Chiral separation at nano scale is gaining importance in drugs development, proteomic, genomic and environmental sciences. Generally, traces of drugs are found in our body for several weeks. These cannot be detected by conventional analytical techniques. The present article discusses the advances in chiral resolution at nano scale using nano liquid chromatography (NLC) and nano capillary electrophoresis (NCE). The instrumentation, chiral selectors, mechanisms of chiral recognition and future challenges and prospectives have been discussed.
