摘要
指纹在法医鉴定及人身识别方面承担着重要作用,同时广泛应用于日常生活中的安全检验、访问控制、个人认证等领域。当前尽管指纹显现方法繁多,但是仍然需要一种技术简单、快速、容易操作的方法对指纹进行显现。本文基于选择性空间控制鲁米诺在电极表面的电化学发光行为,构建了一种潜在指纹的反相成像技术。考察了共反应剂种类、施加电位以及发光体浓度对指纹显现效果的影响。该成像方法具有简单、快速以及无需对基底或样本进行处理等优点,为指纹显现和电化学成像技术提供了一种新方法和新思路。
Fingerprints function as an indispensable tool in forensic investigations and personal identification, as well as in our daily life for many other purposes, such as safety inspection, access control, and individual credentials. To date, although innumerable methods have been exploited for fingerprint detection, a simple, rapid, and easy-processing method is still needed. Herein a negative imaging approach for developing latent fingerprints was presented, based on spatial selective control of electrochemiluminescence generation of luminol at the electrode surface. Factors, including the co-reactants, applied potential and the concentration of ECL luminophore, were investigated to achieve a satisfactory visualization enhancement. This imaging approach is simple, rapid, and no pretreatment either on the background or on the fingerprint itself is needed. It constitutes a new approach and new idea for both fingerprint development and electrochemical imaging technique.
