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 [...]

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 [...]

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 [...]

Performance Comparison of Immunosensors Modified with Polymers, Nanoparticles and Antibody

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

Our research group is in the quest of developing a biosensor platform that is fast in response time, versatile that can be used to detect a variety of chemicals species and metabolites, and ultra-sensitive that [...]

Ultra-High Performance Immunosensor Prepared by Glassy Carbon Electrode Modified with Nano Gold Particles and Antibody

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

In previous reports, we have successfully fabricated biosensors that could measure chemical species that are important in environmental monitoring, as well as metabolites that are indicators of the proper functioning of our body. In our [...]

Surfactant Effect on Intercellular Transport of DNA, Proteins, and Electrolytes

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

Surfactants play a key role on bodily functions at molecular level, such as cell signaling and signal transmission. Their importance in cell survival is well recognized, but the surfactant effect on intermolecular/interfacial mass transport is [...]

Comparison of Anchoring Materials for High Performance Sensors Modified with Nanoparticles and Enzymes

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

We have previously developed some of the most sensitive biosensors/electrodes modified by Au nanoparticles and enzymes that are capable of detecting concentration levels below ppb. These sensors were fabricated with composite layers of nanomaterials and [...]
