The application of silicon sol –gel technology to forensic blood substitute development: Investigation of the spreading dynamics onto a paper surface

The Organization of Scientific Areas Committee ’s (OSAC) bloodstain pattern analysis (BPA) subcommittee has recently reported a call to determine the differences between fresh, whole human blood and various blood substitutes for use in research, training and case experimentation [1]. The subcommittee suggests that further research can help wit h understanding the relationship between the physical characteristics of blood and other fluids and the mechanisms that cause pattern formation [1]. This work complements this idea by exploring the contributions of surface tension, density and viscosity to droplet spread and passive drip stain forma tion of various forensic blood substitutes (FBS).
