Completely disordered systems are suitable for large‐scale fabrication and may host non‐trivial optical properties. In article number 2000151 by Victor S. Asadchy, Shanhui Fan, and co‐workers, the designed colloid metamaterial exhibits isotropic chirality three orders of magnitude larger than known natural and artificial materials. Such giant chirality is achieved through dense packing of dielectric clusters without inversion symmetry, which in turn possible thanks to suppressed absorption and incoherent scattering in the colloid.

胶体超材料：具有巨大各向同性光学活性的三维随机介电胶体超材料（激光光子，修订版14（10）/ 2020）

完全无序的系统适用于大规模制造，并且可能具有非平凡的光学特性。在Victor S. Asadchy，范善辉和他的同事们的文章编号2000151中，设计的胶体超材料表现出的各向同性手性比已知的天然和人工材料大三个数量级。这种巨大的手征性是通过电介质簇的密集堆积而没有反转对称性而实现的，而这又归因于胶体中吸收和不相干散射的抑制。
