Figure 2From: Chloroplasts-mediated biosynthesis of nanoscale Au-Ag alloy for 2-butanone assay based on electrochemical sensorTEM and HR-TEM images. (A) TEM images of Au-Ag alloy: the inset was the corresponding SAED patterns, (B) high-magnification TEM images, (C) HR-TEM image of single Au-Ag alloy particle, and (D) energy dispersive X-ray spectroscopy measurement profiles.Back to article page
