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 [...]

Facile synthesis of graphene and its application in the preparation of L-Asparginase based sensor obtained from Bacillus cereus strain for the detection of leukemia

Talat M., Kumar Pandey R., Medicherla J.V., Nath Srivastava O., Banaras Hindu University, IN

The current study presents the development of a novel, diagnostic and cost-effective L-Asparaginase based biosensor conjugated to graphene for monitoring asparagines in leukemic patients. L-Asparaginase (E.C. 3.5.1.1) acts as an anti-leukemic agent by inhibiting the [...]

Nephrotoxicity of Dextran Functionalized Graphene Nanoparticles and Their Potential as Magnetic Imaging Contrast Agents for Renal Abnormalities

Lee S., Kanakia S., Toussaint J., Kukarni P., Chowdhury S.M., Khan S., Shroyer K., Moore W., Sitharaman B., Stony Brook University, US

Contrast-enhanced magnetic resonance angiography (MRA) employs the use of blood pool contrast agents (CA) such as gadolinium (Gd3+) complexes that allow for delayed phase arterial and venous imaging and improve the sensitivity in detecting small [...]

Substrate addition and matrix optimization increased sensitivity and selectivity of the PLGA sensor, resulting in a stronger detection signal toward bacterial contaminations

Ibrisimovic M., Ibrisimovic N., Ibrisimovic M., Ibrisimovic N., Kesic A., Mehmedinovic M., Ibrisimovic M., Ibrisimovic N., Faculty of Science, University of Tuzla, BA

The aim of this work was to contribute to the development of a simple and cheap biomimetic sensor, providing a higher sensitivity and selectivity toward microbiological contaminations. An optimization of the matrix of the optical [...]
