Abstract:

 


Pesticides have been utilized in agriculture for decades. However, their widespread use has increased

concerns due to their known toxicities on long term human health risks in scientific and industrial communities.

Thus, the detection of pesticides will have a great prescription due to both improve their toxicity effects over

humans and their management. In this study, poly[ethyleneglycol dimethacrylate-N-methacryloyl-(L)-tryptophan

methyl ester poly(EGDMA-MATrp) nanoparticles for sensitive, selective, fast and realtime detection chlorpyrifos

were firstly prepared and characterized by zeta sizer. Then, a chlorpyrifos-printed SPR nanosensor was prepared and

characterized by atomic force microscopy (AFM) and contact angle measurements. The thickness measurements

and AFM observations indicated that the nanoparticle thin films were almost monolayer. Chlorpyrifos sensing

ability of imprinted and nonimprinted nanosensors were investigated from chlorpyrifos solutions within the range

of 0.015-2.9 nM. Imprinted nanoparticles showed more sensitivity to chlorpyrifos than non-imprinted ones.

Langmuir adsorption model was determined as the most suitable model for this affinity system. In order to show

the selectivity of the chlorpyrifos imprinted nanoparticles, competitive adsorption of chlorpyrifos, diazinon and

parathion at 2.9 nM concentration was investigated. As a result of, SPR nanosensors have a potential to be used as

an alternative method for pesticides analysis due to fast response, easy-to-use properties, precision, selective and

real-time measurement capability.
