The site-directed modification of nanobodies through a genetic engineering technology for the fluorescent test strip detection of fenpropathrin

Key Points

• This research focuses on improving detection methods for fenpropathrin in food safety using engineered nanobodies.
• Developed a fluorescent test strip using nanobodies altered through genetic engineering.
• Utilized a lateral flow immunochromatography assay (LFIA) for rapid detection in a food safety context.
• Genetically engineered nanobodies showed enhanced specificity and sensitivity in detecting fenpropathrin.
• The LFIA method provides a rapid and effective solution for on-site food safety testing.
