DETECHIP®: Developing a Molecular Sensing Device

Okuom M.O., Holmes A.E., Doane College, US

DETECHIP® is a detection system made of various sensors that has been shown to detect and discriminate between small molecules of interest, including various illicit drugs for and over-the-counter medications, explosives, pesticides and food spoilage [...]

Resistance and Potentiostatic Based Measurements of an Antibody Functionalized Conductive Polymer Coated Textile as a Biosensor

Bandremer A., Hebert A., Torosian S.D., Battacharyya D., Gleason K., McGraw S.K., Senecal A., Marek P., Food and Drug Administration, US

Effective food safety monitoring is challenged by the necessity to identify human infection capable microorganisms at sufficient infective doses and consumption levels. Regulatory agencies have developed methods for assessing food safety based on currently available [...]

Nanostructured Biomimetic Memristor Sensors Used for Therapeutic Monitoring of the Brain Cancer

Chen E.T., Thornton J., Ngatchou C., Duh S-H, Kissinger P.T., Advanced Biomimetic Sensors, Inc., US

Current technology is not available to provide a portable, simple and accurate real-time monitoring and treatment of cancers simultaneously in an early stage at a clinical setting. Challenges for developing such a tool, include the [...]

Detection of Prostate-Specific Antigen (PSA) with an Ultra High Performance Electrode Modified with Sol-Gel Au Nanoparticles

Leung S.W., Mozneb S., Lai J.C.K., Assan D., Idaho State University, US

Prostate cancer is one of the leading cancer causing death in men, especially in western developed countries. Prostate-specific antigen (PSA) is one of the biomarker that can be used to diagnose prostate cancer, although using [...]

EXIRM: A Novel Technique for Label-Free Detection of MicroRNA

Wang Y., Xu S., University of Houston, US

MicroRNAs play important roles in cancer and other diseases. However, due to the transient nature of the MicroRNAs, it remains challenging to achieve high sensitivity and accuracy to quantify MicroRNAs. We are developing a new [...]

Ultrasensitive and rapid immuno-detection of bacteria and protein biomarkers using field-effect enzymatic detection

Yau S.-T., Cleveland State University, US

A novel immuno-detection system has been constructed by incorporating the newly invented field-effect enzymatic detection (FEED) technique the immunosensing technique to demonstrate a novel detection platform. The demonstration consists of the detections of three biomarkers [...]

Nanostructured Memristor Sensor Mimics Acetylcholinesterase (ACHE) Active Sites in the Gorge for fM Detection of Acetylcholine

Chen E.T., Thornton J., Ngatchouand C., Duh S-H, Advanced Biomimetic Sensors, Inc., US

Many diseases including cancer, diabetes, brain injury, epilepsy, Parkinson’s, autism and Alzheimer’s involve the up regulation of acetylcholinesterase (ACHE) inappropriately signaling of cholinergic synapse for an excess production of the neurotransmitter acetylcholine (ACH). Challenges for [...]

Superhydrophobic 3D Printed Surfaces by Dip-Coating

Milionis A., Loth E., Bayer I.S., University of Virginia, US

Here we demonstrate a technique to fabricate three-dimensional superhydrophobic patterns. First a three-dimensional pattern was designed by 3D printing using acrylonitrile butadiene styrene (ABS) as printing material. A linear printing algorithm is followed for the [...]

A Simple and Robust Fabrication of Microwell Array by Pdms on a Glass Substrate for Cell-To-Cell Adhesion

Lee H., Row S., Xu L., Andreadis S.T., Oh K.W., SUNY at Buffalo, US

We describe a simple micro-fabrication method by using polydimethylsiloxane (PDMS) patterns on a glass substrate that enables simultaneous control of cell-to-cell adhesion. While the microwells used previously facilitated the cell-to-cell formation by PDMS stamping method, [...]

Modeling of liquid pumping via microchannels

Berdenova B., Ainabayev A., Insepov Z., Hassanein A., Bralts V., Insepov Z., Purdue University, US

We present our finite element modeling and discuss the main principles of our water actuation technique for water transport in micron scale tubes. The effect of water flow actuation by application of surface acoustic waves [...]
