The biocompatible polymer solutions were infused using two channels of the microfluidic junction which was also simultaneously fed with a volatile liquid, perfluorohexane using the other channel. The mechanism by which the nanospheres are generated is explained using high speed camera imaging. The polymer concentration (5-50 wt%) and flow rates of the feeds (50-300 µl min(-1)) were important parameters in controlling the nanosphere diameter. The diameter of the polymer nanospheres was found to be in the range of 80-920 nm with a polydispersity index of 11-19 %. The interior structure and surfaces of the nanospheres prepared were studied using advanced microscopy and showed the presence of fine pores and cracks on surface which can be used as drug entrapment locations. date: 2014-12 date_type: published official_url: http://dx.doi.org/10.1007/s11051-014-2626-5 vfaculties: VENG oa_status: green full_text_type: pub pmcid: PMC4255063 language: eng primo: open primo_central: open_green article_type_text: JOURNAL ARTICLE verified: verified_manual elements_source: PubMed elements_id: 1000173 doi: 10.1007/s11051-014-2626-5 pii: 2626 language_elements: ENG lyricists_name: Edirisinghe, Mohan lyricists_name: Kucuk, Israfil lyricists_id: MJEDE48 lyricists_id: IKUCU41 actors_name: Barczynska, Patrycja actors_id: PBARC91 actors_role: owner full_text_status: public publication: Journal of Nanoparticle Research volume: 16 number: 12 pagerange: 2626 issn: 1388-0764 citation: Kucuk, I; Edirisinghe, M; (2014) Microfluidic preparation of polymer nanospheres.
