The reconstitution of extracellular matrix (ECM) components in three-dimensional (3D) cell culture environments with microscale precision is a challenging issue. ECM microparticles would potentially be useful as solid particulate scaffolds that ca...
A new microfluidic process was used to generate unique micrometer-sized hierarchical lipid particles having spherical lipid-core and multilamellar-shell structures. The process includes three steps: (1) formation of monodisperse droplets in a none...
Microfluidic technologies are capable of producing small materials such as particles, fibers, and sheets with sizes of several hundred micrometers. In this paper, we briefly introduce our recent progresses on the fabrication of hydrogel materials ...
We present facile strategies for the fabrication of two types of microfluidic devices made of hydrogels using the natural biopolymers, alginate, and gelatin as substrates. The processes presented include the molding-based preparation of hydrogel p...
A simple but versatile microfluidic process is presented for the production of monodisperse polymeric microparticles using non-equilibrium droplets. Oil-in-water (o/w) droplets were formed within microchannels by means of a water-soluble polar org...

Here we present a new approach to rapid formation of collagen gel tubes using microfluidic devices made of phosphate particle-embedding PDMS (PP-PDMS). An acidic solution of collagen, introduced into the PP-PDMS channel, was rapidly transformed in...
