Scientists at the National Centre for Forensic Science at the University of Central Florida have developed a novel blood analysis technique using Implen's Nanophotometer.
According to Implen, there is generally no accepted procedure that enables forensic scientists to determine the age of blood stains at a crime scene.
Present methods are either limited in their predictive power or their analytical sensitivity.
However, the University of Central Florida, through grants from the US National Institute of Justice and the Forensic Technologies Centre of Excellence (FTCoE), Florida, have identified a novel hypsochromic shift of the Soret band of haemoglobin that allows for bloodstains to be distinguished by age in terms of minutes, hours, days, weeks or months.
To be fully effective the analysis should be performed at the actual crime scene.
The Nanophotometer from Implen was selected for this purpose.
Its portability, its low-volume capability and its overall analytical performance were main arguments for the evaluation.
The Implen Nanophotometer is also suitable for the quantification of DNA following extraction, enzymatic activity or protein quantification.
