چکیده

This study investigates the impact of key parameters, including aptamer concentration, aptamer incubation time, tetracycline (Tet) incubation time, pH, and temperature, on the peak current of an aptasensor designed for Tet detection. The aptasensor was developed by immobilizing a Tet aptamer onto gold nanoparticles (AuNPs) electrodeposited on an electrospun carbon nanofibers (CNFs). The integration of CNFs and AuNPs enhances the sensor's performance by increasing the surface area and improving conductivity. The results show that aptamer concentration, aptamer incubation time, incubation time of Tet, pH, and temperature affect the peak current of the aptasensor, demonstrating the importance as effective parameters in the preparation of biosensors.
