The SymphNode device (left), contains nanoparticles (red dots) that release a drug that blocks the activity of regulatory T cells (green), which suppress the body’s response to solid tumors. At the same time, the SymphNode’s microparticles (black dots) attract and beef up cancer-fighting T cells.

$A diffractive camera design performs class-specific imaging of target objects with instantaneous all-optical erasure of other classes of objects. This diffractive camera consists of transmissive surfaces structured using deep learning to perform selective imaging of target classes of objects positioned at its input field-of-view. Using the same framework, the authors also demonstrated the design of class-specific permutation and class-specific linear transformation cameras, where the objects of a target data class are pixel-wise permuted or linearly transformed following an arbitrarily selected transformation matrix for all-optical class-specific encryption, while the other classes of objects are irreversibly erased from the output image. The success of class-specific diffractive cameras was experimentally demonstrated using terahertz (THz) waves and 3D-printed diffractive layers that selectively imaged only one class (2) of the MNIST handwritten digit dataset, all-optically erasing the other handwritten digits.$
