Towards noninvasive drug distribution in tissues: coherent Raman microspectroscopy of chiral molecules
Additional Document Info
2017 SPIE. Many biologically active molecules are chiral. Many drugs, which are currently in use, are supplied as an equimolar mixture of enantiomers. Although they have the same chemical structure, i.e. are not distinguishable by conventional Raman spectroscopy, most isomers of chiral drugs exhibit marked differences in biological activities such as pharmacology, toxicology, pharmacokinetics, metabolism, etc. In this report we introduced a new spectroscopic tool to extend nonlinear Raman spectroscopy to chiral substances.
