Kinetics of the interface formation for dilute and condensate states of synapsin 1. Measurements of the change in the electron concentration as a function of time Δe^–(t). The analyte droplets are introduced to the interface of the Gr FETs at 0 s. Each data set is averaged between three FETs and the error bars represent standard deviation. Measured currents are expressed as a relative charge in the charge concentration and are normalized to the active area of each device. (a) A comparison of synapsin full length (FL) in dilute and condensate states. (b) Same as in a only with synapsin intrinsically disordered region (IDR). (c) A reference experiment measuring the response of the devices exposed to a buffer solution without or with the crowding reagent. Of note, the scales in b and c are set the same for clearer comparison.
