In article number 1802745, Yong‐Qiang Li and co‐workers report a robust tumor microenvironment‐responsive theranostic nanoprobe (NanoFlare). By virtue of its anisotropic oligonucleotides‐spike nanostructure, the NanoFlare can enter tumor cells universally regardless of cell type and produce a redox‐activated fluorescence signal. The NanoFlare enables accurate intraoperative margin demarcation of different...
Accurate tumor margin demarcation in situ remains a paramount challenge. Herein, a NanoFlare (also known as spherical‐nucleic‐acid technology) based strategy is reported for in situ tumor margin delineation by transforming and amplifying the pathophysiological redox signals of tumor microenvironment. The NanoFlare designed (named AuNS‐ASON) is based on gold nanostar (AuNS) coated with a dense shell...
