Detection of Viruses Using Synthetic Gene Networks

A strong prospect for the utilization of synthetic gene networks in the context of not only biotechnology, but also medical diagnosis now exists. Engineers have been able to utilize these networks to imitate gene circuits and components of the biological cell for the purpose of research. They can use the synthetic gene networks to direct gene activity, and identify nucleic acids and other relevant molecules. Thus far, there has only been utilization of such a technology in the laboratory. This is due to factors related to safety of this biotechnology, as well as, lack of application in other settings.



As published by Cell Press in the journal Cell, scientists have developed a new type of synthetic gene network that may be safe and practical for use outside of the laboratory. James Collins and other researchers at Harvard University have made progress in the use of synthetic gene networks by creating a paper-based system that does not possess cells, and can be activated safely by the simple act of adding water to the paper. The researchers have tested various clinical applications of this paper-based synthetic gene network for purposes of identification of molecules that are of interest in the field of medicine. They were able to come up with sensors that harness the capacity to recognize molecules of RNA that were produced from genes that allow for the quality of antibacterial resistance in bacteria. They were also able to produce sensors that possessed the ability to detect molecules of RNA that coded for proteins from two particular versions of the Ebola virus. These sensors proved effective in identification when freeze-dried to the paper. This proves significant for clinical applications in the form of diagnosis methodology.



I found this article to be quite interesting due to the transition of a technology once only applicable in laboratory research to one that possesses excellent application to the medical industry. Before reading this article, I was unaware of the ability of engineers to utilize synthetic gene networks to imitate gene circuits and cell components. I find it absolutely amazing that such a biotechnology exists. With all of the recent press coverage regarding the Ebola virus, I found it intriguing that this article mentions the ability for this technology to allow for the detection of proteins found in the presence of certain strains of the Ebola virus. I hope that this new paper-based method will prove efficacious in diagnosis procedures in the future.
