Abstract: As an emerging chemical tracer technology, the hydrogen and oxygen stable isotopes have a wide range of applications in geoscience, environmental ecology and forensic science. The fingernail, a new type of biomarker, possess a high evidence and application value in forensic science and its analytical potential is gradually being tapped. The paper conducted a review from basic principle of hydrogen and oxygen stable isotopes traceability, pretreatment methods and determination methods in human fingernails and the application in forensic science. Besides, a brief prospect was also given about its development.
