Biosensors Research Group
UNIVERSITI MALAYSIA SABAH
Research Lines
Our research groups are involved in the development of nano-biochips, nano-biosensor and nano-biomaterials based on the exploitation and utilization of bio-contents. By conducting joined research in the fields of biotechnology, electrochemistry, nanotechnology and new drug discovery technology.
DNA Biosensor Based the Detection of Microorganisms
The identification of microorganisms have usually been based on conventional culturing techniques, which are time consuming, requiring 4-5 days for preliminary results and an additional five (5) days for confirmation.
Determination of Formaldehyde in Fish Samples Based on Electrochemical Biosensor
The newly formaldehyde biosensor is developed based on enzyme (nicotinamide adenine dinucleotide, NAD+, formaldehyde dehydrogenase, FDH) and nanomaterial (carbon nanotubes, nanoparticles, chitosan) for the detection of formaldehyde in fish samples.
Nanoparticles-Coated Eggshell Membrane with Immobilized Enzymes for Fabrication of Enzymes Biosensor
With high consumption of eggs, the waste by-products are either dumped at the dump site or burned for easy disposal. The gross majority of egg consumption takes place in the intensely populated region of Asia where this protein serves as a major food.
Nanosensor Based Determination of Total Cholesterol in Food Samples
​
Cholesterol is a structural component of biological membranes. It is present in egg yolk, dairy products, goat meat, beef meat, chicken meat etc. Cholesterol is an essential biomarker in the clinical diagnosis of hypertension and arteriosclerosis.
Electrochemical Biosensor-Based Rapid Detection of Melamine in Raw Milk and Milk Products
Melamine (C3H6N6) (Mel; 1,3,5-triazine-2,4,6-triamine) is a small polar nitrogen rich compound (67% by mass) which is widely used for the production of plastics, amino resins and flame retardants.
