Two secret ingredients of plant microfluidics : water and cellulose
11h / salle C. Brot
Plants offer many elegant examples of microfluidic systems - while some are active and others are passive, all of them are based on two simple ingredients : water and cellulose. In this talk, I will first survey some of the most intriguing uses of water and cellulose in plants. I will then discuss in detail two plant microfluidic systems that are most prosiming for technological applications : the hygroscopic movement of cellulosic tissues and the passive actuation of valves.
