However, images are not opening at their normal sizes but i would like to confirm whether all three images are from the same self-assembled peptide or they are different samples?

This product may occur due to variations in process variables or environmental factors. Therefore it is not assured that none of these factors.

Similar cases were observed in the production of nanoparticles.

Thanks all for your reply! It is the same peptide with different magnification power! using gluteraldehyde or without!

Thank you for your reply! what do you recommend me to do so I can get better images?

To get better image you just simply keep trying. This is simply a matter of experience. the more you do it will be easier to get the desired results.

After you get the best image you can get from SEM, you can use software such as ImageJ to process your image.
