Abstract

A new technique to develop a latent sebaceous fingerprint for visualization requires the macroscopically conformal deposition of a columnar thin film on top of the fingerprint. In order to correlate the thin-film morphology to the quality of development, dense thin films as well as films comprising either upright or tilted nanocolumns were deposited on multiple samples of the same fingerprint from a donor. According to an objective grading scheme, films with upright nanocolumns provided the best development while dense films provided the worst development.
