Monodisperse albumin particles fabricated by membrane emulsification using anodic porous alumina

Abstract

We obtained monodisperse albumin particles by membrane emulsification using ordered anodic porous alumina with uniform-sized holes. The particle size could be controlled by adjusting the hole size in the alumina emulsification membrane using the linear relationship between the size of particle and the hole. We loaded a fluorescent dye into the albumin particles by adding it to the dispersed phase used for the emulsification. These monodisperse albumin particles with controlled size have potential for use in various applications, in particular, as drug carriers.
