  • Publication number: 20250312493
    Abstract: Provided are fluorescent nanoparticle and related methods of using the fluorescent nanoparticles for imaging tumors. The fluorescent nanoparticle comprises a gelatin matrix; and a fluorophore encapsulated within the gelatin matrix and ionically-bound to the gelatin matrix. The encapsulated fluorophore has an encapsulation concentration selected to provide: quenching of fluorophore encapsulated within the gelatin matrix and a substantial fluorescence for the fluorophore released from the gelatin matrix.

  • Patent number: 12130180
    Abstract: An image sensor capable of recording both spectral and polarization properties of light using a single chip device includes an at least 2048 by 2048 array of superpixels. Each superpixel includes an array of spectral pixels, and an adjacent array of polarization pixels. Each spectral pixel includes a spectral filter and a stack of photodiodes, where each photodiode has a different quantum efficiency and is, therefore, sensitive to a different wavelength of light passed by the spectral filter. Each polarization pixel includes a polarization filter and a stack of photodiodes, similar to the spectral pixel photodiode stacks.
