A team of Israeli scientists (Prof. Danny Porath, along with Prof. Alexander Kotlyar) have engineered a huge development. This is 4 stranded DNA along which an electric charge can be passed. This was published in Nature Nanotechnology this week.
This will pave the way for molecular computers which will be smaller, more sophisticated and cheaper. The four-stranded DNA can conduct up to more than 100 picoamperes of electricity up to more than 100 nanometers, 10 times further than had been managed under less rigorous conditions.
Now, all that has to be shown is that the 4 stranded DNA can be made to self assemble like our native 2 stranded variety.
How cool is this?!
