This study aimed to compare effectiveness of fluorescent reagents for enhancing blood such as acid yellow 7, rhodamine 6G, eosin Y. AY7 and eosin Y have been introduced in Korea as fluorescent reagents for enhancing blood, but not rhodamine 6G. In this study, researchers photographed when each reagents gave the most effective results. Consequently, rhodamine 6G was superior to the others. Eosin Y enhanced bloody fingermarks weakly compared to AY7 and rhodamine 6G. Furthermore, the more depletion trials were done, the less effectiveness were shown. Therefore, researchers recommended that crime scene investigators try to use rhodamine 6G fluorescent reagents for enhancing blood.
