Description Not Available
An electrochemical aptasensor for detection of
trace amounts of aflatoxin M1 was developed. This
required immobilization of aptamer on screen printed gold
electrode comprising of working electrode, counter elec trode and reference electrode and was achieved by
sequentially layering dithiodipropionic acid, streptavidin
and biotinylated-tetraethylene glycol-aptamer. Immobi lization of aptamer was monitored by cyclic voltammetry.
Peak current in square wave voltammogram was inversely
related to logarithmic concentration of aflatoxin M1.
Dynamic range of sensor was 1–105 ppt aflatoxin M1.
Sensor can be regenerated by treating electrode with 10%
sodium dodecyl sulfate or 40 mM tris-HCl (pH 8.0) con taining 10 mM ethylenediaminetetraacetic acid and 0.02% tween-20
