  Author(s): Mauricio Chase*, Sarah Fieldhouse, Stephen Bleay and Neil Lamont
  
  This review synthesizes current knowledge on the use of Acid Dyes (ADs) Acid Black 1 (AB1), Acid Yellow 7 (AY7), and Acid Violet 17 (AV17) identified by the UK home office as common enhancement agents for blood-contaminated fingermark impressions. Various factors which can influence AD bloodmark enhancement are reported in scientific literature, including sequence of application, time and temperature, dye formulation, substrate features, processing times and bloodmark volume, contaminants, fingermark age, deposition pressure and donor variation. While these dyes have demonstrated excellent capability on porous (excluding AY7) and non-porous substrates, this review has identified several gaps in understanding and application. Firstly, the effect of blood volume on the fixing and staining times of these dyes, particularly for marks associated with high volumes of blood, requires explora.. Read More»
