Applications of electronic nose based on MOX and QMB sensors
(International Frequency Sensor Association, 2012-05)
The electronic nose emerged in the mid 80´s due that the food industry needed quickerinstruments to be applied in food control for the characterization of smell, in order to complement thework done by human panels. But ...
Development of an electrochemical sensor for determination of dissolved oxygen by nickel-salen polymeric film modified electrode
(Elsevier B.V. Sa, 2012-12-01)
An amperometric oxygen sensor based on a polymeric nickel-salen (salen = N,N'-ethylene bis(salicylideneiminato)) film coated platinum electrode was developed. The sensor was constructed by electropolymerization of nickel-salen ...
A new biomimetic sensor based on molecularly imprinted polymers for highly sensitive and selective determination of hexazinone herbicide
(2014)
A new selective sensor based on molecularly imprinted polymers (MIPs) was developed for the determination of hexazinone (HXZ) in environmental samples. MIPs were synthesized using a non-covalent approach, and selection of ...
