    Extended Data Fig. 1 Cryo-TEM microscope micrograph.

    The control micrograph of a 10 mM precursor 2 stock solution excludes preassembly of the inactivated precursor in the absence of EDC fuel.

    Extended Data Fig. 2 EDC hydrolysis and Fmoc deprotection kinetics.

    a , b , The addition of the quenching solution freezes the reaction cycle of Fmoc-E-OH ( 1 ) ( a ) and Fmoc-AAD-OH ( 2 ) ( b ). In the timescale of the HPLC analysis, the degradation of EDC and Fmoc deprotection does not falsify the concentration determination.

    Extended Data Fig. 3 The absorbance of light as a measure for turbidity.

    a , Usage of different sample containers affects the measurement quality as sedimentation in a 96-well plate wrongly extends the system’s lifetime. b , Regarding colloids formed by 1 , a cuvette is a better choice as sample container.
