Bioinspired Imaging Sensor Advances FGS

There is a high risk of cancer recurrence if even a small number of cancerous cells are left behind after surgical resection. To prevent this, researchers have developed fluorescence-guided surgery (FGS). In FGS, patients are injected with a fluorescent probe that preferentially binds to tumor cells, enabling surgeons to easily identify lesions with the help of specialized endoscopes that emit the necessary excitation light. A team has now reported a novel endoscopic imaging system whose design could greatly accelerate the adoption of multitracer FGS.
