Summary: This study investigated four different types of deep eutectic solvents for bamboo waste fractionation, revealing that acidic solvents were more effective in biomass delignification while alkaline solvents showed better polysaccharide retention. Additionally, glycerol-K2CO3 LNPs had smaller sphere size, and acidic DESs LNPs exhibited higher thermal stability. Additionally, MEA-ChCl could introduce amine groups onto lignin hydroxyl, providing insightful information for selective lignocellulosic waste fractionation techniques.

Summary: In order to use deep eutectic solvents (DESs) as an alternative to traditional organic solvents, it is necessary to understand their physicochemical properties. This study synthesized several novel DESs and thoroughly characterized their properties such as thermal stability, viscosity, surface tension, refractive index, density, speed of sound, and conductivity. The effects of temperature, type of hydrogen bond donors, and alkyl chain length on the properties were examined and discussed. The relationship between molar conductivity and dynamic viscosity was established to evaluate the ionicity of the synthesized DESs. Insights into structure-property correlations were also discussed.

Summary: Deep eutectic solvents (DESs), a new class of environmentally friendly solvents, have gained attention for their ability to extract and separate targeted analytes from complex samples. DESs are liquid at room temperature and possess excellent thermal and electrical stability. They are sustainable solvents with non-volatile, non-flammable, chemically stable, and biocompatible properties. DESs can be tailored to meet specific needs due to their tunable physicochemical properties. This review summarizes the use of DESs-based adsorbent materials and highlights their unique properties in extraction and separation applications.

Summary: Anthocyanins are extracted using alternative solvents such as ionic liquids, deep eutectic solvents, and natural deep eutectic solvents, which are more environmentally friendly and efficient compared to conventional solvents. Acid-based deep eutectic solvents with 20-30% water content showed the highest anthocyanin extraction yield. Ultrasonic-assisted extraction was the most common and efficient method, and DES-based extracts exhibited the highest stability and antioxidant activity. Fruits and their by-products are the most commonly used samples, while cereal and legumes are less explored.

Summary: In this study, three deep eutectic mixtures (DES) were used as mediums to synthesize glucose laurate and glucose acetate. Lipases from Aspergillus oryzae (LAO), Candida rugosa (LCR), and porcine pancreas (LPP) were employed as catalysts. The results showed that DES did not deactivate the lipases when used as medium. For transesterification reactions, combining LAO or LCR with DES 3 resulted in efficient production of glucose laurate, while LPP performed best in DES 2 for glucose acetate synthesis. Substituting vinyl laurate with vinyl acetate led to different behaviors, with LCR and LPP showing better catalytic activity in DES 1 for glucose acetate production. LAO had lower activity, with only around 40% product yield in DES 3. These findings highlight the potential of biocatalysis combined with greener solvents for the synthesis of differentiated sugar fatty acid esters.

Summary: Deep eutectic solvents (DESs) are composed of a hydrogen bond donor and acceptor, and the interactions between them significantly lower the melting point of the mixture. Despite having eutectic melting temperatures above room temperature, all investigated DESs were able to appear liquid at room temperature under ambient conditions due to low RH0.

Summary: The photophysics and torsional dynamics of thiazole orange (TO) in two deep eutectic solvents (DESs) were studied, with the fluorescence quantum yield and lifetime of TO decreasing at higher temperatures due to thermal deactivation. The molecular rotor nature of TO in DESs may contribute to the decrease in fluorescence quantum yield at higher temperatures. The free volume idea in these solvents accurately predicted the solvent viscosity-temperature behavior and probe torsional dynamics.

Summary: Photodynamic therapy (PDT) is a promising local treatment modality in cancer therapy, but its therapeutic efficacy is restricted by ineffective delivery of photosensitizers and tumor hypoxia. In this study, a phototactic Chlorella-based near-infrared (NIR) driven green affording-oxygen microrobot system was developed for enhanced PDT. The system exhibited desirable phototaxis and continuous oxygen generation, leading to the inhibition of tumor growth in mice. This study demonstrates the potential of using a light-driven green affording-oxygen microrobot to enhance photodynamic therapy.
