-Leti (University Grenoble Alpes), FR

In this work, we first propose a model for the filling of a capillary tube driven by a pressure pump. It is shown that the filling time depends not only on the pump pressure but [...]

Research on human-computer interaction technology based on electrical detection technology

Han H-P., Tang K., Lang X-Q., Chen X., Beijing Institute Technology, CN

Human-computer interaction (HCI) technology has emerged as a crucial dimension of computer science and information industry. HCI with keyboard and mouse has started to lose ground, as people tend to harness the power of body [...]

Nanobiomimetic Memristor/memcapacitors’ Function as a Voltage Sensor for Direct and Reagent-free Detection of sub pg Lipopolysaccharide (LPS) in Milks for Children

Duh S-H, Thornton J., Kissinger P.T., Chen E.T., advanced biomimetic sensnors, inc, US

Lipopolysaccharide (LPS) is a common endotoxin from E. Coli bacteria, and is the major source causing infection diseases over 20 million people worldwide. Lack of sensitivity and high imprecision from common commercial test methods are [...]

Nanobiomimetic Memristor/Memcapacitor Devices Used for Direct and Reagent-less Detection of Sub pM Acetyl Coenzyme A in Milks

Duh S-H, Thornton J., Kissinger P.T., Chen E.T., advanced biomimetic sensnors, inc, US

Acetyl co-enzyme A (AcCoA) is a leading substrate in a large variety of enzyme-catalyzed reactions, such as for choline acetyltransferase and acetylcholinesterase. They are critical to energy production, metabolism, memory, cell proliferation and early childhood [...]

High efficiency capture of multiple bacterial species by microfluidic dielectrophoresis filter

Simon S., Weber M., Fluid-Screen, Inc., US

Fluid-Screen, Inc. presents a bacterial concentration and filtration method based on dielectrophoresis (DEP). DEP has been known to induce particle motion since the 1960’s. However, yields and reproducibility have consistently been low in practice, reducing [...]

The OsteoAccess System – Low-Force, Controlled Angled Bone Access for Bone Biopsy and Bone Marrow Aspiration

Mulvihill M.L., Ashuckian E.D., Greaser J.K., Hartung K.M. Erdley H., Bagwell R.B., Actuated Medical Inc, US

Many medical procedures and diagnostics require penetrating hard cortical bone. For example, biopsies and aspirates taken from within bone are used to diagnose a wide range of cancer and blood diseases. Sampling locations can include [...]

The Detection of PETN Using a Bulk Single Wall Carbon Nanotube/Peptide System

Kubas G., Rees W., Caguiat J., Asch D., Fagan D., Cortes P., Youngstown State University, US

The present research work investigates the novel detection of pentaerythritol tetranitrate (PETN), a high powered explosive, using peptide surface functionalized single wall carbon nanotubes. Here, through the use of a phage display technique and enzyme-linked [...]

Analytical sensing platforms with inkjet printed electrodes

Lesch A., Jović M., Gumy F., Girault H.H., EPFL Valais Wallis, CH

Medical diagnostics for the determination and monitoring of the health condition of patients, sportsmen but also normal persons represents an important market with increasing opportunities for sensor platform development, production and applications. For instance, amperometric [...]

Effect of silver coated carbon nanotubes on metabolically essential gene expression and outer membrane protein profile of Escherichia coli

Chaudhari A.A., Singh S.R., Pillai S., Alabama State University, US

Antibiotic resistance acquired by food borne pathogens such as E. coli has become a global concern. Recently, nanoparticles have been shown to be effective alternatives to antibiotics. Specifically, silver coated carbon nanotubes (AgCNTs) have been [...]
