title: The use of microspectrophotometry to characterize microscopic amounts of blood.
abstract: The use of a Nanospec 10 S microspectrophotometer to examine minute bloodstains is discussed. To satisfy criteria for chemical identity, absorption spectra were recorded before and after treatment of the blood with Takayama reagent. The technique is of value where only tiny particulate bloodstains are available for testing and in other specialized instances.
