In the realm of materials science, an extraordinary innovation is emerging that combines the precision of nanotechnology with the elegance of DNA self-assembly. Researchers are pushing the boundaries of what is possible by constructing nanoparticle quasicrystals using DNA as a scaffold. In this article, we will delve into the fascinating world of nanoparticle quasicrystals, explore their unique properties, and understand how DNA is harnessed as a tool to create these groundbreaking structures.
Quasicrystals: Beyond the Ordinary
Quasicrystals are a class of materials that defy the conventions of traditional crystallography. Unlike the regular repeating patterns found in conventional crystals, quasicrystals exhibit non-repeating, aperiodic structures that offer a unique set of properties. Their discovery in the 1980s by Dan Shechtman, which later earned him the Nobel Prize in Chemistry, opened up a new chapter in materials science.
Aperiodic Symmetry
The defining feature of quasicrystals is their aperiodic symmetry, meaning they lack the periodic repetition of atoms found in regular crystals. This property leads to unique and advantageous physical properties.
