Aptasensors for Pesticide Detection

Pesticides are one of the prominent issues in food safety and environmental pollution, and a rapid pesticide residue detection method is urgently needed to keep humans from being affected. Aptamers are single stranded DNA- and RNA- based oligonucleotides that can bind to their targets with high affinity and specificity, and have tremendous applications as therapeutic and diagnostic agent. The properties of conformational changes upon target-analyte binding make them most appropriate and suitable candidate to design label free and portable bio-devices for analytical applications.
