Utility Biosensors for applications in Agriculture–A Review #29
=> We should not orient ourselves in biosensors for the food industry because so many papers have already been published.
Additional research on different topics confirm that idea.
For agriculture, all the main pathogens can already be detected with a variety of biosensors. Some more « niche » problems in agriculture (organic agriculture?) could be considered.
Applications of biosensors:
Food/fruit quality control
Biochemical composition of fruits
Fruit maturity, ripening and quality relationships
Major organic acids in fruits
Organic acid as an indicator of fruit maturity
Effects of shelf life on the changes in organic acid of fruits
The article gives successful examples of:
organic acid biosensors
A disposable prototype electrochemical screen-printed biosensor was constructed using pyruvate dehydrogenase immobilized on mediated electrodes and a combined Ag/AgCl reference/counter electrode, both screen-printed onto a PVC substrate to determine pungency in onions.
glucose biosensors
Most of the glucose biosensors developed are based on immobilized glucose oxidase on different surfaces like crystalline gold, ferrocene and GOx, an electrochemically synthesized, nonconducting poly(o-aminophenol) film… The detection can be done through an amperometric nitrocellulose electrode strip having an oxydation layer.
Since the discovery of carbon nanotubes, CNs have been extensively used in the fabrication of electrochemical sensors and biosensors.
=> there are too many possible materials and examples, we should not go in that direction.
ascorbic acid sensor
Ascorbic acid has been measured both by direct electrochemical oxidation and by enzymatic methods using ascorbate oxidase
