  • Publication number: 20210358981
    Abstract: An image-capturing device includes an image sensor. The image sensor includes an upper layer pixel group and a lower layer pixel group that receives the light fluxes from the subject that have passed through each pixel in the upper layer pixel group. The lower layer pixel group includes fourth, fifth and sixth pixels having fourth, fifth and sixth spectral sensitivities, respectively, that are complementary to first, second, and third spectral sensitivities, respectively, of the upper layer pixel group, being arranged in a two-dimensional pattern. Positions of first, second and third pixels in the upper layer pixel group and positions of the fourth, fifth and sixth pixels in the lower layer pixel group are determined such that the fourth, fifth and sixth pixels receive light fluxes that pass through the first, second and third pixels, respectively.

  • Publication number: 20210290769
    Abstract: Materials and methods for targeted and controlled addition of polymers to proteins are provided herein. For example, the methods provided herein can include contacting a protein with (i) an inactive controlled radical polymerization (CRP) initiator blocker that can reacts with amino groups on the protein but cannot serve as an initiator for polymer addition, and (ii) an active CRP initiator that reacts with amino groups on the protein and also includes a group through which a polymer can be coupled to the initiator.
