The above discussions are further supported using the TEM study, as shown in Figure . Here, two different potencies (low and high) are used to understand the morphology (size, shape etc.) and chemical composition of the particles. Figure shows the TEM and high-resolution TEM (HRTEM) images of a low potency sample with different size distribution. It is observed that Au NPs are embedded in the carbon layer. Figure shows that the Au NPs are distributed on the carbon layer. The carbon layer is formed from the sugar of milk (sucrose, glucose, fructose etc.).
