摘要

Fingerprinting has been used for over 100 years,especially for forensic investigations,personal identification,and law enforcement [1].Although reagent-based detection of fingerprints has been used since it was introduced in the 1880's,this technique has several shortcomings,such as the use of harmful reagents,laborious protocols,and the destruction of samples.Recent advances in analytical instrumentation have enabled the detection of fingerprints using sophisticated instruments,such as the scanning electron microscope and mass spectrometer.However,these instrumental methods require trained operators and are costly.
