Biologists have developed a smartphone case that can detect cancer-related mutations and diagnose problems with tumours using DNA sequencing. The scientists' research, published recently in the journal Nature Communications, describes how a 3D-printed attachtment can be used to detect mutations using the smarphone's camera. "Molecular diagnostics is typically outsourced to well equipped centralised laboratories, often far from the patient," the authors stated. "We developed molecular assays and portable optical imaging designs that permit on-site diagnostics with a cost-effective mobile phone-based multimodal microscope." The paper describes the mobile phone microscope as a "new milestone for telemedicine technologies." In tests, the case was able to match tradtional lab diagnoses 100% of the time. The cell phone case is the latest in a growing trend of using consumer devices like smartphones within healthcare.
