Highlights
I t has come to our attention that some of our cryo-electron microscopy images show ice contamination,[1] instead of the soft matter aggregates originally indicated in our publication
Our overall conclusions based on complementary cryo-electron microscopy (cryo-EM), DLS, CAC, and fluorescence spectroscopy measurements are unaffected
In re-examining our cryo-EM data set, we found micrographs showing additional structures that are unlikely to be contaminants, which we previously took as less representative
Summary
I t has come to our attention that some of our cryo-electron microscopy (cryo-EM) images show ice contamination,[1] instead of the soft matter aggregates originally indicated in our publication. The images only relate to counterexample peptoid sequences that did not properly assemble (originally Figures 3D−K and S5E−G, I−M, and P). The mean sizes of these structures (50−250 nm in diameter, depending on sequence) fit better with our complementary DLS results no agglomeration effect of individual 5−20 nm ice artifacts is needed anymore to reconcile the sizes measured by EM and DLS. The corrections in the main text on page 496 (third page) are as follows (main changes in bold): In the bottom left paragraph below Figure 3, the corrected second sentence should read: “N(FKF), which has Nlys with the longer side chain in the same central residue position as N(FkF), formed globular assemblies ca. In the right column, the corrected bottom paragraph should read: “Peptoid N(FKF) shows assemblies with RH
