Electrochemical impedance spectroscopy: a deeper and quantitative insight into the fingermarks physical modifications over time

Fingermarks found at the crime scene undoubtedly represent one of the most important forms of physical evidence of paramount forensic relevance. Although significant progresses have been achieved in recent years in the field of latent fingermarks development, as a result of astonishing advancements in the field of nanotechnology [1–4], as well as in immunological detection techniques [5–7], there is still increasingly need for enhancements in sensitivity and specificity, as recently underlined by several researchers [8,9], in order to reduce the number of fingermarks remaining undetected.
