Parylene Photonic Microimager for Implantable Imaging

We have recently introduced a fully flexible, compact photonic platform, Parylene photonics. Here, we demonstrate a Parylene photonic waveguide array microimager with a light source localization accuracy of 17.04 µm along the x-axis and 30.07 µm along the y-axis over a 200 µm×1000 µm region. We show the feasibility of fluorescent imaging from mouse brain tissue using the microimager array.Clinical Relevance- Implantable microimagers can be used for clinical intraoperative monitoring as well as structural and functional imaging with cell-type specificity in research.
