A smarter way to find cancer-linked lymph nodes Researchers have developed a compact camera inspired by the multiwavelength vision of the mantis shrimp that could help surgeons identify lymph nodes connected to tumors during cancer surgery. The device captures ultraviolet, near-infrared, and visible light using a single chip, enabling real-time assessment of lymph nodes for cancer spread. This innovation draws from the mantis shrimp’s ability to perceive a broad spectrum of light, including ultraviolet and polarized wavelengths invisible to humans. By mimicking this natural capability, the new imaging system allows surgeons to see not only the location of lymph nodes but also whether they harbor hidden cancer cells, potentially improving the accuracy of cancer staging and reducing the need for extensive tissue removal. The technology is currently undergoing clinical trials and represents a significant advancement in intraoperative imaging. By providing immediate feedback during surgery, it may help minimize repeat procedures and improve patient outcomes in cancer treatment.
