Description

FSTest Paper-based test strips was developed for the simple and rapid screening of organophosphate (OP) and carbamate (CM) pesticides based on the inhibition effects against acetylcholinesterase (AChE) activity.

In detail, the OP and CM pesticides in the sample have an inhibitory effect on AChE, which can catalyze the hydrolysis of indophenol acetate to produce acetic acid and indophenol.  As a result, the indophenol is shown in blue, causing the change of color on the detect card.  Thus, the absence or decrease of blue color is related to the amount of OP and CM residues in samples.  The color signal in test zone makes the interpretation visual and easy, which ensures the limit of detection (LOD) of Carbofuran, DDVP, Methomyl, Dipterex and Profenofos reach to 0.02, 0.2, 0.2, 0.1, and 0.5 ppm, respectively.

Each FSTest Paper-based test strips consists of a foldable red cover and white detection sheets, which are pre-prepared with indoxyl acetate and AChE respectively.  The card is designed at low-cost, with minimal reagents required, high detection sensitivity and easy to handle.  Therefore, it would be friendly for operators without professional backgrounds.
