Figure 7.19 (a) Response of the sensor to addition of 1 mL of sample containing 10,
50, and 500 cysts mL −1 G. lamblia samples to the flow loop set in recirculation mode
at 2.4 mL min −1 . (b) Average frequency responses ( n = 4) to various concentrations at
2.4 mL min −1 . Negative control experiments showed responses of 20 ± 5 Hz ( n = 4). Error
bars represent one standard deviation ( n = 4). Source: Figure 2 from Ref. 90 . Reprinted

7.7. BIOSENSORS FOR THE DETECTION
OF WATERBORNE PARASITES
In terms of waterborne parasites, the biosensor community has mainly
studied Schistosoma , utilizing the presence of antibody within host serum
as the detection marker. Various different techniques have been proposed
including an amperometric immunosensor with an LOD of 0.36 µg mL −1 , 93
