“…This method is particularly useful in visualizing LFPs on metal surfaces, e.g., stainless steel [48], that are often found in felony cases. Recently, Tan et al [49] demonstrated the visualization of oily LFPs and in situ detection of TNT in fingerprints by using an ECL-based image-contrast technology on the surface of porous silicon. Unlike the ECL based on molecular luminescence, this technology does not require a co-reactant.…”

“…Traditional ECL luminophores include metal complexes [36], luminol [37], silicon nanoparticles [38], and quantum dots [39]. Carbon materials, such as graphite-like carbon nitride, carbon nanodots, graphene as well as its composites, have also been studied as ECL emitters [40][41][42][43][44][45].…”

Due to strong photoluminescence, extraordinary photostability, excellent biocompatibility, and good water-solubility, metal nanoclusters have attracted enormous attention since discovered. They are found to be novel fluorescence labels for biological applications and environmental monitoring. Recently the chemiluminescence (CL) or electrochemiluminescence (ECL) of metal nanoclusters has received increasing attention. This review covers recent vibrant developments in this field of the past 5 years, and highlights different functions of metal nanoclusters in various CL and ECL systems, such as luminophores, catalysts, and quenchers. Latest synthetic methods of metal nanoclusters used in CL or ECL are also summarized. Furthermore, we discuss some perspectives and critical challenges of this field in the near future. nanoclusters, chemiluminescence, electrochemiluminescence, fluorescence, sensors Citation:Han S, Zhang Z, Li S, Qi L, Xu G.

“…Recently, new techniques such as electrochemiluminescence and nanotechnology have been applied toward the enhanced development of latent fingermarks [6–11]. In particular, the use of fluorescent nanoparticles (NPs), such as quantum dots (QDs), for the development of latent fingermarks has attracted significant research interest in forensic science [12–18]; this is because of their unique physical and chemical properties such as small particle size, large surface area, good photochemical stability, and high fluorescent intensity.…”

The most commonly found fingermarks at crime scenes are latent and, thus, an efficient method for detecting latent fingermarks is very important. However, traditional developing techniques have drawbacks such as low detection sensitivity, high background interference, complicated operation, and high toxicity. To tackle this challenge, we employed fluorescent NaYF4:Yb,Er upconversion nanoparticles (UCNPs), which can fluoresce visible light when excited by 980 nm human-safe near-infrared light, to stain the latent fingermarks on various substrate surfaces. The UCNPs were successfully used as a novel fluorescent label for the detection of latent fingermarks with high sensitivity, low background, high efficiency, and low toxicity on various substrates including non-infiltrating materials (glass, marble, aluminum alloy sheets, stainless steel sheets, aluminum foils, and plastic cards), semi-infiltrating materials (floor leathers, ceramic tiles, wood floor, and painted wood), and infiltrating materials such as various types of papers. This work shows that UCNPs are a versatile fluorescent label for the facile detection of fingermarks on virtually any material, enabling their practical applications in forensic sciences.
