I am happy to share our recent publication. In this work, we report the synthesis of palm trunk–like ZnO hierarchical nanostructures via a hydrothermal method. These nanostructures were uniformly grown, vertically oriented, and possessed a palm trunk–like morphology. The designed biosensor with these hierarchical nanostructures demonstrated promising potential as a nanomaterial-based glucose biosensor.  https://lnkd.in/gzh7TcnS

Advancing Fluorescence Imaging with our Circular Dichroism instrument 🔬 Researchers introduce a novel strategy to enhance fluorescence imaging in biological processes by developing advanced fluorogenic probes targeting intracellular sites with high specificity. This method transforms polymethine compounds into efficient fluorogenic dyes through an intramolecular ring-closure approach. The resulting dyes exhibit emissions across the visible and near-infrared spectrum, offering versatility and compatibility with self-labelling proteins and small-molecule targeting ligands. These probes enable multicolour and fluorescence lifetime multiplexing imaging when combined with rhodamine-based dyes. The strategy promises bright, fluorogenic dyes emitting at more red-shifted wavelengths than existing rhodamine-based dyes, overcoming limitations of long syntheses and spectral range restrictions. ✨🔍 📖 Learn More: https://lnkd.in/ebwE-4YN Check out the Chirascan V100 used in this research: https://bit.ly/3uOqFbJ #FluorescenceImaging #FluorogenicProbes #Spectroscopy #CircularDichroism

Scientists from the #BiosensorsAndDevicesLab in ACS Biomaterials Science & Engineering are studying how the body reacties to implanted biomaterials focusing on macrophages. In their very first paper 🙌 they share how they introduce a magnetically actuated hydrogel (Madsurface) that can change its stifness back and forth. The study focused on exploring the potential of magnetic fields and MadSurfaces in dynamically modulating macrophage behavior in a programmable manner. The MadSurface approach advances our understanding of the interplay between magnetic field, cell microenvironment alterations, and macrophage behavior. 👇 You can read their article in the open access read below. This study a collaborative effort of Burcu Gumuscu (Sefunc), Ph.D.'s team including Lanhui Li and Els Alsema at the Department of Biomedical Engineering at TU/e and Nick Beijer's team at RIVM National Institute for Public Health and the Environment. #hydrogel #magnetic #biomaterials #macrophage

Source: Photochemistry and photobiology A new capping agent called dansyl-tagged xanthate ester (DX) was developed to synthesize fluorescent silver nanoparticles (AgNPs) with binding affinity towards serum albumin. The DX-capped AgNPs were characterized and showed specific photochemical properties. The AgNPs exhibited distinct absorption and fluorescence spectra, as well as a high quantum yield and positive zeta potential. The nanoparticles also demonstrated strong interaction with bovine serum albumin (BSA) and human serum albumin (HSA) through fluorescence resonance energy transfer (FRET). This study highlights the potential of using DX-capped AgNPs for biomedical applications.

Standardising the determination of nanoparticle size and concentration using nanoparticle tracking analysis: Hong Qiu at Chinese Academy of Sciences and collaborators implemented the "search-evaluate-test" approach to standardize NTA measurements by identifying crucial parameters. The number of particles per frame shows a linear correlation with sample concentration, with more accurate and reproducible results obtained when the concentration ranges between 1E8 and 1E9 particles per mL https://lnkd.in/e4d4bpch They also examined polystyrene, silica, and biological nanoparticles using NTA according to their standard operating procedures (SOPs), and compared their findings with orthogonal nanoparticle sizing techniques like transmission electron microscopy (TEM) and resistive pulse sensing (RPS). also authored by Youxi Tian, Dong Tian and peng xinsheng #extracellularvesicles #exosomes #NTA #nanoparticles #nanomedicine #viruses #Vesiculab

Biophotonics biophotonics is used to describe any technique dealing with the interaction between biological items and photons. This refers to emissions, detection, absorption, reflection, modification, and creation of radiation from biomolecular, cells, tissues, organisms, and biomaterials. In addition to the applications noted earlier – biophotonics is used in industries such as life science, medicine, agriculture, and environmental science.There is a difference between the use of light for therapy and surgery, where it serves the purpose of transferring energy, and its use for diagnostics. In the latter case, light is utilized to excite matter and provide information to the operator. Biophotonics is usually associated with the latter type of application.

[New publication] glad to share our newest publication "Data-driven optimization of the in silico design of ionic liquids as interfacial cell culture fluids" in the journal "Science and Technology of Advanced Materials. https://lnkd.in/gFdF8sKF In this paper, Using a data-driven approach, we were able to identify non-cytotoxic ammonium-type ionic liquids with a limited number of cytotoxicity tests. The Structure – cytotoxicity analysis indicated that the presence of multiple long alkyl branches was critical for low cytotoxicity. Using those ionic liquid, we successfully cultured human mesenchymal stem cells (hMSCs) at the trihexylethylammonium trifluoromethylsulfonylimide interface and repeated their use after solvent extraction and heat sterilization. #materialsinformatics #AI #ionicliquid #materialsscience #NIMS #stemcells

✨Visualizing Exosomes✨ #Exosomes, which are tiny, nanometric extracellular vesicles, are one of the most promising frontiers in biomedical research! Unlike cells and bacteria, which can be visualized with a common bright field microscope, exosomes are much smaller, about 1:100 the size of a cell and 1:10 the size of a bacterium. Therefore, verifying exosome quality following isolation can be quite challenging. At Smart Assays Biotechnologies Ltd., we isolate exosomes from cell-conditioned media using specialized Size Exclusion Chromatography (SEC) columns. This method was chosen due to its higher purity of the exosome fraction compared to the classical ultracentrifuge isolation technique. Following isolation, we utilize Nanoparticle Tracking Analysis (NTA), Dynamic light scattering (DLS), and Transmission Electron Microscopy (TEM) to characterize the exosome fraction. NTA provides quantitative analysis of the number of particles and their sizes and TEM images enable us to further assess particle size and morphology. The average diameter results from TEM closely matched our NTA and DLS measurements, and the observed morphology aligns with descriptions published in the literature. The illustration below visualizes the comparison of various biological structures. Ranging from the smallest, a virus, to the largest, an animal cell. It highlights the green-pseudo-colored TEM images of exosomes and microvesicles (MVs) obtained by Smart-Assays Biotechnologies. #exosomes #microvesicles #TEM #
