Abstract
Latent fingerprints, as one of the most frequently encountered traces in crime scene investigation and also one of the largest sources of forensic evidence, can play a critical role in determining the identity of a person who may be involved in a crime. Due to the invisible characteristic of latent fingerprints, exploring efficient techniques to visualize them (especially the ones resided on metallic surfaces) while retain the biological and chemical information (e.g., touch DNA) has become a multidisciplinary research focus. Herein we reported a new and highly sensitive electrochemical interfacial strategy of simultaneously developing and enhancing latent fingerprints on stainless steel based on synchronous electrodeposition and electrochromism of manganese oxides in a neutral aqueous electrolyte. By utilizing a specially designed device for electrochemical testing and image capture, a series of electrochemical measurements, physical characterization and image analysis have been applied to evaluate the feasibility, development accuracy and enhancement efficacy of the proposed electrochemical system. The qualitative and quantitative analysis on the in situ and ex situ fingerprint images indicates that the three levels of fingerprint features can be precisely developed and effectively enhanced. Forensic DNA typing has also been performed to reveal actual impact of the proposed electrochemical system on subsequent analysis of touch DNA in fingerprint residues. The ratio of detected loci after electrochemical treatment reaches up to 98.5 %, showing non-destructive nature of this fingerprint development and enhancement technique.

Abstract
Powder dusting method is the most widely used approach due to its low cost, simplicity, minimal instrument dependence, and extensive applicability for developing latent fingerprints (LFPs). Herein, a novel optical and electrochemical dual-mode method for high-resolution LFP enhancement has been explored based on size-tunable polydopamine (PDA) nanoparticles (NPs) and scanning electrochemical microscopy (SECM). Dark PDAs rich in functional groups and negative charges can combine with the residues of LFPs on various surfaces with high sensitivity and selectivity to realize high-resolution visual fingerprint physical patterns on various porous and nonporous substrates with light color. However, optical visualization is not feasible for LFPs on dark or multicolored surfaces. Fortunately, based on the differences in electrochemical reactivity between ridges and furrows caused by the conductivity and reducibility of PDA powders, SECM can serve as a powerful supplement to optical methods to effectively overcome background color interference and distinctly display fingerprint patterns. Intriguingly, it is noteworthy that the binding amount and particle size of PDA powder significantly affected the optical and electrochemical visualization of LFPs: more powder binding amounts provided darker ridges in optical, and more surface reaction sites (larger powder binding mass at the same particle size or smaller particle size at the same mass) provided higher currents of ridges in electrochemical imaging. It demonstrates that the PDA powder as a dual-mode developer for LFPs offers a promising method for individual identification in forensics.

Abstract
Fingerprints have long been the gold standard for personal identification in forensic science. However, realizing the high-resolution enhancement of eccrine LFPs is difficult using the traditional methods and the label-free detection of fingerprint residue information is also challenging. Herein, we propose two enhancement strategies for LFPs on PVDF membrane (LFPs/PVDF) using blue-black ink staining and scanning electrochemical microscopy (SECM). The blue-black ink staining method was used for the first time to develop three types (sebaceous, natural and eccrine) of LFPs/PVDF based on the difference in wettability between the fingerprint residues and PVDF membrane. The enhanced fingerprints clearly displayed levels 1-3 features with high contrast and low background interference. Furthermore, we achieved chemical imaging of the LFP/PVDF samples, where their possible visualization mechanisms were ascribed to the electrochemical reactivity of squalene and difference in wettability between the LFP and PVDF membrane, which was first proposed and investigated by SECM imaging and water contact angle (WCA) measurements, respectively. Significantly, SECM imaging not only provided fingerprint patterns without any labelling but also revealed the spatial distribution information of squalene in LFPs simultaneously. In addition, it was also demonstrated that LFPs deposited on various surfaces were first successfully transferred to the PVDF membrane, and then further developed with both methods, making them general for personal identity-related applications. Taken together, the blue-black ink staining method can easily and quickly obtain level 3 features of LFPs/PVDF and the SECM approach can non-invasively image the topography and chemical information of LFPs/PVDF, and thus they can be potentially selected according to various requirements in forensic scenarios.

Extended non-destructive testing for inline quality control of cleaning and pre-treatment processes in adhesive bonding of polymer blends. SN APPLIED SCIENCES 2023.

Abstract
AbstractThis investigation aims to demonstrate relevant pitfalls of exemplary surface contaminations on polymer blends with respect to quality assurance (QA) of adhesive joints, and highlights approaches of Extended Non-Destructive Testing (ENDT) for tackling the challenges inline during manufacture or repair processes. Greasy fingerprints were intentionally applied on surfaces of different acrylonitrile butadiene styrene (ABS) substrates before joining them with a two component (2C) polyurethane (PU) adhesive. Even when a required cleaning process was omitted before performing a pre-treatment with atmospheric-pressure plasma (APP), measured initial strengths of unaged joints did not reveal significant differences, if compared to joints produced following the qualified bonding process, which comprises a wipe-off wet cleaning before the pre-treatment step. However, after accelerated ageing mimicking the application conditions for joints, resulting strengths were more than 30% lower than for joints produced with the qualified bonding process. Thus, applying post-process random inspection of as-manufactured joints based on destructive testing, and merely evaluating initial joint strengths is not sufficient for assuring the reliability of such manufactured joints. Rather, it is recommended to encompass the intended or specified use within the formulation of the quality requirements. Introducing in-process ENDT procedures, and exemplarily monitoring the substrate surfaces with an Aerosol Wetting Test (AWT), is shown to identify latent fingerprints and to ensure a rapid and documented way to validate adherend surface quality before the application of the adhesive.Article Highlights
Surface quality assurance leads the way for process management decisions to safeguard relevant adherend properties before applying adhesive.
Using an Aerosol Wetting Test for plastic adherends allows for identifying latent fingerprints that would impair joint strength.
Extended Non-Destructive Testing facilitates embracing potential in-process contaminations when scheduling cleaning processes for adherends.
