Cover Story: Metal detection is important for evaluating metal-related health and diseases and for managing metal-based drug treatments. While DNAzyme-based catalytic beacons have emerged as a powerful class of sensors that can be generalized to detect almost any metal ion with high sensitivity and selectivity, the requirement of laser excitation that causes photobleaching has limited its applications for on-site and real-time detection. To overcome this limitation, Lu and Zhang and colleagues report DNAzyme biosensors that use bioluminescence resonance energy transfer between a luciferase and Cy3 fluorophores for the ratiometric sensing of metal ions. The sensors allow the detection of Zn2+ in serum samples using a smartphone camera. View this paper
