Focused on Engineering research news, this establishment highlights papers of exceptional scientific importance to a broad scientific and engineering, and its contents are mainly targeted to an educated audience of engineering and physics professionals and students, being viewed almost 650,000 times each month by engineers, professors and scientists.

Throughout this work, the research staff led by Professors Ricardo Riguera and Emilio Quiñoá show that the combination of these concepts with the Sergeants and Soldiers effect allows to extend those results to different copolymers and therefore, to the preparation of a wide scope of macroscopically chiral nanostructures with different functionalities and P or M helical senses.

The mechanistic explanation is based on the addition of Ag+ or Na+ ions that are complexed by the scarce (R)-MPA units in the copolymer (minor component). The Sergeant character acquired by those units command the adoption of either the P or the M helix in the rest of the chain formed by the non-chiral monomers (i.e., the Soldiers), depending on the amount of MeOH or MeCN employed
