Green‐tea‐synthesized silver nanoparticles as a sensing platform for determination of tetracycline in honey samples

BACKGROUND Silver nanoparticles (AgNPs) can be easily obtained in aqueous solution by chemical reduction using appropriate reducing agents and stabilizers. The development of environmentally friendly methods non-toxic solvents reagents has become an alternative for the synthesis these particles their future application as sensor probes agricultural products. In this work, a straightforward method based on green tea extracts capping agent is proposed AgNPs, followed evaluation sensing platform determination tetracycline honey samples. RESULTS Highly stable were combining ultrasound irradiation 2 min. as-synthesized spherical shape with average size 8.5 nm, evaluated following changes localized surface plasmon resonance band at 450 nm induced presence antibiotic pH 5.8. was successfully applied concentration range between 200 800 μg L-1 R2  > 0.996 limit detection 52.7 μg L-1 . Multiple samples analyzed, recovery values ranged 82.8% 116%, relative standard deviation lower than 6.69%. CONCLUSION results demonstrate that AgNPs synthesized just represent promising sustainable tool cost-effective antibiotics honey. © 2021 Society Chemical Industry.
