Strontium is a chemical element without biological functions in humans. In fact, only two biological roles are known, both as a biomineral constituent. However, strontium and calcium (a significant biometal) present chemical similarities; hence, the absorption of the former by living organisms is plausible. Based on the particular properties of isotopes of strontium several applications of this chemical element in biological sciences have been developed. These include its radioactive and non-radioactive isotopes in medical applications or resorting to its stable isotopes as analytical tools in isotope fingerprinting (Sr-87/Sr-86) to study dietary habits and migration patterns of ancient populations, food authentication and forensic sciences. This article, reviews papers published between 2012 and 2016, highlights the use of strontium isotope ratios for such biological related applications and compiles an analytical database, providing a valuable tool for future studies in the area.
