Abstract

See full text

Systems and methods for performing non-destructive sensing of a cell or tissue, in vivo or in culture, are provided. The disclosed systems and methods include fabricating and powering one or more implantable integrated circuit (IC) chips that include a network of Photovoltaic (PV) cells for energy harvesting from an optical energy source, an optical modulator integrating Quantum Dot capacitors (QD-caps) for optical data transfer using fluorescence modulation, and sensing circuitry. The IC chip disclosed herein can measure a thickness of around 10 μm, allowing injection into small cells and diffusion through tissue, it is powered and imaged under a microscope and communicates using fluorescence modulation imaged under a microscope.
