“…This indicates that the treatment of samples did not result in any inhibition for the PCR. These results reflect other studies [49][50][51][52][53][54] which reported that reagents commonly used to develop latent marks do not adversely affect subsequent recovery of DNA.…”

“…With fingermarks enhancement, several studies [49][50][51][52][53][54] have shown that most of the reagents commonly used to develop latent marks, such as aluminium powder, black magnetic powder, fluorescent powders, wet powder suspension and 1,2-indanedione do not affect subsequent recovery of DNA. Other specific chemicals such as cyanoacrylate and ninhydrin may have a negative impact on the process as they can either degrade or sequester the DNA or inhibit the PCR reaction [55,56].…”

The effect of mark enhancement techniques on the presumptive and confirmatory tests for blood

An investigation into the effects of physical and chemical enhancement on subsequent presumptive and confirmatory tests for human blood is presented. Human blood was deposited onto porous (white 80gsm paper and brown envelope) and non-porous (tile and linoleum) substrates in a depletion series (30 depletions on non-porous and 20 on porous) and subjected to three ageing periods; 1, 7 and 28 days. A number of enhancement techniques were tested [fluorescence, black magnetic powder (BMP), iron-oxide black powder suspension (PS), cyanoacrylate (CA) fuming, acid violet 17 (AV17), acid yellow 7 (AY7), ninhydrin, DFO and Bluestar Forensic Magnum (BFM) luminol] to evaluate their potential effects on subsequent presumptive and confirmatory tests. AV17 and Bluestar provided the best enhancement and fully enhanced all depletions in the series. The sensitivity of the Kastle-Meyer (KM) (presumptive), Takayama and RSID-Blood tests (confirmatory) was initially investigated to determine the range of detectable depletions. The KM test detected all depletions, whereas the Takayama test detected up to depletion 6 and RSID-Blood detected up to depletion 20 (paper), 10 (envelope), 15 (tile) and 9 (lino). The abilities of these tests to detect blood after enhancement were then observed.A number of techniques resulted in little to no effect on any of the blood tests, whereas adverse effects were observed for others. Ninhydrin and CA fuming caused weak but instantaneous positive KM results whereas methanol-based AV17 and AY7 delayed the reaction by as much as 1 minute. The Takayama test was not very sensitive, therefore, its performance was easily affected by enhancement and negative results were often observed. RSID-Blood tests were largely unaffected by chemical enhancement although a drop in positive results was observed for some of the techniques when compared to positive controls.Using a standard procedure for DNA extraction, all the tested blood samples (before and after enhancement) gave a detectable quantity of DNA and were successfully profiled. Out of the 45 samples processed for DNA profiling, 44 gave full profiles, while the remaining showed allele drop out in one or two loci.

Latent fingerprints are the finger skin impressions in a groove and ridge pattern left when fingertips come in contact with any surface. In forensics investigation, latent fingerprints plays as principal evidence to identify and convict criminals. Due to the presence of overlapping noisy patterns and complex ridge structure, they are usually unclear and of poor quality. The discipline of latent fingerprint detection has gain attention of many researchers over the years and many advances have been made but it is still challenging to accomplish the task by offering a quick, reliable and accurate latent fingerprint detection system. The presence of spoiled minutiae information, ridge and overlapping patterns make the task more complicated. The latent fingerprints do not serve any purpose before the enhancement and reconstruction of the ridge patterns, minutiae information and their quality. Prior to latent fingerprint detection and feature extraction, latent fingerprint enhancement is absolutely requisite to improve the quality for accurate fingerprint detection. This paper presents an analysis of various latent fingerprint enhancement techniques by comparing the work of numerous researchers. The paper sheds some light on the issues and challenges in the process of latent fingerprint detection. In addition, the paper also presents various datasets available for latent fingerprint detection.

“…Discussion: The good performance of sticky notes in the ninhydrin test compared to other techniques may be due to extraction removing sampled Ruhemann's purple, a suspected amplification inhibitor [5]. Reduced profile completeness across all techniques in the ninhydrin test may be due to physical removal of DNA during the ninhydrin wash step: the similar wash step of coumassie blue staining causes such reduction [6]. Reduced profile completeness in the confirmatory study may be due to considerably less starting material for analysis, with only halfprints used.…”

The sampling of touch DNA from paper documents is often achieved by simply excising pieces of the document. This generates high-quality DNA profiles but also damages evidence; thus, we investigated non-destructive sampling of paper documents for touch DNA. Exploratory and confirmatory studies were performed to identify a non-destructive technique that generated excision-comparable STR profiles. Sampling with adhesive portions of sticky notes performed well in the initial exploratory study: in the confirmatory study this adhesive-based technique generated profiles of comparable completeness to conventional excision, with no significant difference in profile completeness found between the two. The sticky-note technique performs comparably to excision in generating STR profiles from paper, whilst preserving exhibit integrity.
