摘要：
Getting hotter: Hot spots that enable detection of surface-enhanced Raman scattering (SERS) from a single molecule can form at the nanocube-substrate interface by simply depositing a silver nanocube onto a metal substrate (see picture). This new approach offers great simplicity for the formation of robust and fully accessible hot spots, thus providing an effective platform for ultrasensitive detection.
