Aaron Dubrow, National Science Foundation Aleksei Aksimentiev, a professor of physics at the University of Illinois-Urbana Champaign, used the National Science Foundation-supported Stampede supercomputer to explore a cutting-edge method of DNA sequencing. The method uses an electric field to drive a strand of DNA through a small hole, or "nanopore," either in silicon or a biological membrane. By controlling this process precisely and measuring the change in ionic current as the DNA...

Virus Reveals Physics Of Nanopores
2014-06-17 03:36:51

By Kevin Stacey, Brown University Nanopores may one day lead a revolution in DNA sequencing. By sliding DNA molecules one at a time through tiny holes in a thin membrane, it may be possible to decode long stretches of DNA at lightning speeds. Scientists, however, haven’t quite figured out the physics of how polymer strands like DNA interact with nanopores. Now, with the help of a particular type of virus, researchers from Brown University have shed new light on this nanoscale physics....

No Hear This! Inner-Ear Membrane Uses Nanopores To Separate Sounds
2014-03-19 04:37:47

redOrbit Staff & Wire Reports - Your Universe Online Computers have been largely unable to duplicate a person’s ability to tune into a single voice, even in the midst of background noise, but new research into the biological mechanisms of the human ear could soon change that. According to researchers from the Massachusetts Institute of Technology (MIT), the ear’s selective hearing is due to the evolution of the tectorial membrane, a tiny membrane located inside the inner ear....

Researchers Improve Nanopore-based Technology For Detecting DNA Molecules
2013-11-18 08:34:01

Ecole Polytechnique Fédérale de Lausanne If we wanted to count the number of people in a crowd, we could make on the fly estimates, very likely to be imprecise, or we could ask each person to pass through a turnstile. The latter resembles the model that EPFL researchers have used for creating a "DNA reader" that is able to detect the passage of individual DNA molecules through a tiny hole: a nanopore with integrated graphene transistor. The DNA molecules are diluted in a solution...

Advance In Nanotech Gene Sequencing Technique Made By Penn Research
2013-05-20 14:46:57

University of Pennsylvania The allure of personalized medicine has made new, more efficient ways of sequencing genes a top research priority. One promising technique involves reading DNA bases using changes in electrical current as they are threaded through a nanoscopic hole. Now, a team led by University of Pennsylvania physicists has used solid-state nanopores to differentiate single-stranded DNA molecules containing sequences of a single repeating base. The study was led by Marija...

Synthetic Membrane Channels Built Out Of DNA

Technische Universitaet Muenchen Nanotech structures mimic nature's way of tunneling through cell walls As reported in the journal Science, physicists at the Technische Universitaet Muenchen (TUM) and the University of Michigan have shown that synthetic membrane channels can be constructed through "DNA nanotechnology." This technique employs DNA molecules as programmable building materials for custom-designed, self-assembling, nanometer-scale structures. The researchers present evidence...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'karpos', fruit.
