Passive micromixer for luminol-peroxide chemiluminescence detection [PDF]

The Analyst, 2011
This paper reports a microchip with an integrated passive micromixer based on chaotic advection. The micromixer with staggered herringbone structures was used for luminol-peroxide chemiluminescence detection. The micromixer was examined to assess its suitability for chemiluminescence reaction.
