Researchers in Pennsylvania have developed a technology that uses a smartphone to detect rare proteins in a person’s blood. This technology can help diagnose some forms of cancer and severe brain trauma, which is a difficult task to complete. When one suffers from brain trauma, only a few biomarkers make their way through the blood-brain barrier, making it hard to definitively tell if the trauma is present. Because of the low amount of biomarkers, the normal protein tests usually cannot detect them. This new technology is much more sensitive and can count the amount of proteins that are detected in the blood rather than the technology that has a hard time telling the difference between a vial with no proteins in it and a vial with a few proteins in it. This technology is much more cost-effective and processes quickly, making it a better choice against the bulky, expensive, out of date technology.
