Scientists have developed prototype testing strips that don’t need to use cultures to check for infection. They use paper with genetic material built into the fibers to do cell-like processes that normally take days down to 90 minutes. Some saliva or a drop of blood is all this system needs to work. They already have a prototype that detects Ebola. This is kind of like a computer that uses genes as the program, and paper as the operating system.
Since this is in the prototype stage, there is a lot of work still to be done before this technology can become available.
