An interesting article in Wired magazine showing how the camera on a mobile phone can be used to detect cancer DNA sequences via probes labelled with a fluorescent compound. This opens up the possibility of using phones within a dedicated reader for in-the-field molecular diagnostics. As phones are becoming more trusted, we should be able to use them more in diagnostic applications, especially with the added bonus that the communication method is already built into the mobile phone’s function, eliminating the need to develop this from scratch.
