Synthesis of gold nanodendrites on hollow carbon spheres as an electrochemical sensorfor the determination of morphine in biological samples

In this study, first broken hollow carbon spheres (BHCS) was synthesized using the well-known Stobertemplating method. Then, Au nanodendrites (Au NDs) were loaded on the BHCS modified glassy carbonelectrode by one-step electrodeposition to obtain Au NDs/BHCS/GC electrode as a selective and sensitiveelectrochemical sensor for detecting morphine at low concentration. The proposed electrochemical sensorexhibited a highly selective assay for monitoring of MOR with a wide dynamic linear range ۰.۰۱–۳۰۰ μM,accompanied by a low detection limit of ۸.۳ nM. In addition, the proposed electrochemical sensor hadsatisfactory interference rejection and good stability
