I'm not sure if Eric Winfree was the first to say this; but, i recall hearing him say that the Ned Seeman dna-nanotechnology actually works better in cells than out of them. So, here, we have transcriptors/assemblers, and by doing the Ned Seeman dna-nanotechnologies inside the cell, the nanochemistry can be self-organised inside the cell by Seeman-dnananostructures. Cells are covered by pores that allow certain chemicals in and excrete certain products or even waste. I think that dna-nanostructures punctured into cells has already been demonstrated. So, we could extend the self organising of transcriptor products inside the cell and put a super-pore on the cell that allows the self-organised nanomechanical whatever outside to an extended Seeman/Rothemund dna-structure which can do more assembly. http://www.nanowerk.com/news2/biotech/newsid=29780.php

]]> Comment on Studying environmental impacts of nanoparticles using mesocosms by Stephanie C http://www.foresight.org/nanodot/?p=5542#comment-1369675 Stephanie C Mon, 04 Mar 2013 23:51:43 +0000 http://www.foresight.org/nanodot/?p=5542#comment-1369675 Precisely the right kind of scrutiny, and details about the experimental procedures, results, and interpretations can be found in the journal article. The aspects highlighted in the post center on the experimental design, which allows for realistic exposure scenarios - a requisite for useful data regardless of particle size regime. Regarding possible toxicological effects due to particle size, data pools are slow to emerge (note the broad research objectives of CEINT and the UC CEIN). There are a number of review articles that discuss responsibly why the nanoscale causes concern and the limitations of existing data, for example Seaton 2010: http://intl-rsif.royalsocietypublishing.org/content/7/Suppl_1/S119.full Precisely the right kind of scrutiny, and details about the experimental procedures, results, and interpretations can be found in the journal article.

As you must know, colloidal silver is a potent antibiotic. Silver nitrates are considered hazardous wastes. What has this study proven other than to confirm what we already know?

I wonder what Mr Phoenix thinks of all this latest dna-nanotech stuff; he hates squishy squashy; me? The process might be squishy squashy, but once built, these can be taken out of their water domains and used mechanically. I can only assume you've told the likes of Paul Rothemund, Ned Seeman and others about Mr Phoenix's planar(scaling affects) roadmap mentioned in the previous dna-nanobricks post? Seems there's no dna-nanotech in this years foresight conference; has Drexler and Phoenix given up that much on dna-nanomanufacturing?
