(a) The anti-CRP-coated nanobeads’ diffusion coefficient measured by smartphone-based diffusometry in different CRP solutions. (b) After repeating the analysis three times, the values of the nanobeads’ diffusion coefficients in an equilibrium state showed a linear decrease in the concentration range of 1~8 µg/ml (n = 3).
