(A). Growth of peptide fiber cross-section area, Sc, at different ionic strengths. The lines represent a basic B-spline fit of the data. Violet: Gel-1, green: Gel-2, blue: Gel-3, red: Gel-4, wine: Gel-5. (B). Dependence of peptide fiber cross-section area, Sc (z-axis), on time and ionic strength (x- and y-axis). 3D plot is made using Origin 8.1 (OriginLab) software, wireframe created using thin plate spline (TPS) algorithm.
