摘要
目的探索显现潮湿纸张表面油脂手印的显现方法。方法取250枚纸张载体的油脂指印,分为AB-CDE 5组,分别用自来水浸泡不同时间后,用尼罗红工作液显现,并在465nm多波段光源下进行观察。结果 5组的显现率从56%～94%,表明显出率比较高。结论该方法简单实用,可用于案件检验。
Objective To explore a new method for developing oil fingerprint on wet paper.Methods 250 oil fingerprints on wet paper and dry paper was treated with Nile red solution of sodium hydroxide and Nile red solution of ethanol,and then was observed under 465nm light.Results The fingerprints on both dry and wet paper were detected with the success rate ranged from 56%~94%.Conclusion Nile red is an easy method for developing latent fingerprint on paper and can be used in casework.
