潜在指纹(LFP)可能包含比对象的简单身份识别更多的法医信息；它们可能包含与爆炸物或滥用物质接触的证据。化学信息在解析来自不同个体的重叠的LFP时也是有用的。我们用解吸电喷雾电离质谱仪以成像方式记录了化合物特有的化学指纹图谱。
Latent fingerprints (LFPs) potentially contain more forensic information than the simple identification of the subject; they may contain evidence of contacts with explosives or substances of abuse. Chemical information can also be useful in resolving overlapping LFPs from different individuals. We used desorption electrospray ionization mass spectrometry in an imaging mode to record compound-specific chemical fingerprints.
