Method for Colloidal Diamond Construction Unlocks Long-Coveted and Wide-Ranging Photonic Potential
NEW YORK, Oct. 7, 2020 — Researchers in David Pine’s NYU laboratory have developed and introduced a method for the reliable creation of colloidal diamonds. Using a steric interlock mechanism to spontaneously produce the staggered bonds that make a physical diamond formation possible, the researchers created pyramidal colloids that approached and subsequently linked to one another in an orientation necessary to the self-assembly of a diamond formation. Colloids, if assembled and arranged in a diamond
