Here, we present all-atom molecular dynamics simulations to investigate the behaviour of bombykol, a model insect pheromone, adsorbed at the water\u2013air interface. This system serves as a proxy for studying the amphiphilic nature of pheromones and their interactions with aerosol particles in the atmosphere. Our simulations reveal the molecular organization of the bombykol monolayer and its adsorption isotherm. A new soft-sticky particle equation\u00a0of state accurately describes the monolayer's behaviour. The analysis uncovers a two-dimensional liquid\u2013gas phase transition within the monolayer. Collective adsorption stabilizes the molecules at the interface and the calculated free energy gain is approximately 2kBT. This value increases under lower estimates of the dew surface concentration, thereby enhancing pheromone adsorption onto aerosols. Overall, our findings hold broad relevance for molecular interface science, atmospheric chemistry and organismal chemical communication, particularly in highlighting the critical role of phase transition phenomena.<\/jats:p>","DOI":"10.1098\/rsif.2025.1229","type":"journal-article","created":{"date-parts":[[2026,10,7]],"date-time":"2026-10-07T00:23:45Z","timestamp":1791332625000},"source":"Crossref","is-referenced-by-count":0,"title":["Collective adsorption of pheromones at the water\u2013air interface"],"prefix":"10.1098","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8822-7669","authenticated-orcid":false,"given":"Ludovic","family":"Jami","sequence":"first","affiliation":[{"name":"Aix Marseille Univ, CNRS, Centrale Med, IRPHE (UMR 7342) 1 , Marseille, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bertrand","family":"Siboulet","sequence":"additional","affiliation":[{"name":"ICSM, CEA, CNRS, ENSCM, Univ.
