79. Alkaline Vents Recreated in Two Dimensions to Study pH Gradients, Precipitation Morphology and Molecule Accumulation

Karen Alim (TU Munich, DE)

Alkaline vents (AV) are hypothesized to have been a setting for the emergence of life, by creating strong gradients across inorganic membranes within chimney structures. In the past, 3-dimensional chimney structures were formed under laboratory conditions, however, no in situ visualisation or testing of the gradients was possible.

We develop a quasi-2-dimensional microfluidic model of...

80. Chemically-driven molecular templating

Talk

The templating of sequence-specific assembly is at the heart of biological complexity; DNA replication, RNA transcription and protein translation are all examples of this process. Extant biological systems exhibit high-fidelity templating of long polymers using purely chemical driving forces; the question of how simpler processes of this kind emerged is at the heart of the origin of...
