YFBS mimics human blood, with remarkable similarities in luminol reactivity and spatter patterns. YFBS replicates the luminol reaction while preserving key rheological properties of real blood. YFBS shows minimal visual differences from other substitutes, enabling realistic applications. YFBS is ideal for studies needing both chemical and physical properties of real human blood. 1 INTRODUCTION Crime scenes often contain various types of biological evidence, such as saliva, semen, and hair.
