Preliminary analysis of latent fingerprints recovered from underneath bloodstains using matrix-assisted laser desorption/ionization fourier-transform ion cyclotron resonance mass spectrometry imaging (MALDI FT-ICR MSI)

Analysis of fingermark constituents: a systematic review of quantitative studies

“…The 19 studies included in the review were conducted between 1995 and 2021 and were from seven different countries (Table 2): Australia (Fritz et al 2013;Frick et al 2015;Dorakumbura et al 2018); Canada (Yeh et al 2020); Switzerland (Girod et al 2015(Girod et al , 2012; The Netherlands (Helmond et al 2017;Helmond et al 2019); United Kingdom (Bramble 2015;Ricci et al 2007a;Archer et al 2005;Croxton et al 2006Croxton et al , 2010Ferguson et al 2012;Wolstenholme et al 2009); USA (Asano et al 2002;Williams et al 2004); Spain/UK (Girod et al 2012). All of the aforementioned studies evaluated amino acids and/or lipids in latent fingermarks; however, they differed in the analytical technique use, number of donors and donors' characteristics (number, age, gender, and health/lifestyle factors).…”

“…This was followed by FTIR that was used in five studies (Fritz et al 2013;Girod et al 2015;Williams et al 2004;Dorakumbura et al 2018;Ricci et al 2007b). Each of LC-MS Helmond et al 2017;Helmond et al 2019) and MALDI-MS (Yeh et al 2020;Ferguson et al 2012;Wolstenholme et al 2009) was used in three studies. On the other hand, each of CE-MS (Atherton et al 2012), Raman spectroscopy (Dorakumbura et al 2018) and TLC (Bramble 2015) was used by one study only.…”

Forensic proteomics

“…The nature of fingermarks allows MALDI mass spectrometry to be conducted in a twodimensions resulting in images of multiple masses [295,304,316,[319][320][321]. This is a powerful approach to identification of relevant compounds in a fingermark, providing information about an individual's biology, metabolome and chemical exposure [295].…”

“…This is a powerful approach to identification of relevant compounds in a fingermark, providing information about an individual's biology, metabolome and chemical exposure [295]. This analysis also maintains and potentially enhances digital information in the latent print, resolve overlapping proteins, detect fingermarks below bloodstains [319], and can be adopted for proteomics [313,314,[322][323][324]. Proteomics has been used to identify body fluids in fingermarks, such as vaginal fluid or blood [162,314,315].…”

subMALDI: an open framework R package for processing irregularly-spaced mass spectrometry data

“…subMALDI was designed for use by researchers who wish to organize, process, and analyze single spectra data, particularly MS data, while still being able to access their raw data at various points throughout the process. It has been utilized in a scientific article in the Journal of Forensic Chemistry (Yeh et al, 2020) and in our laboratory for analysis of MALDI-MS and electrospray-ionization (ESI) MS data. The open framework format and data structures of subMALDI create a more transparent pipeline for processing of MS data, where users can easily access their raw data and better understand the processing algorithms that are being executed on their data sets.…”
