In this communication, we report on the significant enhancement of latent fingerprints by the deposition of CTFs on two nonporous surfaces: smooth glass slides and rough aluminum sheets, both of which are window and door materials, and likely to be touched in a crime scene. Further, it has been reported that fingerprint residues adhere strongly to smooth surfaces such as PVC window shutters and powder-coated aluminum window frames, and may last for a long time under harsh conditions [26]. The glass and aluminum surfaces are very different optically in that the rough aluminum surface is highly reflective as well as highly scattering, making even the detection of fingerprints on the surface very difficult in comparison to the glass surface. Calcium fluoride (CaF2) and silica (SiO2) were vapor deposited at large oblique angles by electron beam vaporization. Only oblique angle deposition without rotation of the substrate was carried out and resulted in making both the presence and details of the fingerprint highly visible on both the surfaces. Subsequent treatment by fluorescent dyes (Rhodamine 6G) or 1,2-indanedione-alanine, resulted in the fingerprints with CTF growth becoming highly visible under a fluorescence microscope. The reaction product of 1,2-indanedione with amino-acids such as alanine that are present in a fingerprint is fluorescent. In comparison, fingerprints without CTF deposited on them could hardly be detected on these surfaces even when treated with these fluorescent reagents. The CTFs appear to localize and entrench the dye within them by drawing the dye solutions into them by strong capillarity caused by their nanoporosity. The development and visual enhancement of fingerprints using CTF deposition followed by fluorescent reagents is an original development that has immense potential for fingerprint development techniques.
