A novel microscale device has been developed to enable the one-step continuous flow assembly of monodisperse nanoscale liposomes using three-dimensional microfluidic hydrodynamic focusing (3D-MHF) in a radially symmetric capillary array. The 3D-MHF flow

This manuscript describes a new method to generate purely diffusive chemical gradients that can be modified in time. The device is simple in its design and easy to use, which makes it amenable to study biological processes that involve static or dynamic

Magnetic connectors for microfluidic applications

Francisco J. Atencia, Gregory A. Cooksey, Andreas Jahn, Justin M. Zook, Wyatt N. Vreeland, Laurie E. Locascio
We present a new type of connector based on a simple idea: using a ring magnet on one side of the microfluidic chip and a disc magnet on the other side to provide the interfacial force necessary to provide a sealed connection between tubing or needles and

A vacuum manifold for rapid world-to-chip connectivity of complex PDMS microdevices

The lack of simple interfaces for microfluidic devices with a large number of inlets significantly limits production and utilization of these devices. In this paper, we describe the fabrication of a reusable manifold that provides rapid world-to-chip
