While I was measuring PDI of the prepared liposomes, I had values, ranging from 1.55±0.38 and 3.66±2.34. It is known that PDI should have values below 0.7. But in my case, I had values > 0.7. Can anyone help me by explaining this?

Thanks in advance!

Hi Ahmed,
I'm guessing that you used dynamic light scattering (DLS) e.g. the Malvern Zetasizer Nano system to measure size? If so, the result you get for size is the 'Z-average' or 'Cumulants mean' and the programme also gives you a PDI value. For the projects that I have been involved in, we were happy with PDI values well below 1 (usually
