Glycofullerene Characterization by TEM

Check if the same lab product or an alternative is used in the 5 most similar protocols

Transmission electron microscopy (TEM) was performed by using a JEOL microscope (Model JEM-2100) (JEOL Ltd., Tokyo, Japan) operated at 200 keV to analyze the sizes and dispersion of the synthetic glycofullerenes. A drop of the glycofullerenes solution (~1 μL) was dropped on a carbon-coated 200-mesh copper grid. The grid was left to dry at room temperature for hours. Before the TEM analysis, the grid was then further dried under vacuum overnight.

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.
