Summary: This study investigates the potential of using small amounts of ionic liquids to enhance ultrasound-assisted extraction of lipids content from green microalgae. The findings suggest that the addition of ILs improves ultrasonication by enhancing viscosity and reducing water surface tension, resulting in a more powerful acoustic cavitation process. Additionally, the yield of extracted lipids from green microalgae shows an incremental trend with increasing IL concentration.

Summary: This study discovered the important physiological functions of Ipomoea batatas polysaccharides (IBPs) and determined the optimal extraction conditions. The main chain of IBP-1A was found to primarily consist of specific sugar residues. In vivo experiments on older mice showed that polysaccharide significantly increased antioxidation-related enzymes and metabolites, effectively relieving oxidative stress injury and delaying aging. Thus, this research provides a new theoretical basis for the development of IBPs as antioxidant food.

Summary: In this work, we developed a new method for the preparation of Ti3C2 MXene (MXene-DES) with few layers and a high degree of hydroxylation. The method involved the use of a deep eutectic solvent (DES)-assisted electrochemical ultrasonic composite exfoliation, which is easy to scale up. The MXene-DES exhibited improved properties compared to MXene-N-2, including fewer layers, larger interlayer spacing, higher degree of hydroxylation, and stronger oxidation resistance. This strategy provides a simple, low-cost, and environmentally friendly approach to the scalable preparation and application of antioxidative high-quality MXene.

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.
