Use of an optimized 1,2-indanedione process for the development of latent prints*.

Danna E Bicknell et al.

Journal of forensic sciences, 53(5), 1108-1116 (2008-07-22)

1,2-Indanedione belongs to a class of compounds which have demonstrated great potential in the processing of latent prints, particularly in the area of fluorescence. However, variability in results achieved worldwide has precluded it from being used extensively. In order to

The Luminescence of 1,8-Diazafluoren-9-One/Titanium Dioxide Composite Thin Films for Optical Application.

Aneta Lewkowicz et al.

Materials (Basel, Switzerland), 13(13) (2020-07-10)

The investigation of innovative label-free α-amino acids detection methods represents a crucial step for the early diagnosis of several diseases. While 1,8-diazafluoren-9-one (DFO) is known in forensic application because of the fluorescent products by reacting with the amino acids present

Study of the reaction mechanism of 1,8-diazafluoren-9-one with the amino acid, L-alanine.

D Wilkinson

Forensic science international, 109(2), 87-103 (2000-03-08)

This paper describes the study of the reaction between 1, 8-diazafluoren-9-one (DFO) with the amino acid L-alanine in methyl alcohol. Particular interest was paid to the possible role of the solvent which appears to react with the DFO to form

An evaluation of the effect of incorporating metal salts into 1,8 diazafluoren-9-one (DFO) formulations for fingermark enhancement.

Kelly Mayse et al.

Science & justice : journal of the Forensic Science Society, 59(3), 349-358 (2019-05-06)

A study into the modification of 1,8-diazafluoren-9-one (DFO) formulations by the additions of metal salts into the working solution is reported. Similar additions have been found to increase the fluorescence of marks developed using other amino acid reagents including 1,2-indandione

Luminescent visualization of latent fingerprints by direct reaction with a lanthanide shift reagent.

J P Caldwell et al.

Journal of forensic sciences, 46(6), 1332-1341 (2001-11-21)

The utilization of the lanthanide shift reagent tris (6,6,7,7,8,8,8-heptafluoro-2,2-dimethyl-3,5-octanedionato) europium (III) [Eu(fod)3] as a simple one-step reagent for the luminescent visualization of latent fingerprints has been investigated. UV excitation of Eu(fod)3-treated prints, achieved by using a hand-held UV lamp or

Enhancement of ninhydrin- or DFO-treated latent fingerprints on thermal paper.

Lothar Schwarz et al.

Journal of forensic sciences, 52(3), 649-655 (2007-04-26)

A new method for enhancement of ninhydrin or 1,8-diazafluoren-9-one (DFO)-treated latent fingerprints on thermal paper will be described. Most thermosensitive surfaces of thermal paper become dark when treated with DFO or ninhydrin petroleum ether (NPB) solution. This effect minimizes contrast
