Summary: This paper presents the development of a novel trilinolein biosensor using lipase and lipoxygenase immobilized on a cobalt phthalocyanine screen-printed carbon electrode. The biosensor demonstrates selective response to polyunsaturated fatty acid (PUFA) triglycerides, distinguishing them from monounsaturated (MUFA) and saturated fatty acid (SFA) triglycerides. The biosensor shows a linear range of 0.2-10 μM and a detection limit of 45.5 nM. It has been successfully applied to measure trilinolein in a pharmaceutical food supplement with a recovery rate of 86% and a coefficient of variation of 5.05%. This simple and cost-effective LOX-lipase biosensor shows great potential for various applications, including food and clinical samples.

Summary: Heavy metal pollution is a global environmental issue. In this study, a screen printed electrode modified with bismuth powder (Bi-SPE) was prepared for the detection of Cd2+. The Bi-SPE exhibited a linear detection range of 5-50 μg/L and a detection limit of 4.80 μg/L for Cd2+. Compared to the bare screen printed electrode, Bi-SPE showed better detection performance by providing more active sites for heavy metal ion predeposition. The advantage of Bi-SPE is its ability to detect heavy metal ions without the addition of bismuth ions in the solution, enabling in-situ detection. The prepared Bi-SPE holds great potential for the detection of heavy metal ions in real water samples.

Summary: This study investigated the electrochemical synthesis of Prussian blue (PB) nanocrystals on a screen-printed carbon electrode modified with magnetite nanoparticles. The characteristics and properties of acids in the mixture solution were found to highly affect the voltammetric responses of the generated PB nanocrystals. Interestingly, surface magnetite nanoparticles were occluded within electrogenerated PB nanocubes in the presence of glyphosate as an organic acid.

Summary: Enzymes play a crucial role as biological catalysts in accelerating biochemical reactions in living organisms. This study proposes a convenient method for monitoring enzymatic catalytic processes using native top-down mass spectrometry. By exploring the heterogeneity of the chymotrypsin sample and using tandem mass spectrometry, the researchers were able to monitor covalent and noncovalent enzymatic complexes, substrates, and products during catalysis. The results demonstrate that this method has the potential to be a promising tool for characterizing biocatalysts.

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.
