Trends in detection of toxins in foods
Microbial toxins in some aspects are easier to detect
than the cell that produced it. Although the actual toxin produced
is in the order of ng there are multiple copies thereby
enabling sensitive detection. The majority of sensors developed
have been based on immunoassay coupled with immunocapture
or flow through microfluidics with the
antibodies immobilized on the sensor surface (Ching
et al., 2012). The main innovation has been the adoption
of microfluidic and electrochemical or electrical detection
derived from the classic ELISA assays
