Although many types of technologies for hydrogel-based cell cultivation have recently been developed, strategies to integrate cell-adhesive micrometer-sized supports with bulk-scale hydrogel platforms have not been fully established. Here, we pres...
Visualization and quantification of intracellular molecules of mammalian cells are crucial steps in clinical diagnosis, drug development, and basic biological research. However, conventional methods rely mostly on labor-intensive, centrifugation-b...
Lateral flow immunoassay devices have revolutionized the style of on-site disease detection and point-of-care testing in the past few decades. The surface nanotopography of a solid substrate is a dominant parameter in the efficiency of antibody im...
We herein propose a new hydrodynamic mechanism of particle separation using dual-depth, lattice-patterned asymmetric microchannel networks. This mechanism utilizes three-dimensional (3D) laminar flow profiles formed at intersections of lattice cha...
Even though a number of microfluidic systems for particle/cell sorting have been proposed, facile and versatile platforms that provide sufficient sorting throughput and good operability are still under development. Here we present a simple but eff...

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...
