Comprehensive Analysis of High Performing Electrochemical Biosensors and Their Applications: II, System Update

Leung S.W., Lai J.C.K., 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 [...]

MCM-41 and Functionalized MCM-41 as Adsorbents to Remove Heavy Metals and Hardness from Contaminated Water and Groundwater

Leung S.W., Basnet N., Dejesus K., Lai J.C.K., Idaho State University, US

Mining operating and abandoned mines often have resulted in waste rock dumps and open pits that contain materials high in heavy metals and toxic elements. These contaminants are known to be present in groundwater, surface [...]

Cyanide Detection by Highly Modified Sol-Gel Biocomposite Sensor

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

Cyanide is an important industrial chemical but is also very toxic. Cyanide binds strongly with hemoglobin than that of oxygen which causes histoxic hypoxia, if cyanide is ingested into the bloodstream. This pairing reaction can [...]

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 [...]

Cytotoxic Effects of Four Metallic Oxide Nanoparticles on Dorsal Root Ganglion (DRG) Neurons

Lu S., Bhushan A., Leung S.W., Daniels C.K., Lai J.C.K., Idaho State University, US

Metallic oxide nanoparticles have diverse industrial applications because of their exploitable physico-chemical and other properties. Consequently, the occupational environmental exposure of humans to these nanparticles is increasing; however, the health impact of their exposure has [...]
