A Detection of SARS-CoV-2 antigens by deep learning-based SERS technology. The left part is a schematic illustration of the working flow; the right part is a schematic illustration of the SERS mobile detection platform. B Deep learning-based circulating exosome analysis for lung cancer diagnosis, left part show circulation of lung cancer tumor exosomes in the bloodstream and schematic illustration of the collection of SERS spectroscopy of exosomes; right part reveals that spectral dataset is used to train the deep learning models.
