  • Three dimensional format biochips
    Patent number: 7638464
    Abstract: A biochip is formed with a plurality of optically clear hydrogel cells attached to the top surface of a solid substrate in the form of an array. Each of the cells is formed of a hydrogel of polyethylene glycol, polypropylene glycol or a copolymer thereof having reactive isocyanate groups. Binding entities are immobilized in these cells, which entities are effective to selectively hybridize to or sequester a target biomolecule. Different binding entities are immobilized in different cells in an array to create a biochip that can be used to assay for a number of target biomolecules.
    Type: Grant
    Filed: October 25, 2001
    Date of Patent: December 29, 2009
    Assignee: Biocept, Inc.
    Inventors: Roberto Fagnani, Soonkap Hahn, Xiaofan Dong, Tony Pircher, Sandra Matsumoto, Pavel Tsinberg
