ONLINE COVER When Small Meets Smart. A miniaturized nuclear magnetic resonance (NMR) device detects scarce cancer cells in tissue biopsies with speed and accuracy, reported by Haun et al. in this issue. The coils generate radio frequency magnetic fields that excite protons in the tissue samples resulting in NMR signals that can be used to identify a cancer protein signature. This tiny portable micro-NMR machine operated by a smart phone can be used at the patient’s bedside and is able to deliver an accurate cancer diagnosis in under 60 minutes. [CREDIT: H. LEE AND R.
