Comprehensive Analysis of High Performing Electrochemical Biosensors and Their Applications

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

We have mounted 5 different biocatalysts on a sensor platform to examine the performance of this electrochemical sensing system for the detection of different biomolecules/metabolites and environmental important molecules, with such we also compared how [...]

Improving the sensitivity of Pedot:Pss modified gold electrode using gold and silver nanoparticles for Ganoderma boninense DNA detection

Dutse S.W., Yusof N.A., Ahmad H., Hussaini Adamu Federal Polytechnic, NG

The sensitivity of a designed electrochemical DNA biosensor was improved using gold and or silver nanoparticles. A gold electrode modified with a conductive nanocomposite of poly(3,4-ethylenedioxythiophen)–poly(styrenesulfonate) (Pedot-Pss) and gold or silver nanoparticles enhanced the conductivity [...]

A New Biocomposite Electrode Sensor for the Detection of Oxidative Reactions

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

Hemoglobin has a very strong affinity with oxygen and thus is a good catalyst to carry oxygen for many oxidation reactions. Many researchers have explored this property of hemoglobin to develop sensors for the detection [...]

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 [...]

Nano-Power Implantable Autonomous Closed-Loop CMOS Nerve-Growth-Factor Delivery Microsystem for Neurological Disorders Personalized Therapy

Poustinchi M., Musallam S., McGill University, Neural Prosthetics Laboratory, CA

480 million patients around the globe suffer from neurological disorders which are the fastest-growing disease worldwide. Many neurological and psychiatric conditions are the result of abnormal neurotransmitter concentrations in the brain. Our ultimate goal is [...]

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 [...]

Cell Detection and Discrimination by a Microfluidic-Integrated Broadband Microchamber

Denzi A., Apollonio F., Liberti M., Caterina M., Ning Y., Multari C., Palego C., Cheng X., Hwang J.C.M., Lehigh University, US

In the last years, the development of broadband microwave sensors for cell detection has become a great challenge. In this work, a broadband microchamber integrated with microfluidics is used for cell detection in the GHz [...]
