  • Patent number: 11280017
    Abstract: A layered material suitable as substrate for a three-dimensional cell culture includes a transparent carrier layer and a transparent conductive layer as well as a photoconductive layer comprising titanium oxide phthalocyanine. A method for producing the layered material and an article comprising it and a receiving unit are disclosed. A mold-free method is provided for forming a three-dimensional hydrogel as well as for forming a three-dimensional cell culture by using the layered material or article. Uses of the layered material and of the three-dimensional hydrogel and three-dimensional cell culture are also disclosed.
    Type: Grant
    Filed: December 11, 2015
    Date of Patent: March 22, 2022
    Assignee: City University of Hong Kong
    Inventors: Yajing Shen, Gaole Dai, Wenfeng Wan
  • Patent number: 9921400
    Abstract: A method for manipulating an object for imaging by an imaging device includes the steps of rotating the object about a rotation axis into a plurality of angular positions; capturing an image of the object at each of the plurality of angular positions; and determining a respective translation required of the object for the plurality of angular positions, the translation being along a plane substantially orthogonal to the rotation axis; wherein the respective translation is arranged to align the object to the rotation axis so as to maintain the object within a field of view of the imaging device.
