Quantum Biosystems today announced the release of raw data access to its
first reads. The company released reads showing an accuracy of more than
99% in non-homopolymer regions and homopolymer indels at a rate of ~10%.
This release allows researchers to evaluate the platform and engage in
its validation and development. It marks a major milestone in the single
molecule electrical sequencing of DNA.
Reagent Free, Silicon Sequencer Has Potential To Be Ultra-low cost
The work reported today by Quantum Biosystems was completed using its
breakthrough novel Quantum Sequencing platform. The platorm allows the
direct sequencing of single stranded DNA and RNA without labelling or
modification, on silicon devices which can be produced on the same
production lines as consumer grade integrated circuits. As the system
uses no proteins or other reagents it is potentially ultra-low cost,
enabling consumer level genome sequencing.
A Fundamental Advance in DNA Sensing Technology
Based on basic research at the University of Osaka, the QB platform uses
sub-nanometer gaps and picoamp level currents to directly detect the
conductance of single DNA and RNA molecules. This breakthrough in
molecular sensing promises to bring to about a fundamentally new class
About Quantum Biosystems
Quantum Biosystems was formed in January of 2013 and is developing 4th
Generation DNA and RNA sequencing systems for the low cost and high
throughput analysis of whole genomes. While present systems require
complicated sample preparation, and costly instruments, the QB platform
has no such barriers to entry and is well positioned to bring about what
some have called "the Democratization of DNA sequencing".
