Synthetic biology

Synthetic genetic circuits for programming the structure of material.

Instabilities and oscillations in chemical reactions are of interest since they lead to the emergence of patterns and structures in self organization and other emergent phenomena. One way in which oscillating chemical reactions lead to patterns is through reaction diffusion systems. In this context there has been much interest in how chemical reactions can be coupled, i.e. so that a central oscillating reaction is coupled to other reactions leading to time dependent phenomena also in the second, coupled, reaction. Such systems can mimic pattern formation in biology and have applications in the manufacture of patterned structures. In synthetic biology we are interested in how dynamic behavior can be programmed through genetic circuits. The coupling of regulatory elements that provide positive and negative control leads to instabilities that are seen as oscillations in the system. Examples of such oscillators have been some of the early progress of synthetic biology and with the connection of quorum sensing to the genetic regulation, even the concerted behavior of entire populations can be achieved. The challenge that we are addressing is how to couple the concept of a synthetic core-oscillator to other coupled reactions.The reactions that we are investigating to be coupled as actuators are chosen so that we can use these for structure formation in biosynthetic materials. Such reactions are for example pH-regulating, radical formation, or biosilica forming reactions.

Living factories can revolutionize industry

In traditional chemical industry, product manufacture is based on a series of syntheses. In biological processes, microbes, with their own metabolic activity, transform compounds into products. Already now, significant chemical industry products are manufactured with their help. These are for example monomers and fuels, with new ones being developed all the time. In biological manufacturing, raw materials can be used in more diverse ways and more energy-efficiently, and they can even give these products such structures and added value that otherwise wouldn't be possible.The challenge that we are addressing is first to establish novel cellular chemistries from Carbon(1) to carbon(n) products for chemical and energy industries which are difficult to make using current biotechnology (or chemistry). Second, to Create Synthetic Living Factories that are most carbon and energy efficient , and can compete with petrochemistry, highly sustainable , competitive and efficient production processes.
