AB  - The forensic scenario, on which the round robin study was based, simulated a suspected intentional manipulation
of a real estate rental agreement consisting of a total of three pages. The aims of this study were to (i) establish
the amount and reliability of information extractable from a single type of evidence and to (ii) provide suggestions
on the most suitable combination of compatible techniques for a multi-modal imaging approach to
forgery detection. To address these aims, seventeen laboratories from sixteen countries were invited to answer
the following tasks questions: (i) which printing technique was used? (ii) were the three pages printed with the
same printer? (iii) were the three pages made from the same paper? (iv) were the three pages originally stapled?
(v) were the headings and signatures written with the same ink? and (vi) were headings and signatures of the
same age on all pages? The methods used were classified into the following categories: Optical spectroscopy,
including multispectral imaging, smartphone mapping, UV-luminescence and LIBS; Infrared spectroscopy,
including Raman and FTIR (micro-)spectroscopy; X-ray spectroscopy, including SEM-EDX, PIXE and XPS; Mass
spectrometry, including ICPMS, SIMS, MALDI and LDIMS; Electrostatic imaging, as well as non-imaging
methods, such as non-multimodal visual inspection, (micro-)spectroscopy, physical testing and thin layer
chromatography. The performance of the techniques was evaluated as the proportion of discriminated sample
pairs to all possible sample pairs. For the undiscriminated sample pairs, a distinction was made between undecidability
and false positive claims. It was found that none of the methods used were able to solve all tasks
completely and/or correctly and that certain methods were a priori judged unsuitable by the laboratories for
some tasks. Correct results were generally achieved for the discrimination of printer toners, whereas incorrect
results in the discrimination of inks. For the discrimination of paper, solid state analytical methods proved to be
superior to mass spectrometric methods. None of the participating laboratories deemed addressing ink age
feasible. It was concluded that correct forensic statements can only be achieved by the complementary application
of different methods and that the classical approach of round robin studies to send standardised subsamples
to the participants is not feasible for a true multimodal approach if the techniques are not available at
one location.

AB  - Fingerprints analysis has been used as a powerful and reliable tool for individual identification in forensic science for more than a century. Some traditional techniques used toxic agents, so the application of fluorescent biocompatible materials, such as N-Carbon Dots (N-CDs), can be used as-received and it is non-toxic, as opposed to a lead carbonate powder routinely used by the police. N-CDs have recently gained the attention of scientists because of their stable luminescence, hydrophilicity, chemical inertness, photo-bleaching resistance, easiness of their functionalization, and low cost. In this research, N-CDs were obtained in a simple step process using the hydrothermal treatment of polyvinylpyrrolidone (PVP), as an N source, and further used for the detection of fingerprints through fluorescent imaging. A brightness emission at 495 nm of N-CDs was related to their structural and chemical properties. Detailed surface characterizations with ss-NMR, XPS, and fluorescence spectroscopies, suggested that the negative charge of the functional groups promoted electrostatic interactions between the charged N-CDs surface functional groups (amine, carboxylic, and amide) and the secretion components present in the thin layer of fluid left on the surface upon its direct contact with human fingers. Based on biometric identification, the obtained results were validated by the scientific protocol of the Police Automated Fingerprint Identification System (AFIS).
