Figure 2.

Protein mixtures deposits formed at different relative concentration. (a) Deposits containing proteins mixture of BSA-LYZ. Relative protein concentration ϕ_r = 0:1, 1:5, 1:1, 5:1, 1:0, protein contraction ϕ_p = 1.6 wt%, and NaCl concentration ϕ = 1 wt%. The droplet evaporation was carry out on a solid surface at T = 37 °C. (b) Zoom at representative patterns in the deposits. The corresponding texture analysis (c) FOS (Mean, Standard Deviation, Integrated density, Skewness and Kurtosis) and (d) GLCM (Energy, Inertia, Correlation, IDM and Entropy). Black squares and red circles correspond to proteins deposits at ϕ = 0.5 and 1 wt%, respectively). The error bars correspond to standard deviations from n = 24.
