【摘要】 针对犯罪现场遗留在多色、潮湿的客体表面的油脂类潜在手印,荧光微粒悬浮液技术可以有效解决客体背景干扰、物面潮湿带来的问题。本文先后探讨了碱性黄-17作为显现主体的微粒悬浮液显现手印的最佳浓度、显现时间、表面活性剂的选择及浓度、体系酸碱度、在不同客体表面的显现情况、不同放置时间以及不同浸泡时间下的显现情况,最后确定碱性黄-17微粒悬浮液的最佳显现配方以及显现应用情况。更多还原

【Abstract】 For greasy latent prints left on multicolored,damp surfaces at crime scenes,fluorescent particle suspension technology effectively addresses issues caused by background interference and surface moisture.This paper systematically investigates the optimal concentration of Basic Yellow-17 as the developing agent in the particle suspension for fingerprint development.Key parameters were examined,including development time,selection and concentration of surfactants,system pH,development performance on various object surfaces,and development outcomes under different holding times and immersion durations.Ultimately,the optimal formulation and application conditions for the Basic Yellow-17 particle suspension were determined.更多还原
