An impedimetric-based biosensor constructed using gold nanoparticles (AuNP) entrapped within titanium dioxide (TiO₂) particles for hydrogen peroxide (H₂O₂) detection is the main feature of this research. The matrix of the biosensor employed the surface of TiO₂, which was previously modified with an amine terminal group using 3-Aminopropyltriethoxysilane (APTS) at a low temperature to create a r...

Drunk driving is, in Canada, the leading cause of death on the roads. To reduce the number of drinking and driving incidences, new technologies were developed to accurately measure blood alcohol concentration (BAC) and overcome the limitations of current alcohol measuring technologies. In this research, a non-contacting, non-invasive in-vehicle alcohol biosensor is developed using laser-based W...

In this study, a novel indium tin oxide (ITO)-polyaniline (Pani) biosensor was designed, fabricated, and characterized. Initial testing was conducted for the detection of bovine viral diarrhea virus (BVDV). The biosensor design was based upon the specific nature of antibodies to capture the target virus, and the conductive properties of self-doped Pani to translate the antibody-antigen binding ...

In this paper a novel elctrochemical HbA1c biosensor based on flow injection and screen-printed electrode was developed. The reticulated vitreous carbon (RVC) electrode was modified with 3aminophenylboronic acid, chitosan (CS), and tetraenthoxyl silica (TEOS), which entrapped carbon nanotubes to form a sol-gel film at the surface of the screen-printed electrode. The electrochemical behavior of ...

A monolithically integrated micro-fluidic biosensor system-on-chip (μBio-SSoC) is first realized in standard CMOS processes. This μBio-SSoC is composed of a CMOS-based microfluidic pump, a polysilicon nanowire (SiNW) biosensor, and driving circuits. With 1.5V driving voltage, the microfluidic pump drives sample-liquids to biosensing area with 34 μm/s flowing velocity. After pumping, the detecti...

This work is about gas biosensing with a cytochrome c biosensor. Emphasis is put on the analysis of the sensing process and a mathematical model to make predictions about the biosensor response. Reliable predictions about biosensor responses can provide valuable information and facilitate biosensor development, particularly at an early development stage. The sensing process comprises several in...

A quartz crystal microbalance (QCM) biosensor based on polydopamine (PDA) surface was developed for real-time analysis of the binding kinetics of protein-protein interactions. The biosensor was fabricated by simply immersing the gold sensor chip into an aqueous dopamine solution at pH 8.5 leading to a spontaneous deposition of PDA film onto the sensor chip surface, which was followed by incubat...

In this work, fabrication of gold coated glass substrate, growth of ZnO nanorods and potentiometric response of lactic acid are explained. The biosensor was developed by immobilizing the lactate oxidase on the ZnO nanorods in combination with glutaraldehyde as a cross linker for lactate oxidase enzyme. The potentiometric technique was applied for the measuring the output (EMF) response of l-lac...
