Fig. 1: Scheme of the whole process from protein fibrils formation in droplet with confined convective flow field control and study of droplet contact line depinning dynamics to protein fibrils molecular structure characterizations.

a Protein fibrils formation with temperature gradient (ΔT) controlled confined convective flow field in droplet on SHS. b Droplet contact line depinning dynamics study with ultra-fast imaging. c In situ molecular structure characterizations of protein fibrils with Raman, XRD, 2D-WAXS, and molecular dynamics (MD) calculation.
