Comparing Liposome Size: DLS Measurement vs. SEM Observation with Air Drying ?

I have an issue with SEM imaging of liposomes. When measured by DLS, they appear to be around 120 nm, but when using SEM with simple air drying, they appear much larger, around one micrometer.

What is the reason of appearance of 2 or 3 peaks in zeta potential analysis of sample?

Hello I have prepared metal nanoparticles and did zeta potential. Normally there is a single peak in sample but now there are 3 peaks. I prepared sample for analysis first I prepared 10 mg/mL...
