“…The results demonstrate that the fluorescent powder dusting technique is highly effective in enhancing the visibility of latent fingerprints. The even layer of fluorescent powder applied to the surfaces of various photo papers allowed for clear and distinct fingerprint visualization [7,9,12]. This indicates that the technique holds great potential for forensic investigations as a reliable method for detecting latent fingerprints.…”

“…Different fluorescent powders exhibit varying degrees of fluorescence under different light wavelengths, making it crucial to select the appropriate powder color that maximizes the contrast with the background surface. Additionally, the choice of light source, such as ultraviolet (UV) or various LED colors, can significantly impact the visibility and clarity of the detected fingerprints [9].…”

This study examined the use of fluorescent powder in detecting latent fingerprints through the dusting method. Five colors of fluorescent powder (orange, green, blue, green-yellow, and red) were applied to photo papers of six colors (green, red, blue, yellow, white, and black). The fluorescence of latent fingerprints was detected using various light sources including UV LED, blue LED, green LED, red LED, warm white, and cold white. The spectra of the light source and the fluorescence intensity of the dusting powder were analyzed to determine their influence on the appearance of latent fingerprints. The fingerprint images were analyzed by counting the number of important points that are more than 7 points, which indicates visible fingerprints. The results showed that the fluorescence of the powder, background, and light source affected the appearance of the fingerprints. When the color of the fluorescent powder matched the color of the light source, the fingerprints were clearly visible. However, if the background color matched the light source, the fingerprints were not visible. When fluorescent powder was dusted on a dark or non-fluorescent background, fingerprints were visible under all light sources. This study suggests that selecting the appropriate color of fluorescent powder and background is crucial for the detection of latent fingerprints using the dusting method.

“…Thus, fluorophores with AIE properties have been actively developed for organelle imaging applications such as mitochondria, 34 lysosomes, 35,36 nuclei, 37,38 and LDs. 23,39,40 In addition, widely used AIE luminogens (AIEgens) such as triphenylamine (TPA) and tetraphenylethylene (TPE) groups can serve as excellent electron donors for push−pull interactions, maximizing signal enhancement. These fluorophores generally exhibit not only high selectivity and low background signals, but also demonstrate red-shifted emission, which is useful for imaging live cells and tissues.…”

Lipids are essential for various cellular functions, including energy storage, membrane flexibility, and signaling molecule production. Maintaining proper lipid levels is important to prevent health problems such as cancer, neurodegenerative disorders, cardiovascular diseases, obesity, and diabetes. Monitoring cellular lipid droplets (LDs) in real-time with high resolution can provide insights into LD-related pathways and diseases owing to the dynamic nature of LDs. Fluorescence-based imaging is widely used for tracking LDs in live cells and animal models. However, the current fluorophores have limitations such as poor photostability and high background staining. Herein, we developed a novel fluorogenic probe based on a push−pull interaction combined with aggregation-induced emission enhancement (AIEE) for dynamic imaging of LDs. Probe 1 exhibits favorable membrane permeability and spectroscopic characteristics, allowing specific imaging of cellular LDs and time-lapse imaging of LD accumulation. This probe can also be used to examine LDs in fruit fly tissues in various metabolic states, serving as a highly versatile and specific tool for dynamic LD imaging in cellular and tissue environments.
