SUMMARY:Microfluidic Networks of the Oscillatory Chemical Reactions
DESCRIPTION:Featuring Seth Fraden\, Brandeis University\n\nPart of the Biop
	hysics/Condensed Matter Seminar Series.\n\nOur goal is to create autonomous
	\, programmable active materials. A bioinspired example is the sinuous moti
	on of a lamprey\, in which neurons running down the spinal column are excit
	ed in sequence causing the musculature to contract\, thereby propelling the
	 lamprey. The control elements mimicking neurons are microscopic chemical r
	eactors containing the Belousov-Zhabotinsky (BZ) reaction\, while the actua
	tors mimicking musculature are embodied by gels whose volume is sensitive t
	o the chemistry.\n \nSeveral microfluidic based experimental systems of net
	works of non-linear chemical oscillators are presented. The experiments are
	 analyzed with theory for 2D planar arrays of oscillators with nearest neig
	hbor coupling involving both inhibitory and excitatory species. We explore 
	phenomena such as synchronization\, oscillator death and assess the number 
	of attractors\, as well as their basin of attraction\, as a function of the
	 topology of the network and the heterogeneity of the oscillators and their
	 coupling strength.
