a–d The morphology changes depend on the reversible photoisomerization of the Azo-SO3H from E-Isomer (echinocyte, (a) and (c)) to Z-Isomer (discocyte-like, (b) and (d)). e Quantification of the inhomogeneity of N = 3, n = 13 RBCs via the standard deviation of the pixel values. The difference between the discocyte-like and echinocyte is significant (two-sided t test, p = 7 × 10−7).
