Digital Biology is the computer programming of bioassays using digital microfluidic biochips based on electrowetting on dielectric technology. Digital Biology allows for wide scale automation of procedures in synthetic biology by improving efficiency between 1000 to 100000 fold compared to manual laboratory work, for the first time enabling wide scale rapid prototyping for the iterative creation of biological systems. To successfully decentralize the Digital Biology technology, we want to develop Bioflux Technology—a platform that will automate the synthetic biology flow with great medical and commercial potential. Bioflux Technology will be a combination of a software suite for biologists to plan experiments, a microfluidic device, electronics hardware to run the experiments and the required wetware (biological reagents) to perform a wide range of standardized bioassays used in synthetic biology.
About the speaker:
Ruediger Trojok is a Diplom Biologist, that invented a novel contraceptive method based on genetically altered lactic acid bacteria. He worked as a freelance consultant for the office for Technology Assessment by the German Parliament on biohacking and synthetic biology. Since 2014 he works for the Institute for Technology Assessment and Systems Analysis at the Karlsruhe Institute for Technology on the EU program Synenergene. He is currently establishing a citizen science biolab in Berlin, and is supporting open-source biotechnology projects related to public life, politics and the arts.
7. Landauer Information theory
Rolf Landauers:
“Information is not a disembodied
abstract entity; it is always tied to a
physical representation. It is represented
by engraving on a stone tablet, a spin, a
charge, a hole in a punched card, a
mark on paper, or some other
equivalent. This ties the handling of
information to all the possibilities and
restrictions of our real physical word, its
laws of physics and its storehouse of
available parts.”
