The term chiral describes two structures, such as molecules and nanoparticles, which are non-superimposable mirror images with sole symmetry operation E: 360-degree rotation about an axis. Chiral molecules are optically active enantiomers, meaning they rotate plane polarized light, and may be analyzed with circular dichroism (CD) instrumentation. Diastereomers include achiral compounds which are superimposable to its mirror image, and may possess an internal line or plane of symmetry in addition to E. The study of chiral molecules is valuable in that it connects topics for undergraduates and graduates in the courses of organic chemistry, inorganic chemistry, and instrumental analysis, while providing applications in real-world fields. This review covers the introduction to inorganic chiral nanostructures, which are valuable in pharmacokinetics and chemical analysis methods. Chemical applications also include separation for enantiomeric selectivity, catalysis based on surface ligand characterization, and sensing chiral molecules from altered single-walled carbon nanotubes (R- or L-SWNTs).
