    The overall goal of my laboratory is to develop, fabricate and to use plasmonic systems as a ‘photonic environment’, or even as a ‘photonic catalyst’. In general, we aim at opening new routes for photochemical processes/reactions on surfaces by controlling the electromagnetic-field properties at the metal surface, that is, to do, 'chemistry with plasmons'.

    Synthetic design of Pt nanoparticles in carbon nanotubes resistant to corrosion in extreme conditions

    The current research focuses on the investigation of the chemical synthesis of materials to promote renewable and green energies. We have a high expertise in the wet synthesis of Nano-scale materials with the accent on the transition metals, their complexes, organometallic, metallic, and metal-oxide compounds. We developed new chemical routes using soluble organometallic or metal-organic precursors as an alternative to conventional colloidal chemistry and gas phase thin film deposition. These nanoparticles and their assemblies display high activity as catalysts for fuel cells, electrolyzers and redox flow batteries. We were the first to introduce the use of electron magnetic measurements in post-mortem analyses of Li-ion batteries and the first group to publish the operando electron magnetic measurements.

  • Experimental Soft Condensed Matter Physics

    Nano & Advanced Materials

    We employ optical microscopy, light scattering, optical tweezing, and analytical centrifugation, to study phases and phase transitions in systems of colloids, micron-sized particles in a solvent. These systems exhibit liquid, crystalline, glass, gel and liquid-crystalline phases, where the colloidal particles mimick atoms and molecules. Employing confocal microscopy, we follow tens of thousands of individual particles in real time, in either two or three spatial dimensions. This unprecedentedly-detailed experimental information, which is not available with any other experimental technique, allows a much deeper understanding of collective phenomena, such as crystal nucleation, glass formation, and random solid packing to be achieved.

    We also study the interfacial physics of liquid emulsion droplets. Recently, we have discovered a unique interfacial phase transition, which allows the droplet shapes to be temperature-tuned from spherical to faceted, with their bulk remaining liquid.

  • Genomics Research

    Pre-mRNA molecules transcribed from the genome may fold form double-stranded RNA structures. ADAR enzymes bind these structures and deaminate some adenosines to inosines. If these inosines are located in an exon, they will be present in the mature mRNA

    We study the dynamics of genetic information, and how it affects disease, evolution and, behavior. Specifically, we develop technology and algorithms to uncover the full extent of A- to-I RNA editing in human and animal models. We are also develop technology to manipulate the genomic information by recruiting endogenous cellular RNA editing processes.

  • Biomaterials and Advanced Materials group

    Research in my group has been focused on revealing and explaining the fundamental interactions that underlie inorganic material formation in nature, a process known as biomineralization. We particularly make use of our expertise in solid-state NMR spectroscopy to analyze the rudimentary processes of biogenic material formation in atomic/molecular level. Unveiling the structure/activity relations in these specialized biomolecules involved in regulation of solid biomaterial formation has been particularly elusive. Using these findings, we develop new biomaterials for hard tissue applications based on rationale guidelines. We implement NMR characterization in materials research to understand interfaces between nanomaterials at great detail and employ molecular insights to design concept materials that are more environment friendly.

  • Computational Systems Immunology

    An example of a project workflow in our lab, from sample collection to antigen binding and health status prediction

    Our lab develops computational and statistical tools to process and analyze high-throughput biological data. The research is multidisciplinary and involves elements from mathematics, statistics, physics, computer science, biology and medicine. Our main focus is studying the adaptive immune system from a system/repertoire perspective. In particular, we are interested in understanding lymphocyte (T and B cells) repertoire dynamics in healthy individuals as well as in illness states such as infections, autoimmune diseases, aging and cancer. We apply advanced molecular biology methods to produce large sequencing data sets of human lymphocyte receptors, and analyze them using dedicated computational pipelines, in order to obtain meaningful biological insights into the adaptive immune system.

  • Directed Materials Assembly by Optical and Acoustic Forces

    Illustrations of the various directed-assembly methods developed at the Shpaisman group: (a) photo- thermal based modulated laser-induced microbubble technique (M-LIMBT), (b) microstructure formation with standing surface acoustic waves and (c) controlled colloidal formation based on manipulation by optical traps.

    We develop novel concepts based on the idea that forces arising from light (as optical traps or photo- thermal based) and standing acoustic waves can be used to influence the products of ongoing chemical reactions. These forces dictate the spatial distribution of the materials, their mesoscopic structure and could allow the formation of new composite materials. These approaches have many benefits compared to other "bottom-up" methods for material assembly that conventionally rely on accumulation of preformed materials.

    A key feature of our methodology is its modularity, as it could be implemented on various material systems. Due to the flexibility in material choice, this innovative approach will open the door to new ways to act upon materials, with envisioned applications in 3D printing, electronics and sensing.

  • Innovative Surface Engineering of Magnetic/Non-Magnetic Nanomaterials

    Nano & Advanced Materials

    In our lab, we focused on both synthesis of functionalized magnetic NPs and surface modification/engineering of both tungsten disulfide nanotubes and Nano-Diamonds. These set of functional NPs are nontoxic/biocompatible and has a high potential as drug delivery systems, with an important capability of imaging (MRI, X-ray, Fluorescence, … etc.). So far, we focused on the following topics, the use of magnetically responsive NPs in cooperation with Photodynamic Therapy (PDT) drug towards higher drug accumulation by magnetic targeting and therefore, a much more effective PDT output. We also developed an effective innovative nanoscale Delivery System as anti-Leishmania drug, which is based on cerium cation/complex-doped maghemite nanoparticles (Ce·ɣ-Fe2O3-NPs) that are coordinatively bound by both polyethylenemine (PEI) polymer and FDA-approved anti-leishmanial drug pentamidine. Novel surface engineering of nanodiamonds has been also innovatively discovered towards a preliminary wide range of biological and cosmetic applications. Moreover, novel functionalization of inorganic WS2 nanotubes with maghemite NPs resulted in an hybrid magnetic nanocomposite to improve anti-cancer treatment using photothermal therapy (PTT), as well as promoting nanomaterial reduced aggregation together with an additional ability for nanotube versatile second-step surface functionality/engineering.

    In recent years, the world leaders have come to realize that we must change the way we produce and use energy. Being the source of life on earth, from growing crops to producing fresh drinking water through desalination, to sustaining our economies and lifestyles, energy is the most important commodity on earth. The shift to sustainable energy sources raised some new challenges, which include large energy storage for short-, mid- and long-term, to compensate for intermittent power supply, seasonal shortages and strategic storage, respectively, as well as energy for industry and transportation. To tackle these challenges, a cascade of solutions is necessary, out of which hydrogen economy gives the most comprehensive solution. Hydrogen produced from surplus sustainable energy harvested from sunlight, wind and hydropower, can be stored for short and long periods, easily transported between countries and continents and used to produce electricity for the grid, transportation, industry and private homes. Hydrogen economy was already adopted by some of the leading industrial countries, including the EU, Japan and South Korea, which already committed to investments of hundreds of billion  of USD over the coming decade.
