Developments such as this are of interest and value for seeing trends & directions relative to WITII? (What if the impossible isn't?). While I would not pretend for a moment to understand any of the details of DNA level work, what I do see is how advances in nanotechnology are continuing at an every increasing pace and penetrating new levels of scale. The quote below summed it up nicely for me:
"The advances in DNA nanotechnology keep coming, and many observers are wondering if this will be the path that leads us to the next Industrial Revolution. Only time — and many more experiments — will tell."
Nanoscale: Robot Arm Places Atoms and Molecules With 100% Accuracy
Date Published: January 12, 2010
Until the mid-1990s, the term "nanotechnology" referred to the goal of creating vast arrays of nanoscale assemblers to fabricate useful human-scale products from scratch in an entirely automated process and with atomic precision. Since then, the word has come to mean anything from stain-resistant pants to branches of conventional chemistry — generally anything involving nanoscale objects. But the dream of a new Industrial Revolution based on nanoscale manufacturing has not died, as demonstrated most vividly by the work of NYU professor of chemistry Dr. Nadrian Seeman.
Schematics (a) and Atomic Force Micrographs (b) of the Origami Arrays and Capture Molecules. Panel i of (a) illustrates the origami array containing slots for the cassettes and a notch to enable recognition of orientation; the slots and notches are visible in the AFM in (b). Panels ii show the cassettes in place; the color coding in (a) used throughout the schematics is green for the PX state and violet for the JX2 state; the presence of the cassettes is evident in the AFM image in (b). Panels iii illustrate the PX-PX state which captures a triangle pointing towards the notch in the schematic (a) and in the AFM image (b). Panels iv illustrate the PX-JX2 state (a), containing a triangle that points away from the notch, which is evident in the AFM image (b). Panels v illustrate the JX2- PX state which captures a diamond-shaped molecule (a); its shape is visible in the AFM image (b). Panels vi show the linear molecule captured by the JX2-JX2 state, both schematically (a) and in the AFM image (b).
nice ass
