Blood Droplet Drying on Inclined Surfaces Reveals Novel Cracking Patterns
2025-05-01
A new study unveils asymmetric deposits and cracking patterns formed during the drying of blood droplets on inclined surfaces. Gravity's influence on red blood cell distribution leads to thicker deposits and coarser cracks on the downhill side, contrasting with the uphill side. This research is significant for forensic bloodstain pattern analysis, as surface tilt and droplet size significantly alter the resulting patterns, potentially leading to misinterpretations if ignored.
