Figure 4. Enhancing the spectra by modifying the capillary tip.
(a) The vesicle diameter varies from 100-500 nm depending on the membrane’s origin, therefore a capillary cut in the standard way (LH panel), may not allow for sufficient exit of vesicles, and may require further opening (RH panel). Scale bar is 1 mm. (b) Scanning electron microscopy of the capillary tips cut in the standard way (LH panel) and further broken (RH panel). Scale bar is 1 μm.
