Everyone knows how time-consuming, expensive, and difficult the lab testing process is not only for the patients but also for the physicians. First, they have to take patient's samples, then send it to an independent lab, after that wait for the results to come back. Moreover; if it is for diseases like tuberculosis and cancer the course of treatment depends on the DNA of the disease, and that process is even more lengthy and expensive as they have to look for gene mutations. According to an article on popular science, with the help of a new device one can cut directly to the chase. This device can be connected to a normal smartphone and can help discover mutations in cells' DNA and can help save time and resources.
This device has a 3D-printed exterior, which contains two lasers, a white LED, and a lens. It also has a filter that turns a smartphone’s camera into a molecular microscope. To use this phone based microscope, the scientists first take a patient’s sample and treat it with chemicals. This results in the attachment of fluorescent molecules to a specific gene mutation. The device then analyzed the sample. If the device is able to detect those glowing tags, then it is certain that the cell’s DNA contains a mutation. The article also mentioned that this device could be bought for about $500 dollars. This is an awesome device and the price is not that high considering the price of a regular microscope. I think this device will be a lifesaver, in this case, a time saver for many physicians.
