“…X-ray photoelectron spectroscopy (XPS) was used to measure the elemental composition of Fe 3 O 4 -GO, Fe 3 O 4 -GO-AuNPs and Fe 3 O 4 -GO-AuNPs-DNA TET. As shown in Figure S1a, the peak at 284.48 eV belongs to C 1s and the peaks at 711.23 and 724.63 eV belong to Fe 2p 3/2 and Fe 2p 1/2 respectively, suggesting the successful binding of GO and Fe 3 O 4 particles. The two peaks at 87.78 and 84.03 eV in Figures S1b and Figure (d) correspond to Au 4f 5/2 and Au 4f 7/2 , indicating that the gold nanoparticles were successfully modified on Fe 3 O 4 -GO.…”

In proteomics research, with advantages including short digestion times and reusable applications, immobilized enzyme reactors (IMERs) have been paid increasing attention. However, traditional IMERs ignore the reasonable spatial arrangement of trypsin on the supporting matrixes, resulting in the partial overlapping of the active domain on trypsin and reducing digesting efficiency. In this work, a DNA tetrahedron (DNA TET)-based IMER Fe 3 O 4 -GO-AuNPs-DNA TET-Trypsin was designed and prepared. The distance between vertices of DNA TETs effectively controls the distribution of trypsin on the nanomaterials; thus, highly efficient protein digestion and accurate quantitative results can be achieved. Compared to the in-solution digestion (12−16 h), the sequence coverage of bovine serum albumin was up to 91% after a 2-min digestion by the new IMER. In addition, 3328 proteins and 18,488 peptides can be identified from HeLa cell protein extract after a 20-min digestion. For the first time, human growth hormone reference material was rapidly and accurately quantified after a 4-h digestion by IMER. Therefore, this new IMER has great application potential in proteomics research and SI traceable quantification.

“…These results explicate that Gram-negative bacterium can be easily and fastly eliminated than Gram-positive ones. This is attributed to the structure of the Gram-negative cell wall, which consists of a thin layer of peptidoglycan (El Nahrawy et al 2019 ; Sun et al 2021 ). The interaction between SBPTE and the cell wall promotes its destruction, making the outflow of intracellular substances, leading to the death of bacteria (El Nahrawy et al 2019 ; Sun et al 2021 ).…”

Water decontamination from toxic dyes and pathogenic microorganisms is critical for life on Earth. Herein, we report the synthesis of sulfone biscompound containing 1,2,3-triazole moiety and evaluation of its dye decolorization and biocidal and disinfection efficiencies. The decolorization efficiency was tested under different experimental conditions, while the biocidal action was examined against various types of waterborne pathogens, and the disinfection of some pathogenic microbes was executed in artificially contaminated water. The findindgs illustrated that the solution initial pH (pHi) affected the decolorization efficiency significantly. About complete removal of 10 mg/L malachite green (MG) dye was achieved after 10 min using 3 g/L of the sulfone biscompound at pHi 6. The pseudo-second-order equation suited the adsorption kinetics accurately, while the equilibrium data was suited by Langmuir isotherm model. Electrostatic, n–π, and π–π interactions brought about the adsorption of MG onto the sulfone biscompound. The biocidal results indicated that the sulfone biscompound had a powerful antibacterial potential against the tested bacterial species. Likewise, the distinction trail revealed that after 70–90 min of direct contact with an effective dose, the tested pathogens could be completely eliminated (6-log reduction). Overall, the newly synthesized sulfone biscompound can efficiently remove cationic dyes and disinfect contaminated water.

Osteomyelitis is a type of bone infection caused by bacteria, with Staphylococcus sepsis being responsible for most cases. Osteomyelitis treatment generally requires a multifaceted approach that may include intervention of surgery and administration of antibacterial agents, where several materials have been utilized as delivery vehicles for antibiotics and other antibacterial materials. Hydrogel has become a popular candidate for osteomyelitis treatment due to its biocompatibility, water-containing porous structure, and adaptable physicochemical properties. In this review, we discuss several hydrogel-based strategies for osteomyelitis treatment and categorized them based on the encapsulated cargos (i.e., antibiotics, silver nanoparticles, protein and bacteriophage, and reactive oxygen species (ROS) generator). Several representative examples of osteomyelitis treatment using hydrogels are described here, focusing on their design, preparation, properties, and outcomes. We also provide our perspectives on the remaining concerns regarding fabricating advanced hydrogels for osteomyelitis treatment. This review will be valuable to the hydrogel community and inspire researchers to develop next-generation hydrogels for specific and practical clinical applications in osteomyelitis.
