Figure 3. Tolerance of peptoid membrane structures to incorporation of functional objects.

(a) Membrane-forming peptoids containing a wide range of functional objects as side chains at a number of locations, in which nine functional objects were used and listed. (b) AFM image of one 2D nanomembrane assembled from 1-Npyr-Pep-2. (c) X-ray diffraction data of membranes assembled from 1-Npyr-Pep-2, 1,8-(Ntyr)₂-Pep-2 and 13-Nte-Pep-2 are similar to the X-ray diffraction data of Pep-2, which shows that the core structure is retained.
