When selecting a sampling program, it is important that the analyst has a detailed description of the information required from the analysis, an estimate of the accuracy to be achieved, and an estimate of the amount of time and money that can be spent on sampling. The stationary phase consists of inert particles coated with a layer of liquid and is normally confined to a long stainless steel or glass tube called the column, which is maintained at appropriate temperature. These disadvantages have limited the frequent use of RIA in the day to day analysis of aflatoxins. These disadvantages have limited the frequent use of RIA in the day to day analysis of aflatoxins.

This review classifies voltammetric sensors according to whether the bacteria are directly or indirectly detected. ; Aylott, J.W. Whereas the B-group aflatoxins exhibit blue fluorescence, the G-group exhibits yellow-green fluorescence under ultraviolet (UV) light, thus making the use of fluorescence important in identifying and differentiating between the B and G groups. New trends in bacteria sensors involve DNA analysis, which makes it possible to improve the sensitivity and specificity of measurements. 141, no. The target bacteria can be detected and quantified with bacteriophage-based biosensors because bacteriophages specifically bind to the bacteria, since they are a type of virion that infect bacteria [, However, indirect detection of bacteria using biosensors has been preferred because of its better sensitivity and specificity compared to direct testing.

Such materials would allow for polarized light to exit the original waveguide, undergo total internal reflection (TIR) at the coating-liquid interface, and eventually reenter the waveguide. The limit of detection is also slightly higher than the limit of 4g/Kg set for European settings and thus may not be good for analyzing samples from products to be exported to Europe.
