All the emulsions prepared were oil-in-water type and an increase of PDA particle concentration decreased oil droplet diameter. The PDA particles adsorbed to oil\u2013water interface can be crosslinked using poly(ethylene imine) as a crosslinker, and the PDA particle-based colloidosomes were successfully fabricated. Scanning electron microscopy studies of the colloidosomes after removal of inner oil phase revealed a capsule morphology, which is strong evidence for the attachment of PDA particles at the oil\u2013water interface thereby stabilizing the emulsion. The colloidosomes after removal of inner oil phase could retain their capsule morphology, even after sonication. On the other hand, the residues obtained after oil phase removal from the PDA particle-stabilized emulsion prepared in the absence of any crosslinker were broken into small fragments of PDA particle flocs after sonication.<\/jats:p>","DOI":"10.3390\/polym8030062","type":"journal-article","created":{"date-parts":[[2016,2,26]],"date-time":"2016-02-26T10:23:39Z","timestamp":1456482219000},"page":"62","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":56,"title":["Polydopamine Particle as a Particulate Emulsifier"],"prefix":"10.3390","volume":"8","author":[{"given":"Nobuaki","family":"Nishizawa","sequence":"first","affiliation":[{"name":"Department of Applied Chemistry, Osaka Institute of Technology, 5-16-1 Omiya, Asahi-ku, Osaka 535-8585, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ayaka","family":"Kawamura","sequence":"additional","affiliation":[{"name":"Division of Applied Chemistry and Biotechnology, Graduate School of Engineering, Chiba University, 1-33 Yayoi-cho, Inage-ku, Chiba 263-8522, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michinari","family":"Kohri","sequence":"additional","affiliation":[{"name":"Division of Applied Chemistry and Biotechnology, Graduate School of Engineering, Chiba University, 1-33 Yayoi-cho, Inage-ku, Chiba 263-8522, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshinobu","family":"Nakamura","sequence":"additional","affiliation":[{"name":"Department of Applied Chemistry, Osaka Institute of Technology, 5-16-1 Omiya, Asahi-ku, Osaka 535-8585, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2562-9502","authenticated-orcid":false,"given":"Syuji","family":"Fujii","sequence":"additional","affiliation":[{"name":"Department of Applied Chemistry, Osaka Institute of Technology, 5-16-1 Omiya, Asahi-ku, Osaka 535-8585, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2016,2,26]]},"reference":[{"key":"ref_1","first-page":"156","article-title":"Separation of solids in the surface-layers of solutions and \u201csuspensions\u201d (observations on surface-membranes, bubbles, emulsions, and mechanical coagulation)-Preliminary account","volume":"72","author":"Ramsden","year":"1903","journal-title":"Proc.
