Effect of bead sizes on the pitch angle of EMACs

Here I'd to show a few photos of EMACs to how the ratio of two kind of bead sizes on the pitch angles.

1. Correct pitch angle by using 8mm and 6mm beads.


2. Ligands spiral around the central metal string too fast if we use the same kind of beads for both ligands and metal string.


3. No pitch angle if we use 10mm and 14mm beads.
