Nanofiber diameter characterization is a tedious work. Generally researchers take a snapshot of nanofiber collection, then use image analysis software (such as ImageJ) to manually measure fiber diameters. Quicker and more reliable techniques should be developed for online quality control.

Here are some other methods:
