The helical twisting power of neat as well as several surface‐functionalized cellulose nanocrystals (CNCs*), exhibiting innate molecular and structural chirality, was evaluated in a nematic liquid crystal as a reporter medium. In their Communication on page 17344, Diana P. N. Gonçalves and Torsten Hegmann report that all CNC* species were able to induce and amplify chirality at the nanoscale level, especially those functionalized with mesogenic molecules that better resembled the N‐LC host molecules. Surface functionalization with chiral molecules did not appear to enhance the helical twisting power of the CNCs, thereby supporting the role of innate nanocrystal core chirality.
