When our Applied Science Forensic Science students heard that something nasty had been found in the woods, they donned their protective clothing and started a Scene of Crime investigation. Students Emily Iggulden and Tom Wills led the investigation, and the team was soon embarking on a detailed examination of the area, with meticulous recording of any items discovered.
Back in the labs, they’ll be analysing forensic evidence: carrying out handwriting analyses on any papers found and chromatography on the ink; and looking for fingerprints on any weapons recovered from the scene. If they find any human cells such as in blood and saliva, they will be able to carry out electrophoresis to produce a DNA fingerprint. Electrophoresis uses an electrical field to move the negatively charged DNA towards a positive electrode through an agarose gel matrix.
