摘      要：Chirality is one of the most remarkable geometrical properties with a variety of manifestations in the material *** discovery of chirality in inorganic nanostructures spurred the rapid growth of fundamental and applied studies involving chiral nanoscale particles in chemistry,biology,medicine,and *** many factors make chiral inorganic nanostructures significant to researchers from many backgrounds,the unique characteristic that drives research in this area is their ability to exhibit high chiroptical *** this review,we specifically address its origin in juxtaposition with chiral organic *** activity depends on multiple factors,including the degree of asymmetry and the size of the object,compared with light ***,it is the high polarizability that distinguishes chiral inorganic matter from what is known from organic chemistry and *** importantly,strong light-matter interaction between chiral nanostructures and circularly polarized photons has direct implications for the long-standing fundamental questions about the origin of homochirality on earth and new possibilities for chiral *** insight into chiroptical activity also deepens the existing knowledge about the nanoscale matter and expands its technological applications.
