摘要: An examination protocol for rapid detection of remnants blood particles on garments suspects in bloody murder cases is described. Microparticles are sampled along with fibres and hairs using the tape lifting method. The tapings searched a low power microscope red morphology similar to blood. Presumed traces further examined microspectrophotometry cut out piece taping. typical visible spectrum haemoglobin characteristic Alternatively Raman spectroscopy can be used measure vibrational haemoglobin. At later stage, these may removed from taping order extract attempt obtain genetic profile.
