Summary: The proposed automated method for extracting latent fingerprints and correcting surface curvature distortions is contactless, rapid, automatic, and chemical-free, and can obtain high quality fingerprint images even from difficult curved surfaces like glass lightbulbs and chrome water taps. The contactless nature of this method preserves the prints for DNA analysis and significantly improves fingerprint matching scores.

Summary: Four fluorescent low molecular weight gelators based on benzoxazole or benzothiazole functionalized pyrimidine were designed and synthesized, which could form stable supramolecular gels in an alcohol/water mixture. The gel formation was driven by hydrogen bonding, van der Waals forces, and weak interaction. The gel collapsed under UV light due to the [2 + 2]-cycloaddition reaction, and the fluorescent of the xerogel film could be quenched by volatile acids while enhanced in the solution after acid addition. The nano-fiber assembled via gel formation could be used for fluorescent imaging of latent fingerprints.

Summary: Vibrational spectroscopy techniques, including Raman and FTIR, are widely used in various fields. In this paper, a novel bimodal spectroscopy system that can simultaneously measure Raman and infrared spectra without interference is presented. The system demonstrates high sensitivity, precision, and resolution, and provides excellent calibration curves. The ability to obtain optically sectioned Raman signals is a unique feature of this system.

Summary: This study proposed a new method to quantify the developed contrast of latent fingerprints using fluorescent nanoparticles, with the developed contrast defined as the product of the chroma index and the common logarithm of the intensity index. The method was validated using different types of fluorescent nanoparticles on various substrates, showing that the developed contrast quantified by this method effectively reflected the true contrast. This work opens up a new avenue for quantifying and enhancing the developed contrast in latent fingerprint development.

Summary: This study investigated the metabolomic changes in coffee beans caused by the application of bioregulators using statistical mixture design and multivariate analysis. The results showed that ethanol and ethanol/dichloromethane were the most discriminating solvents. Gibberellin had the greatest differentiation compared to other bioregulators and may influence phenolic compounds. Additionally, berries harvested at different strata showed differences in metabolites.

Summary: Flavonoids are secondary metabolites commonly found in plants, known for their antioxidant properties, involvement in plant defense mechanisms, and responsibility for the pigmentation of fruits and flower petals. Consumption of foods rich in flavonoids brings various health benefits such as blood pressure regulation, anti-aging effects, and anti-cancer properties. Infrared and Raman spectroscopy are effective methods for quickly and accurately determining the presence of flavonoid compounds in test samples. These methods have been successfully applied in the food and pharmaceutical industries. The spectroscopic spectra of different flavonoid subgroups (flavones, isoflavones, flavanones, flavonols, and anthocyanins) are compared and described in this review.

Summary: Using amino-functionalized poly(p-phenylenevinylene) nanoparticles (PPV-brPEI NPs) as the developing reagent, a new strategy for efficient fingerprint development was proposed. The developed fingerprints showed high sensitivity and effectiveness for aged, contaminated, and moldy fingerprints, and could tolerate humidity and alcohol environment. The mechanism investigation revealed that the interaction between PPV-brPEI NPs and sebum ingredients contributed to the development of latent sebaceous fingerprints (LSFPs), while the interaction between PPV-brPEI NPs and proteins in blood contributed to the development of latent blood fingerprints (LBFPs).

Summary: In many developing countries, infants suffer and die from preventable diseases and malnutrition due to the lack of official identification documentation. Infant-Prints is proposed as a low-cost fingerprint recognition system for infants, which can accurately track their vaccination and nutritional supplement status, potentially preventing unnecessary suffering and premature death.

Summary: In this study, a novel SERS probe was developed using nucleic acid-peptide conjugates for high-specific profiling of abnormal protein levels in cancer patients. The probe showed rapid, simple, and multisignal detection capabilities. The effect of low-temperature storage time on blood samples was also analyzed, and it was found that plasma samples stored at 4°C for more than 2 days could generate false negative results due to TB hydrolysis, highlighting the importance of clinical sample analysis. This nucleic acid-peptide conjugate provides new ideas for future SERS sensing strategies.

Summary: This study investigated L-cysteine S-sulfate, Cys-SSO3H, and their derivatives through electrospray ionization and negative ion photoelectron spectroscopy. The results showed that the deprotonated anion [cysS-SO3](-) was stabilized by three intramolecular hydrogen bonds, with the amino group acting as both acceptor and donor. The theoretical predictions and experimental findings also suggested the existence of a competing isomer, characterized by an O-HN-HS chain-type binding motif. The infrared spectra provided a way to distinguish different isomers. This research lays the foundation for understanding the transformation and structure-reactivity correlation of Cys-SSO3H in biological settings.
