Lab-based PCR research most accessed article in August
The paper, describing a device for the sub-three-minute amplification of nucleic acids (DNA and RNA) using polymerase chain reaction (PCR), was written by a team that includes lead author and chemical engineer Elizabeth Wheeler and corresponding author and scientist Reg Beer.
Out of 70 papers published as "advanced articles" online by the Analyst in August, the Wheeler-Beer team paper -- "Under three-minute PCR: Probing the limits of fast amplification" -- was the number one most-accessed paper.
"Anything that can improve on a technique that is as broadly used as PCR is going to be of importance," said Vibhuti Patel, deputy editor of Analyst. "The potential application in doctor's offices is very interesting and could make this scientific technique much more widespread."
The standard approach to PCR typically takes about an hour, which is a vast improvement over pre-PCR techniques that required days. However, PCR for point-of-care, emergency-response or widespread monitoring applications needs to be faster still -- on the order of a few minutes, as the LLNL team has achieved.
"We've been pleased with the strong interest this article has generated and the reception our technology has been receiving in the media," Beer said.
Other members of the LLNL team are biologists Christine Hara and Sally Hall, electronics engineer James Frank, biomedical engineer Joshua DeOtte, mechanical technician Bill Benett and mechanical engineer Christopher Spadaccini.
