Structural-spectroscopic analysis of DFO/PVA films as potential materials used in revealing fingerprints on non-porous surfaces.
Keyword(s):
1,8-diazafluoren-9-one (DFO) is a sensitive luminescent probe targeting α-amino acids. The study described herein exploited its physicochemical properties to form DFO/PVA polymer films. As a result, materials with stable and reactive DFO were obtained. Spectroscopic analysis of the formed films showed that the films with the highest concentration of DFO exhibited the highest reactivity. Novel materials in the form of thin DFO/PVA films with potential applications for revealing fingerprints on non-porous surfaces were obtained.
