The integration of dye lasers with microfluidics not only facilitates the implementation of complete "lab-on-a-chip" systems, but also allows the dynamical control of the laser properties which is not achievable with solid-state optical components. We review the recent demonstrations of on-chip liquid dye lasers and some of the pre-microfluidics era microscopic dye lasers which are also amenable to microfluidic implementation. Potential applications and future directions are discussed. © Springer-Verlag 2007.text::journal::journal article::review article
