Bio Inspired Near-Infrared Fluorescence Sensors: From the Ocean to the Operating Room
Nature has served as an inspiration for novel and elegant designs in architecture, engineering, and science in general. In this talk, I will describe a bio-inspired imaging system based on the visual system of the mantis shrimp for image-guided surgery (IGS). This near-infrared fluorescence (NIRF) imaging device can provide real-time feedback to physicians in the operating room with high fluorophore sensitivity without hampering the surgical workflow. This system employs pixelated tapetal spectral filters, i.e., miniaturized optical interference films, with an array of vertically stacked CMOS detectors to simultaneously sense color, multiple NIRF channels, and 3D shapes of the surgical wound site. I will highlight the technical advantages of our technology compared to state-of-the-art FDA-approved imaging systems for IGS. This bio-inspired sensor has been integrated with wearable devices and used for tracking sentinel lymph nodes in patients with breast cancer. I will also present pre-clinical and clinical results showing the exciting potential of this new technology.
