Following “significant concerns” raised by outside researchers and a formal university investigation, a group of authors in Taiwan has retracted a Nature Nanotechnology paper on DNA sequencing after they “could not reproduce the results of the work,” or even provide “a complete set of raw data for the original experiments.”
The paper, “DNA sequencing using electrical conductance measurements of a DNA polymerase,” describes a technology to sequence single DNA molecules — a technique that the authors, all based at National Chiao Tung University in Taiwan, suggest could be used to “cheaply and quickly” sequence DNA.
Concerns about the paper’s data were first raised in May 2013 by the community, according to an editorial from the journal. Then, the journal asked the university to investigate, says “Notes on a retraction”: Continue reading “Significant concerns” and formal investigation unwind Nature Nanotech sequencing paper
