Microfluidic Microdialysis: Spatiotemporal Control over Solution Microenvironments Using Integrated Hydrogel Membrane Microwindows

Abstract

Inspired by the two-step circulation-diffusion distribution strategy of human circulatory system, scientists have developed ``hydrogel membrane microwindows'' in microfludic devices as a powerful and versatile means to establish and manipulate chemical and electric-field gradients with speed.
