</html> NOTEBOOK INTRODUCTION

This is a collection of some of our research and ideation that took place during the design workshop conducted by Yashas Shetty, Catherine Kramer and Zack Denfeld. During this stage of our process we tried to understand the context of nanotechnology and the historical relationship between technology, society and metaphors.

We collected exemplars of each, used mind map to assemble and categorize matters of concern, and tested out a range of design possibilities.

Actor Network Mapping Exercise

After discussing a range of ideas from Science & Technology Studies and the Anthropology of Science we did a workshop about Actor Networks. Here were some of the basic mindmapping on Nanotech and Biomod:

http://hackteria.org/wiki/images/thumb/7/74/Mindmap1.JPG/600px-Mindmap1.JPG

We then went on to do a second mind map on how success is defined in this space. Success for who? How is it defined and assessed?

Visiting Lecture by Yamuna Krishnan

On Wed. Sept. 14th 2011 Krishnan from NCBS visited the Srishti BioMod team.

Her talk was First Blueprint, Now Bricks: DNA is Construction Material on the Nanoscale

http://www.ias.ac.in/womeninscience/images/Lila-Daug/photo-final-1-50/p166.jpg

Here are some of the notes

SCALE & THE FRACTAL DIMENSION

We can Create Architecture using DNA
HOW SMALL IS SMALL? Seemingly every Nanotech talk starts with zooming in and talking about Order of Magnitude
What are the metaphors that are constructed in showing the scale shift: Power, Delicate, Fragile
As a comparison from Art/Cultural History: Buckminster Fuller Breathes on a Golf Ball and says something like "the dew from my breath is all of the freshwater on the planet. So take care….

Is there a Fractal Dimension in nanotechnology.
- i.e. we have been talking about the cell as a city or a computer, but we also talk about the planet/Gaia as a city or a computer, how do these scales relate to each other?

Where does EMERGENCE happen - If the cell is an upward metaphor of the world (LIke body metaphor for the world) there is no emergence at the nano scale -
Architecture is the human extension of Geology "Make Architectures Out of Something" see Delanda on Arch. As Geology - Moving Rocks / Inorganic Material Around (Perhaps in Permaculture Architecture IS a Tree not a rock)

Complexity & Control

Do Chemists like Emergence & Complexity. Control?
Self Assembly in an expected way, but what about in an unexpected way?
How many interacting nano-switches would you need in order to have EMERGENT/COMPLEX BEHAVIOR?
Escaping the Overcode -
Not Control but Surprise/Variation
DNA Crystals - Self assembling
How will you know/ would one recognize complex behavior.

HCI of Nanotechnology

Which leads to the question: Who is Nanocomputing for?
What are the HCI implications for Nanocomputing?

How does it include / exclude non-human actors and matters of concern?

Technology is Magic

" We DON'T Need a reason to do Science & Art - We Do it b/c We are Human "
Technology: So Much a Part of Life you don't notice it. Any sufficiently sophisticated technology can not be distinguished magic.
As long as you are noticing technology it hasn't quite integrated itself.

2 Ways of Looking at Technologies

Architecture: Make constructions that reflect your way of seeing the world
Technology: A mode of communication
Switching Devices: What kinds would you use?

Appropriate Nanotechnology?

Tool-Making: recreating all of the functionalities of MacroTech on the NanoScale.
(But what if the current technology doesn't do what we want it too?)

How do you use DNA nanorods on the nanoscale?

Persistence Length = 50 nm
Nature has given us a bunch of rigid rods
DNA - Sugar Phosphate backbone
Glue - Sticky end
Has a code attached to it in the order of the bases (cryptography)

Architecture Types

Rigid Scaffolds or Dynamic Objects (Undergo transitions and is reversible)
Scienctists have to be showing that they are doing useful things
'RIGID // Basket - Rigid but has utility
DYNAMIC // Scissors-

History of NanoTech

DNA can be cut, pasted & copied
Molecular Biologists knew about this 40 & 50 years ago
2 Ways in which you can do SCIENCE
Mode of DISCOVERY (ASking a Question - Biology)
Mode of INVENTION (Create new things for the joy of creating new things - Chemist)
Taking things of lower value and joining them together and making things of more value
Who is the patron? Who allows / prevents the creation of new things

Tools Available

You need to be able to manipulate this material to make new things
DNA-cutting enzymes
DNA-pasting enzymes
DNA-copying enzymes (amplify)
You can do with DNA with what you could do with Microsoft Word

Why This Took Off (in Chemistry)

You are not restricted to the DNA that nature provided you
Ability to make DNA artificially in a chemistry lab
MH Caruthers, SCience, 1985, 230 , 281-285
Frustrated Chemistry - cathch A + B and make them react
ZJ Gardener, Nature 2004, 431

DNA scaffolds in 1D

You can spatially arrange things so they won't see each other
POsition things not he same or opposite sides of pillars

DNA ORAGAMI - SHOULD BE CALLED DNA KNITTING!

(Not Manly Enough?)
A long piece of string wrapped on itself
Flowers on a string - wrap in the shape as a pixel
Scared to see Millions of Smiley Faces

What is NanoComputing's E-Waste
Is there E-waste of Nano-Computing?
Ratiometric pH sensing

IF WE ARE GOING TO DRAW A SHAPE, LET'S AT LEAST BE SURPRISED

Surprise - that something that was artificially engineered could perform qualitatively and quantitatively
Engineering fallacy - Efficiency as a fitness function

STABILITY OF DOMAINS

Give it a choice What does DNA want to do?
If you give DNA a choice….working along with the flexibility of the DNA
The angle of your joint can not be controlled
Let's provide an environment where DNA can decide the curvature
Enough incentive for the DNA would stick - Maximum satisfaction
The angle is enduced by the environment
Allow it different possibilities for being satisfied for maximum base pairing
Giving a system a choice

Icosohydron - made Polymerize into many shapes Flat sheets

DNA nanomachines

JONATHAN BATH AND ANDREW J. TURBERFIELD*

We are learning to build synthetic molecular machinery from DNA. This research is inspired by biological systems in which individual molecules act, singly and in concert, as specialized machines: our ambition is to create new technologies to perform tasks that are currently beyond our reach. DNA nanomachines are made by self-assembly, using techniques that rely on the sequence-specifi c interactions that bind complementary oligonucleotides together in a double helix. They can be activated by interactions with specifi c signalling molecules or by changes in their environment. Devices that change state in response to an external trigger might be used for molecular sensing, intelligent drug delivery or programmable chemical synthesis. Biological molecular motors that carry cargoes within cells have inspired the construction of rudimentary DNA walkers that run along self-assembled tracks. It has even proved possible to create DNA motors that move autonomously, obtaining energy by catalysing the reaction of DNA or RNA fuels.

All-DNA finite-state automata with finite memory

Zhen-Gang Wanga,1, Johann Elbaza,1, F. Remacleb, R. D. Levinea,c,2, and Itamar Willnera,2

Biomolecular logic devices can be applied for sensing and nano- medicine. We built three DNA tweezers that are activated by the inputs Hþ ∕OH− ; Hg2þ ∕cysteine; nucleic acid linker/complemen- tary antilinker to yield a 16-states finite-state automaton. The outputs of the automata are the configuration of the respective tweezers (opened or closed) determined by observing fluorescence from a fluorophore/quencher pair at the end of the arms of the tweezers. The system exhibits a memory because each current state and output depend not only on the source configuration but also on past states and inputs.

An autonomous molecular computer for logical control of gene expression

Yaakov Benenson1,2, Binyamin Gil2, Uri Ben-Dor1, Rivka Adar2 & Ehud Shapiro1,2

Early biomolecular computer research focused on laboratory- scale, human-operated computers for complex computational problems1–7. Recently, simple molecular-scale autonomous pro- grammable computers were demonstrated8–15 allowing both input and output information to be in molecular form. Such computers, using biological molecules as input data and biologi- cally active molecules as outputs, could produce a system for ‘logical’ control of biological processes. Here we describe an autonomous biomolecular computer that, at least in vitro, logi- cal l y anal yses t he level s of messenger RNA speci es, and in response produces a molecule capable of affecting levels of gene expression. The computer operates at a concentration of close to a trillion computers per microlitre and consists of three programmable modules: a computation module, that is, a stochastic molecular automaton12–17; an input module, by which specific mRNA levels or point mutations regulate software molecule concentrations, and hence automaton transition prob- abilities; and an output module, capable of controlled release of a short single-stranded DNA molecule. This approach might be applied in vivo to biochemical sensing, genetic engineering and even medical diagnosis and treatment. As a proof of principle we...

Nanotech & Metaphors

Some of the metaphors currently employed or important to nanotechnology include:

· Casting Spells

· Magic

· Living Factories / Foundaries

       Send the Acorn, Not the Tree
       Computers that grow
       E-Wate: We have a problem with computers that DO NOT KNOW HOW TO DIE

· Speed of Computing (Keeping up with Moore's Law)

- It's fast: But what is it for?!?
- We Know What Technology DOES, But what is it for?!?
- The World's Slowest Computer

Xeno's Paradox of Reality
- Borges -> The Map is Not The Terrain

Jevon's Paradox of Biocomputing / Simulation?

revisiting Ted Nelson:
- Computer Lib / YOU NEED TO UNDERSTAND COMPUTERS NOW! (Do we/ Did we?) http://en.wikipedia.org/wiki/Computer_Lib_/_Dream_Machines

Paul Rothemond TED Talk Notes

http://hackteria.org/wiki/images/thumb/d/d1/P_z_ted_1.png/600px-P_z_ted_1.png

While watching the Paul Rothemond's TED talk these are some of the thoughts and questions that arose:

What is life?
- Can life be categorised by reproduction, metabolism and/or evolution?
- “Life performs computation” How does that quantify or qualify life?

How accurate is the comparison between DNA alterations to the binary system in banking?

“Can we write molecular programs to build technology?”

Today how long do you use a cell phone?
- Was it designed obsolesce?
- So in a way it was designed to die?
- What does it mean for a phone to NOT die?
- In the future if it was possible to grow a phone from a seed, when would the phone know when to stop growing and when would it know to die, and how to die?

http://hackteria.org/wiki/images/thumb/4/40/P_z_ted_3.png/600px-P_z_ted_3.png

Nanotechnology & “Lifecycle Analysis”
- How would or could this change with the introduction of molecular programming?
- What would the death of a product mean?

Why DNA?
- Because “DNA is the cheapest, easiest to understand and the easiest to program material” to create Nano scale computers.
- What is your opinion of this?
