Janus (Pt\u2013SiO2 and Pt\u2013MF, where MF is melamine formaldehyde) colloids do not spontaneously adhere to POPC or DOPC bilayers, but by applying external forces via centrifugation we were able to force the contact between the particles and the membranes, which may result in a partial engulfment state of the particle. Surface properties of the Janus colloids play a crucial role in the driven particle engulfment by vesicles. Engulfment of the silica and platinum regions of the Janus particles can be observed, whereas the polymer (MF) region does not show any affinity towards the lipid bilayer. By using fluorescence microscopy, we were able to monitor the particle orientation and measure the rotational dynamics of a single Janus particle engulfed by a vesicle. By adding hydrogen peroxide to the solution, particle self-propulsion was used to perform an active transport of a giant vesicle by a single active particle. Finally, we observe that partially engulfed particles experience a membrane curvature-induced force, which pushes the colloids towards the bottom where the membrane curvature is the lowest.<\/jats:p>","DOI":"10.3390\/nano12091434","type":"journal-article","created":{"date-parts":[[2022,4,23]],"date-time":"2022-04-23T21:39:45Z","timestamp":1650749985000},"page":"1434","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Driven Engulfment of Janus Particles by Giant Vesicles in and out of Thermal Equilibrium"],"prefix":"10.3390","volume":"12","author":[{"given":"Vaibhav","family":"Sharma","sequence":"first","affiliation":[{"name":"Institute Charles Sadron, CNRS UPR22, University of Strasbourg, 23 Rue du Loess, 67034 Strasbourg, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3952-0498","authenticated-orcid":false,"given":"Carlos M.","family":"Marques","sequence":"additional","affiliation":[{"name":"Institute Charles Sadron, CNRS UPR22, University of Strasbourg, 23 Rue du Loess, 67034 Strasbourg, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5524-4323","authenticated-orcid":false,"given":"Antonio","family":"Stocco","sequence":"additional","affiliation":[{"name":"Institute Charles Sadron, CNRS UPR22, University of Strasbourg, 23 Rue du Loess, 67034 Strasbourg, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,4,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"8655","DOI":"10.1021\/acsnano.5b03184","article-title":"Physical Principles of Nanoparticle Cellular Endocytosis","volume":"9","author":"Zhang","year":"2015","journal-title":"ACS Nano"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"5359","DOI":"10.1039\/c0sm00396d","article-title":"Shape deformation of giant vesicles encapsulating charged colloidal particles","volume":"6","author":"Natsume","year":"2010","journal-title":"Soft Matter"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"3704","DOI":"10.1021\/acsnano.5b01285","article-title":"Critical particle sizes for the engulfment of nanoparticles by membranes and vesicles with bilayer asymmetry","volume":"9","author":"Lipowsky","year":"2015","journal-title":"ACS Nano"},{"key":"ref_4","doi-asserted-by":"crossref","first-page":"3533","DOI":"10.1039\/D0SM01758B","article-title":"More than just a barrier: Using physical models to couple membrane shape to cell function","volume":"17","author":"Frey","year":"2021","journal-title":"Soft Matter"},{"key":"ref_5","doi-asserted-by":"crossref","unstructured":"Petithory, T., Pieuchot, L., Josien, L., Ponche, A., Anselme, K., and Vonna, L.
