Description
(a)気体中または真空中の条件下で浮遊輸送される液滴粒子であって、
(b)前記条件下で蒸発する液体と目的成分物質と臨界ミセル濃度未満の界面活性剤とを含む混合溶液が霧化された直径100μm以下の液滴から前記液体が蒸発して濃縮された目的成分物質と、
(c)液滴粒子の表面全体に、自己凝集して分子が逆ミセル様に並ぶことによって、前記液体が蒸発することを抑制する膜を形成し、臨界ミセル濃度を上回る界面活性剤とを含み、
(d)混合溶液における界面活性剤の濃度に対応する直径10μm以下の粒径を有する球状であることを特徴とする液滴粒子である。
図1は、本実施形態の液滴粒子の形成過程を説明する図である。
図2は本発明の第1実施形態における液滴粒子の生成方法を示すステップ図であり、図3は第1実施形態における液滴粒子の生成装置の構成の概略を示すブロック図である。
前述の構成の液滴粒子の生成装置(図4,図5A)を用いて、液滴粒子の生成を行った。なお、水溶液(水)としては純水を用い、これに、界面活性剤として、代表的なアニオン界面活性剤である、直鎖アルキル(ドデシル)ベンゼンスルホン酸ナトリウム〔以下、LASと略称する〕を、10~100μM(M=mol/L)添加して、微小サイズの液滴粒子(エアロ・ナノ・ミセル)の生成の確認を行った。ちなみに、LASの臨界ミセル濃度〔cmc〕は、1.2mMol/L(1200μM)である。
図5Bに示すように、水溶液噴霧手段1の内管と外管の間から、1.5L/分相当の流量の乾燥空気を流しながら、内管から、流量2.0μL/分の割合で、LASを添加した純水を、図示下側の液滴養生部2に向けて噴射した。そして、液滴養生部2の底部に位置する溶液回収部には、測定機器として、光散乱式のパーティクルカウンター(リオン社製KC-01E)を直接接続して、この液滴養生部2の底部まで到達する液滴粒子(エアロミセル)の個数と粒径分布とを、実験ごとに1分間計測した。なお、LASを添加しない純水のテスト噴射で観測される液滴粒子は、極めて少ない。
