Continuing our work with microfluidics modeling, simulating and validating gradient generation devices is our latest undertaking at Flow Science. Diffusion based gradients are an integral part of many complex biological processes. One example is how wounds heal due to chemotaxis, where the cells migrate along a chemical gradient. Over the past few years, various approaches to establish and study diffusive gradients have surfaced, but they all suffer their share of problems. Atencia, et al., have proposed an innovative microfluidic gradient generator – the microfluidic palette – that attempts to overcome the known problems with previous approaches. In this blog, we discuss the principle behind the new approach to diffusive gradient generation proposed by Atencia, et al., and present some results of FLOW-3D simulations of such effects.
