Engineers at UCLA are working on converting an iPhone into a small laboratory. Weighting less than 2 ounces, the iTube attaches to your phone and analyzes a food sample in about 20 minutes using a colorimetric assay test. The user grinds up a small sample of food with hot water and places it in the tube along with an extraction solvent. After several other testing liquids are added; the phone then captures an image of the sample using its built-in camera and a program app optically analyzes the image for allergen particles down to parts per million. It doesn’t just confirm the presence or absence of peanuts, almonds, hazelnuts, eggs or gluten; it also tells the amount within the sample.
As someone who suffers from severe food allergies; the possibility of such a gadget intrigues me. However I am still skeptical. When in doubt about the specific ingredients of a food, I simply opt not to eat it. True, this practice limits my culinary variety but I figure I can find thrills other ways.
How about you? If you suffer from food allergies would you consider the iTube a useful gadget for home or travel use?
