In this paper, we demonstrate an electrical detection technique based on solution processed zinc oxide nanosphere for ultra-low level detection of bovine serum albumin (BSA). Our sensor device works on the basis of the variation of conductance of the ZnO nanosphere with different concentration of BSA. The morphological and structural characterizations of ZnO nanosphere were carried out by transmission electron microscopy (TEM), scanning electron microscopy (SEM), and X-ray diffraction (XRD… CONTINUE READING
