Summary: Surface-enhanced Raman spectroscopy (SERS) is a powerful technique used in various research fields. Semiconductor SERS substrates, as alternatives to plasmonic metal substrates, have attractive attributes. However, they can only enhance the signals of analytes chemically adsorbed on their surface. In this study, we demonstrate the detection of non-adsorbing analytes on ZnO nanoparticles by coating them with ZIF-8 shells, which significantly enhances their electromagnetic enhancing capability and enables the detection of a wider range of non-adsorbing analytes.

Summary: Treatment of hydrogen plasma on silicon nanowires, followed by coatings of nanocrystalline diamond and multilayer graphene, enables enhanced Raman signals with reduced fluorescent background. The graphene-coated nanowires show lower fluorescent background than diamond-coated ones, with a minimum detection limit of 10(7) mol/L and an enhancement factor exceeding 10(4). The stable Raman enhancement is attributed to hydrogen-terminated graphene and the nanowire structure, independent of graphene layers and maintaining stability after exposure to the atmosphere for a month.

Summary: In order to address the presence of fluoroquinolone antibiotics in aquatic environments, it is necessary to design a semiconductor photocatalyst with excellent photocatalytic efficiency. This study explored the performance of MnNb2O6/g-C3N4 composites in the photocatalytic degradation of ciprofloxacin and tetracycline-HCl antibiotics. The enhanced photocatalytic activity of MNO/g-CN was found to be due to the electron's shifting between the MNO and g-CN sheets, promoting the formation of photo-generated e(-)/h(+) pairs, indicating the existence of a low-waste, high-performance material for eradicating ciprofloxacin and tetracycline-HCl from wastewater.

Summary: This study investigates the use of MoS2 NS to convert ultrasound energy into localized electrical stimulation for neural activation. The results demonstrate that a single pulse of ultrasound can effectively stimulate cells surrounding MoS2 NS without causing cellular damage. The proportion of responsive cells is influenced by the acoustic pressure, number of ultrasound cycles, and concentration of MoS2 NS. This method shows high spatial precision and potential for selective modulation of targeted brain circuits.

Summary: This article introduces a new technique for the synthesis of colloidosomes using a microfluidic droplet device and partially miscible liquids. By dissolving liquids within droplets, hydrophilic nanoparticles can be close-packed at the liquid interface to form colloidosomes. This method also enables colloidosomes to be synthesized within a narrow range of sizes. The close-packing of nanoparticles is confirmed by modifying colloidosomes into signal-enhanced lateral flow assays, which demonstrates their potential application in bacterial detection platforms, drug encapsulation, and biosensing.

Summary: A ratiometric fluorescent probe based on o-phenylenediamine-derived carbonized polymer dots (o-PD CPDs) was developed for real-time intracellular detection of singlet oxygen (1O2). The o-PD CPDs can produce 1O2 and selectively quench the yellow fluorescence, allowing for the selective detection of 1O2 against other reactive oxygen species (ROS). The probe was successfully applied to monitor 1O2 level in the intracellular environment and detect 1O2 and other ROS species in an inflammatory neutrophil cell model.

Summary: Thermogalvanic gels show great promise in renewable energy sources due to their flexibility, stability, and functional diversity. However, their limited adaptability to low or high temperature environments hinders practical applications. In this study, an anhydrous thermogalvanic gel with exceptional temperature tolerance and anti-drying properties is developed using Fe3+/2+ as a redox pair. The gel maintains mechanical flexibility and electrical conductivity over a wide temperature range, thanks to the hydrogen bonds formed between the molecules. This research provides insights into creating flexible thermoelectric materials for energy recovery and self-powered wearable electronics.

Summary: We have developed multifunctional nanogels with antimicrobial, antioxidant, and anti-inflammatory properties, facilitating rapid wound healing. The nanogels, formed using quercetin and a carbonization process, possess excellent antioxidative and bacterial targeting properties. By incorporating copper sulfide nanoclusters, the nanogels show enhanced antimicrobial effects and can eradicate biofilms in diabetic mice wounds. The presence of the nanogels also regulates the expression of inflammatory and anti-inflammatory factors, promoting angiogenesis, epithelialization, and collagen synthesis for accelerated wound healing.

Summary: The process of wound healing is often obstructed by bacterial infection. To achieve effective wound recovery, it is necessary to develop innovative strategies to alleviate infection. In this study, a self-activated composite dressing was developed, consisting of piezoelectric and photothermal functional layers, to combat wound infection and provide the desired treatment. This dressing can generate reactive oxygen species (ROS) for antibacterial activity, and convert them into molecular oxygen (O2) to treat chronic hypoxia in infected wounds. Additionally, the dressing can enhance wound recovery through its photothermal activity.

The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
