Efficient light harvesting, which is essential for their survival and ecological fitness, is orchestrated through a suite of photoreceptors and light-responsive molecular actuators. These components drive regulatory cascades that shape gene expression, protein activity, and behavioural responses such as phototaxis.\nOur recent discoveries with sulfur-metabolising bacteria have demonstrated that tiny granular intracellular structures could possess distinct optical properties capable of interacting with light fields within single cells. Building on this insight, MicroPAS: Microbial Photonics Across Scales, introduces a transformative conceptual and experimental framework that treats organelles as active optical elements, governed by the fundamental physics of light\u2013matter interactions.\nThe project will employ an integrated toolkit of advanced microscopy, spectroscopy, and data-driven numerical modelling to investigate both laboratory-cultivated and naturally occurring sulfur-bacterial species. Through this multi-scale approach, MicroPAS will determine how the composition and distribution of such organelles define optical properties and modes internally, and thereby enable dynamic light guidance within living cells.\nFurther afar, this ERC-CoG\u2013funded project will probe emergent collective behaviour, asking how populations of bacteria might self-organise their optical responses. Such collective regulation could enhance light penetration, modify scattering patterns, or give rise to nonlinear optical phenomena, ultimately enabling the engineering of living photonic circuits that rely on biological feedback loops.\nBy revealing how intracellular light modulation shapes microbial physiology, ecological performance, and adaptive behaviour, MicroPAS will lay the foundation for a new, data-rich bio-photonic paradigm. The project will pave the way for next-generation Living Optical Matter, inspired directly by nature\u2019s strategies for manipulating light with exquisite precision.\nThe project will be directed by Prof. Anupam Sengupta, Head of the Physics of Living Matter Group at the University of Luxembourg.\n","rp_start_date":"2026-04-01 00:00:00","rp_duration":60,"rp_main_funder":"ERC Consolidator Grant ","rp_other_funders":["Horizon Europe"],"rp_external_partners":[],"rp_keywords":[],"rp_members":[{"name":"Anupam SENGUPTA","isPI":true,"isExternal":false,"featuredImageUrl":"https:\/\/www.uni.lu\/en\/person-image\/NTAwMzEzODBfX0FudXBhbSBTRU5HVVBUQQ==","detailsPageUrl":"https:\/\/www.uni.lu\/fstm-en\/people\/anupam-sengupta\/","id":"50031380"},{"name":"Jana KRIER KABASTOVA","isPI":false,"isExternal":false,"featuredImageUrl":"https:\/\/www.uni.lu\/en\/person-image\/NTAwNjc4MjBfX0phbmEgS1JJRVIgS0FCQVNUT1ZB","detailsPageUrl":"https:\/\/www.uni.lu\/fstm-en\/people\/jana-krier-kabastova\/","id":"50067820"},{"name":"Georgia KAPROU","isPI":false,"isExternal":false,"featuredImageUrl":"https:\/\/www.uni.lu\/en\/person-image\/NTAwNDE4MzRfX0dlb3JnaWEgS0FQUk9V","detailsPageUrl":"https:\/\/www.uni.lu\/fstm-en\/people\/georgia-kaprou\/","id":"50041834"}]},"research-project-status":[],"research-project-type":[268],"field-of-interest":[295],"organisation":[80,29,91],"authorship":[325],"acf":[],"_links":{"self":[{"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/core-researches\/43797"}],"collection":[{"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/core-researches"}],"about":[{"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/types\/core-researches"}],"author":[{"embeddable":true,"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/users\/325"}],"version-history":[{"count":1,"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/core-researches\/43797\/revisions"}],"predecessor-version":[{"id":43799,"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/core-researches\/43797\/revisions\/43799"}],"wp:authorship":[{"embeddable":true,"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/users\/325"}],"wp:attachment":[{"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/media?parent=43797"}],"wp:term":[{"taxonomy":"research-project-status","embeddable":true,"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/research-project-status?post=43797"},{"taxonomy":"research-project-type","embeddable":true,"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/research-project-type?post=43797"},{"taxonomy":"field-of-interest","embeddable":true,"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/field-of-interest?post=43797"},{"taxonomy":"organisation","embeddable":true,"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/organisation?post=43797"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
