Using a cross-disciplinary approach, my group studies <strong>biological processes and systems<\/strong>, specifically the behaviour and response of microorganisms to changes in their environment. We apply concepts and principles from physics, micro- and molecular biology, fluid mechanics and materials sciences to <strong>understand how living organisms adjust or adapt to changes in their environment<\/strong>. This fundamental question can have far-reaching implications, for instance in predicting the future of ecosystems under current climatic shifts, or the status of human health due to changing food habits or lifestyles.<\/p><p><\/p><p><strong>2)\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 <\/strong><strong>How is your expertise relevant in the current COVID context?<\/strong><\/p><p>Since the outbreak of the COVID-19 pandemic, preliminary studies have reported that the pre-infection stability and viability of the SARS-CoV-2 virus is influenced by the nature of the contaminated surfaces. For instance, SARS-CoV-2 virus on plastic and stainless steel surfaces were viable for up to 7 days, whereas on printed paper and copper, this timescale was much shorter (about 4 hours). This <i>viability-timescale<\/i> could have considerable implication on the transmission of the virus, especially through casual surface contacts. Yet we do not know which biophysical principles underpin the virus-surface interactions. V-SIDE is a timely project that aims to fill this fundamental gap,<strong>\u00a0enabling us to link the biophysical mechanisms to the surface-specific viability-timescales<\/strong>.<\/p><p>With the biophysics expertise in my team, we have recently taken the first steps to <strong>tease the virus-surface-environment nexus apart<\/strong>, to uncover how surface properties shape the stability and viability of viral particles. The key questions we are working on are: (i) Why and how do surface properties influence the viability of virus on contaminated surfaces; (ii) How do surface properties, in combination with environmental parameters, determine the viral viability under realistic settings; and (iii) Can we use this unprecedented, yet fundamental knowledge to innovate anti-viral solutions in a scalable and facile manner, that could equip us better not just against COVID-19, but also against recurring novel viral pandemics. Answering these questions could fundamentally change our approach to tackle this current, and future viral pandemics.\u00a0<\/p><p><strong>3)\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 <\/strong><strong>What is your specific role in ongoing COVID projects?<\/strong><\/p><p>From a biophysical standpoint, the surface-specific viability of SARS-CoV-2 virus should depend on the physical interactions between the envelope of SAR-CoV-2 virus, the physico-chemical properties of the contaminated surface, and local environmental variables like temperature, humidity and pH. V-SIDE\u2019s fundamental goal is to <strong>understand how surface properties, under a given environmental setting, impact the structural stability of the virus\u2019 envelope<\/strong>. In doing so, we will simultaneously get a mechanistic insight into the biophysical factors that regulate virus\u2019 ability to infect host cells. Using non-pathogenic mutants and surrogates of the SARS-CoV-2 virus, we will uncover the surface properties that determine the nature and strength of interactions with viruses. Furthermore, the material forming \u2018spikes\u2019 of the coronavirus (Spike proteins) will be used to test the surface-specific interactions, and how these interactions change as a function of the environmental parameters.<\/p><figure class=\"wp-block-dev4-reusable-blocks-image  object-fit--contain\">\n    \n<img decoding=\"async\" class=\"wp-block-image unilux-custom-image-block\"\n                alt=\"\"\n            src=\"https:\/\/www.uni.lu\/wp-content\/uploads\/sites\/11\/2023\/07\/scheme_v_side.png\"\n                    style=\"object-position: 50.00% 50.00%; font-family: &quot;object-fit: contain; object-position: 50.00% 50.00%;&quot;; aspect-ratio: 21\/9; object-fit: contain; width: 100%;\"\n        loading=\"lazy\"\n\/>    <\/figure><p><\/p><p>To achieve this goal in a relevant yet rapid manner, we have proposed an experimental approach that is capable of capturing the relevant physico-chemical interactions using an ELISA-assay, along with high-resolution visualisation platform, to screen candidate surfaces for anti-(SARS-CoV-2) properties. Micro-fabrication and microfluidics will be vital techniques that will allow us to create realistic and relevant experimental conditions under which the virus-surface interactions will be studied. To extract a comprehensive, and statistically reliable data, we will combine<strong>\u00a0high resolution imaging<\/strong> (using Atomic Force and Scanning Electron Microscopy techniques) and <strong>spectroscopic methods<\/strong> to assess the chemical signatures of the surfaces. The experimental data will be used to develop phenomenological models to capture the virus-surface interactions, with a long-term goal of incorporating machine learning methods that will identify surface-specific viabilities of various virus species.\u00a0<\/p><p><strong>4)\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 <\/strong><strong>Could you tell us more about your collaborators?<\/strong><\/p><p>V-SIDE fits within the Physics Meets Biology efforts, under the umbrella initiative <a href=\"https:\/\/cls.uni.lu\/\" target=\"_self\" title=\"\" rel=\"noopener\">Complex Living Systems<\/a>.\u00a0Quite naturally, this will lead to interdisciplinary collaborative activities with colleagues at the LCSB, who are already involved in a number of ongoing projects under FNR\u2019s COVID-19 initiative.
