Summary: There is a growing interest in dissolved gallium (Ga) in natural waters for tracking water masses, but current analytical methods are time-consuming and labor-intensive. In this study, an automated isotope dilution method was developed to determine Ga in seawater using commercially available equipment. The method addressed challenges such as sample volume and pre-concentration, instrumental interferences, sample carryover, sample recovery variability, and improved detection limits, accuracy, and precision. The new automated method showed comparable Ga concentrations to traditional methods but with greater precision and a lower detection limit.

Summary: To analyze trace evidence at crime scenes, non-destructive or low-sample analysis techniques are preferred. One such technique is solid sampling ETV-ICPOES, which requires only a small amount of sample. This article discusses the capabilities of ETV-ICPOES in forensic analysis and presents various methods for analyzing physical evidence. Internal standardization and multivariate analysis are used to compensate for sample loading effects and enable quantification and discrimination of evidence. The article also explores future perspectives for utilizing ETV-ICPOES in forensic settings.

Summary: Laser ablation inductively coupled plasma mass spectrometry is a powerful technique for trace element analysis of solid samples, but its full quantitative capability is limited by the complex relationships between various factors. Altering laser ablation conditions can effectively change the physicochemical properties of LA-generated particles and improve the understanding of their impact on corresponding ICPMS signals. This multidimensional particle characterization approach can comprehensively study LA-generated particles and their effects on ICPMS signals, with potential for extension to other samples and laser wavelengths.

Summary: In this work, a portable analytical system based on point discharge chemical vapor generation atomic emission spectrometry (PD-CVG-AES) coupling with gold filament enrichment was designed. The highly sensitive analysis of Hg2+ indirectly realized the detection of ascorbic acid (AA). The measurement is based on the fact that Ag+ can decrease the concentration of Hg2+ by forming Ag-Hg amalgam in the presence of the reductant SnCl2, while AA can pre-reduce Ag+ to Ag0, leading to the generation of silver nanoparticles (Ag NPs). The developed novel analytical strategy broadens the application of microplasma-based AES and offers a higher level of sensitivity compared to current AA detection techniques.

Summary: The study developed a split aptamer-based sandwich-type ratiometric biosensor for the detection of 17 beta-estradiol (E2) using photoelectrochemical and electrochemical assays. The biosensor utilized split aptamer fragments to recognize E2 and trigger a hybridization chain reaction, resulting in the production of double-stranded DNA labeled with CdTe quantum dots. This DNA complex was able to sensitize CdTe quantum dots and generate response signals for E2 detection. The developed biosensor demonstrated high sensitivity and accuracy with two linear ranges and low detection limits.
