#Who needs water to assemble DNA? Non-aqueous solvent supports DNA NANOTECHNOLOGY Abstract: Scientists around the world are using the programmability of DNA to assemble complex nanometer scale structures.
Until now, however, production of these artificial structures has been limited to water-based environments, because DNA naturally functions inside the watery environment of living cells.
Researchers at the Georgia Institute of technology have shown now that they can assemble DNA NANOSTRUCTURES in a solvent containing no water.
They also discovered that adding a small amount of water to their solvent increases the assembly rate
we have shown that DNA NANOSTRUCTURES can be assembled in a water-free solvent, and that we can mix water with the same solvent to speed up the assembly.
We can also take the structures that were assembled in this solvent mixed with water emove the water by applying vacuum
and have the DNA structures remain intact in the water-free solvent. The assembly rate of DNA NANOSTRUCTURES can be very slow,
and depends strongly on temperature. Raising the temperature increases this rate, but temperatures that are too high can cause the DNA structures to fall apart.
and adding water can adjust the solvent viscosity, which allows for faster assembly compared to the water-free version of the solvent. his solvent changes the rules,
said Isaac Gállego, a postdoctoral researcher in Hud lab and the paper first author. e now have a tool that controls DNA assembly kinetics and thermodynamics all in one solvent.
Glycholine is miscible in water so it can be mixed in any ratio with water to control the kinetics of the assembly process.
For instance, one structure that assembles in six days in pure solvent will assemble in three hours in a glycholine solution containing 10 percent water.
A key feature of the new solvent system is that it does not require changes to existing DNA NANOTECHNOLOGY designs that were developed for water. ou can go back
and forth between hydrated and non-hydrated states, said Gállego. his solvent system preserves the DNA structures that have been developed to work in water.
The solvent system could improve the combined use of metallic nanoparticles and DNA based materials. In the typical aqueous solvents where DNA NANOTECHNOLOGY is performed
The solvent low volatility could also allow storage of assembled DNA structures without the concern that a water-based medium would dry out.
In future work, they hope to use the control provided by water-free solvents to obtain dynamic DNA structural rearrangements that are not possible in water,
both at Georgia Tech. hat was surprising was finding a solvent that allows the assembly of structures more easily than in water.
because DNA NANOTECHNOLOGY was developed in water. The research on water-free solvents grew out of Georgia Tech research into the origins of life.
Hud and colleagues had wondered if the molecules necessary for life, such as the ancestor of DNA, could have developed in a water-free solution.
In some cases he noted, the chemistry necessary to make the molecules of life would be much easier without water being present. his work was inspired by research into the origins of life with the basic question of
whether complex DNA structures could exist in non-aqueous solvents, and we showed that they can,

with a possible focus on filtering biological contaminants from groundwater to make it safe to drink. There are already a number of filters on the market that can do this,
Although the available filters made water safe to drink, they did nothing to mitigate its saltiness so the villagers drinking water tasted bad and eroded pots and pans,
Wright noticed that there were no questions about the waters salty taste. No one had asked ever them about that.
Almost 60 percent of India has groundwater thats noticeably salty so later, after returning to MIT,
which uses a difference in electric potential to pull salt out of water. This type of desalination system has been around since the 1950s,

In an engineering first, Cui and his colleagues used lithium-ion battery technology to create one low-cost catalyst that is capable of driving the entire water-splitting reaction.'
'Our hope is that this technique will lead to the discovery of new catalysts for other reactions beyond water splitting.'
As an alternative, scientists have been trying to develop a cheap and efficient way to extract pure hydrogen from water.
A conventional water-splitting device consists of two electrodes submerged in a water-based electrolyte.
But in 2014, Stanford chemist Hongjie Dai developed a water splitter made of inexpensive nickel and iron that runs on an ordinary 1. 5-volt battery.
'Our water splitter is unique, because we only use one catalyst, nickel-iron oxide, for both electrodes,'said graduate student Haotian Wang,
'This bifunctional catalyst can split water continuously for more than a week with a steady input of just 1. 5 volts of electricity.
That's an unprecedented water-splitting efficiency of 82 percent at room temperature.''In conventional water splitters, the hydrogen and oxygen catalysts often require different electrolytes with different phone acidic,
