Purpose
Although the process of amplifying genetic material is remarkable, the hardware needed to do it is relatively simple-- all that is required are three different temperatures which are maintained by the machine, enabling the enzymes and template to do the work of PCR. Current PCR machines cost thousands of dollars, and although there exists open source, DIY PCR machines, their costs still range in the hundreds of dollars. Here at the University of Maryland, we thought that that was an absurd notion. PCR, because of its simplicity and utility, is a robust tool for the diagnosis of many diseases both in the developed and developing world. Making the device cheaper would give more people accessibility to this platform. Accessibility enables further innovation and development of novel methods for disease detection and this in turn enables better and faster diagnosis and treatment both in the developed and developing world.
Another major advantage of "cheap" is education. Here at the University of Maryland, we acknowledge that iGEM is a competition, however we also understand that this competition is also a collaboration. It is an opportunity for all of us to learn from one another and serves as the foundation for future discovery, innovation, and new projects. We hope that our work with the PCR machine will inspire many more teams to tackle designing hardware. We hope that our current collaborations with Duke University foster better and more innovative projects from both of our teams. And most important, we hope that our efforts will be able to inspire the future generation of iGEMer's and the newest members of the iGEM community; high school students.
I remember, along with my fellow teammates, learning about PCR by cutting up little paper nucleotides and putting them into a brown bag and then having our hands act as the "polymerase" that would pluck the nucleotides out and match them with the template strand we were given. I remember taking away very little from this "lab" other than a few paper cuts. In subsequent years, I went through a few internship programs where I was able to learn in greater detail the steps of PCR, eventually learning how to design primers, program the machine, and setup my own reactions. However, I believe that if we truly want to bring synthetic biology to the public, we have to allow them the opportunity to actually do PCR, not through a paper bag which is conceptual understanding, but a real reaction where the end products are the real deal, actual amplified DNA. We still have a ways to go... the enzymes have to become cheaper pipettes need to become cheaper, but designing a below 50 dollar PCR machine is the first step in this endeavor.
Alternative Version:
UMaryland iGEM 2015 is interested in making lab tools more accessible to the public. As part of the DIY revolution, we wanted to build lab tools capable of performing conventional tasks, such as thermocycling and incubation, at a fraction of the cost of typical machines. We also believe that these machines, due to their low cost, could be used as teaching devices in both biology and engineering classrooms.
