2 CAD-CAM: Agilent Chip Design / Assembly OptMAGE Genetic Design via Local Search (GDLS) Measurements: In situ sequencing Morphology & behavior Selection (evolution): Cell sorting Sensor set +/- Selector sets 2 Chassis (&BioFab) Goals George Church, Carlos Bustamante, Tom Knight Microbes, organelles, in vitro, plant, animal

3 Bakal, et al. Science 316, 1753 3 145 morphological measures

4 Bakal, et al. Science 316, 1753 4 Phenoclusters Represent Functionally Related Genes.

5 5 In situ sequencing Zhang et al Nat Gen 38:382. Goal: Go from 12-plex to >1000-plex

6 6 From open-access Sequencer to Bio-Fab Polonator 1. Select ‘perfect part’ sequences 2. Device characterization 3. Cell sorting (FACS) Digital micromirrors Flow- cell billion beads or cells/run Photo-labile immobilization Rich Terry
