Suspensions of lyophilized samples in distilled water were diluted, dropped onto aluminum stubs, and dried for 48 h under vacuum. In order to induce electrical conduction, samples were coated with a fine layer of gold under vacuum, using a sputter coater. Coated samples were analyzed on a ZEISS SIGMA 03-39 Field Emission Scanning Electron Microscope at 5–15 kV acceleration voltage under an argon atmosphere.
Sigma 03 39 field emission scanning electron microscope
Manufactured by Zeiss
Sourced in Germany
The SIGMA 03-39 Field Emission Scanning Electron Microscope is a high-performance laboratory instrument designed for advanced imaging and analysis of materials at the nanoscale. It utilizes a field emission electron source to produce a high-brightness, high-resolution electron beam for detailed investigation of surface topography and composition.

Lyophilized samples were re-dispersed in distilled water and a drop of each sample was placed on aluminium stubs and dried for 48 h. Solid samples were mounted on double sided carbon tape. In order to induce electrical conduction, samples were coated in a vacuum with a fine layer of gold using a sputter coater. Each sample was then analysed on a SIGMA 03-39 field emission scanning electron microscope (Zeiss, Jena, Germany) at 5–15 kV acceleration voltage under an argon atmosphere.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
