The University of Alberta and National Research Council Canada / Conseil national de recherches Canada authors Robert Peters, Luis Gutierrez-Rivera, Steven Dew, and Maria Stepanova in their paper "Surface Enhanced Raman Spectroscopy Detection of Biomolecules Using #EBL Fabricated Nanostructured Substrates" fabricate and characterize conjugate nano-biological systems interfacing metallic nanostructures on solid supports with immobilized biomolecules. The fabrication of nanostructured substrates using #electron #beam #lithography, immobilization of biomolecules on the substrates, and their characterization utilizing surface-enhanced #Raman #spectroscopy (#SERS) are discussed. Three different designs of nano-biological systems are employed, including protein A, glucose binding protein, and a dopamine-binding #DNA aptamer. The binding of respective ligands, D-glucose and dopamine, is also included in the latter two cases. The three kinds of biomolecules are immobilized on nanostructured substrates by different methods, and the results of SERS imaging are reported. The capabilities of SERS to detect vibrational modes from surface-immobilized proteins, as well as to capture the protein-ligand and aptamer-ligand binding are demonstrated. The results also illustrate the influence of the surface nanostructure geometry, biomolecules immobilization strategy, the molecules' Raman activity, and the presence or absence of the ligand binding on the SERS spectra acquired.

Finally! After a long and rigorous review process, I am pleased to announce that our latest paper, "Molecular Strong Coupling and Cavity Finesse," has been published in JPCL. Our research demonstrates that the effectiveness of molecular strong coupling critically depends on cavity finesse. Previous reports on open cavities have noted changes in molecular absorption but have not conclusively shown effective chemical control. Our study explores photoluminescence in open, half, and full cavities to gain deeper insights into cavity-free strong coupling. This research identifies an additional requirement for effective molecular strong coupling, underscoring the essential role of cavity finesse in controlling chemistry.

Exciting new review about the innovative use of laser techniques in developing and functionalizing biomimetic surfaces! 🐞 🌿   📜 Advanced Laser Techniques for the Development of Nature-Inspired Biomimetic Surfaces Applied in the Medical Field   🔑 #biomimetic #materials; #surface #functionalization; #lasertechniques   Read and download for FREE 👉 https://lnkd.in/ddTfuSD8 🎓 By Anita Ioana Visan and Gianina Florentina Popescu-Pelin   🏛 National Institute for Lasers, Plasma and Radiation This review focuses on the innovative use of laser techniques in developing and functionalizing biomimetic surfaces, emphasizing their potential applications in the medical and biological fields. Drawing inspiration from the remarkable properties of various natural systems, such as the water-repellent lotus leaf, the adhesive gecko foot, the strong yet lightweight spider silk, and the unique optical structures of insect wings, we explore the potential for replicating these features through advanced laser surface modifications. Depending on the nature and architecture of the surface, particular techniques have been designed and developed. We present an in-depth analysis of various methodologies, including laser ablation/evaporation techniques, such as Pulsed Laser Deposition and Matrix-Assisted Pulsed Laser Evaporation, and approaches for laser surface structuring, including two-photon lithography, direct laser interference patterning, laser-induced periodic surface structures, direct laser writing, laser-induced forward transfer, and femtosecond laser ablation of metals in organic solvents. Additionally, specific applications are highlighted with the aim of synthesizing this knowledge and outlining future directions for research that further explore the intersection of laser techniques and biomimetic surfaces, paving the way for advancements in biomedical applications.   #review #peerreviewed #openaccess #callforreading #scientificpublishing #mdpi #mdpicoatings

🌟 Excited to share the Title Story, Volume 10, Issue 4: Fabrication of Hydrogel-Based Composite Fibers and Computer Simulation of the Filler Dynamics in the Composite Flow. 🥼 This paper is authored by Thomas Gruhn, Camilo Ortiz Monsalve, Claudia Müller, Susanne Heid, Aldo R. Boccaccini and Sahar Salehi. 💡 Fibrous structures with anisotropic fillers as composites have found increasing interest in the field of biofabrication since they can mimic the extracellular matrix of anisotropic tissues such as skeletal muscle or nerve tissue. In the present work, the inclusion of anisotropic fillers in hydrogel-based filaments with an interpenetrating polymeric network (IPN) was evaluated and the dynamics of such fillers in the composite flow were analyzed using computational simulations.

Friction is essential in our daily lives by enabling motion and providing traction, but it also results in enormous material and energy losses. Biological species such as snakes display unusual frictional anisotropy via microscopic patterned surfaces, which helps their locomotion. Bioinspired nano/micro texturing with frictional anisotropy can find fascinating applications by designing mobile and immobile surfaces for MEMS/NEMS devices, nano/microrobots, medical devices, etc., as well as controlling the tribological properties and minimizing energy loss in existing industrial components. Our new research article provides insights into controlling the anisotropic frictional behavior using titania nanorod patterning developed through the glancing angle deposition (GLAD) technique. The directional stick-slip friction of the nanopatterned surface can be systematically controlled via rotation of the textured surface with respect to the sliding direction. Our recent work, led by PhD scholar DEBOTTAM DATTA, is now published in ACS Applied Materials and Interfaces (https://lnkd.in/gCAtX_2X).  #friction #StickSlip, #Nanotribology, #NanotexturedSurface, #NanoMission, #DST, #IITDelhi, #Nanosurf, #AtomicForceMicroscopy

Absolute configuration determination by Electron Diffraction. Are you aware that #ElectronDiffraction (#3D ED, #MicroED) can also determine the #absoluteconfiguration of your molecule? Yes, it can! With #dynamicalrefinement. This is a refinement procedure that goes beyond traditional kinematical approximations in electron diffraction analysis. It takes into account the effect of multiple diffraction events contributing to each reflection. This advanced method allows not only for a more precise and reliable structure refinement, but also for determination of the #absolutestructure. #ELDICOScientific has the equipment, skills, software, and knowledge to perform this analysis on your samples. https://lnkd.in/e2utSqcx ELDICO Scientific AG provides service as a measurement so you can see the benefits of using Electron Diffraction on your nanocrystals!

Excited to announce the publication of our paper in the Q1 journal Polymers MDPI, which is Open Access for all to read! Five years after completion, it is rewarding to see my master's work still making significant contributions to its field and being recognized in a leading journal! In this paper, we present elasto-static analysis of dental restorations under various loading conditions, namely occlusal forces and bruxism. We compared the structural responses of three commercial dental composite materials to that of an "intact" molar tooth. Among these, Z100™ by 3M stood out for its superior performance under stress. A significant aspect of our study was the use of computational methods, including the finite element method (FEM) and meshless techniques such as RPIM and NNRPIM. The meshless methods demonstrated excellent accuracy, particularly, near complex curves, compared to conventional FEM. For instance, hereunder, you can see the schematic representation of left-oriented bruxism loading condition modelled in the absence of an adjacent tooth to the left. Also, three contour plots illustrate stress analysis conducted using FEM and meshless methods (RPIM and NNRPIM) on restored molar tooth by Z100™. A special thank you to my master's thesis advisor Jorge Belinha and my dear colleague Behzad Vasheghani Farahani for their invaluable support and contribution to this research.
