An optical fiber biosensor for chlorpyrifos using a single sol-gel film containing acetylcholinesterase and bromothymol blue
An optical fiber biosensor consisting of acetylcholinesterase (AChE) and bromothymol blue (BTB) doped sol–gel film was employed to detect organophosphate pesticide chlorpyrifos. The main advantage of this optical biosensor is the use of a single sol–gel film with immobilized AChE Read More …
Enzyme Inhibition Based Biosensors for Environmental Monitoring
A review of methods based on enzyme inhibition in environmental monitoring is presented, which is mainly focussed on the detection of pollutants, such as pesticides, heavy metal ions and other toxic compounds. The sensing principles, design of the biosensor and Read More …
Recent Advances in Optical DNA Biosensors Technology
Recent advances in nucleic acids-based biosensors have led to the development of DNA biosensors for DNA hybridisation detection and for nucleic acid-ligand binding studies. This review presents a concise description and an evaluation of the optical devices that have been Read More …
Simple optical fibre biosensor based on immobilised enzyme for monitoring of trace heavy metal ions
A simple optical fibre biosensor based on immobilised enzyme for monitoring of trace heavy metal ions has been developed. The biosensor recognition system was designed based on the inhibition of urease activity, where the urease is immobilised on ultrabind membrane. Read More …
Optical fibre biosensors based on immobilised enzymes
This review gives a general overview of optical fibre biosensors, their sensing principles and associated instrumental set-up. The techniques for the immobilization of enzymes is also covered. Enzyme-based optical biosensors are classified according to the type of optical transducer (including Read More …
