Patent number: 7129554Abstract: Electrical devices comprised of nanoscopic wires are described, along with methods of their manufacture and use. The nanoscopic wires can be nanotubes, preferably single-walled carbon nanotubes. They can be arranged in crossbar arrays using chemically patterned surfaces for direction, via chemical vapor deposition. Chemical vapor deposition also can be used to form nanotubes in arrays in the presence of directing electric fields, optionally in combination with self-assembled monolayer patterns. Bistable devices are described.Type: GrantFiled: December 11, 2001Date of Patent: October 31, 2006Assignee: President & Fellows of Harvard CollegeInventors: Charles M.

Patent number: 9541522Abstract: The present invention generally relates to nanoscale wires, including to nanoscale wires used as sensors. In some cases, the nanoscale wires may be used to directly determine analytes, even within relatively complicated environments such as blood, unlike many prior art techniques. In some aspects, the nanoscale wire form at least a portion of the gate of a field-effect transistor, and in certain aspects, different periodically-varying voltages or other electrical signals may be applied to the field-effect transistor. For example, in one set of embodiments, sinusoidally-varying voltages of different frequencies may be applied to the nanoscale wire and the source electrode of the field-effect transistor. The electrical conductance or other properties of the nanoscale wire in response to the periodically-varying voltages may then be determined and used to determine binding of the species.Type: GrantFiled: September 12, 2013Date of Patent: January 10, 2017Assignee: President and Fellows of Harvard CollegeInventors: Charles M. Lieber, Hwan Sung Choe, Xueliang Liu

Patent number: 9457128Abstract: The present invention generally relates to nanoscale wires and tissue engineering. In various embodiments, cell scaffolds for growing cells or tissues can be formed that include nanoscale wires that can be connected to electronic circuits extending externally of the cell scaffold. The nanoscale wires may form an integral part of cells or tissues grown from the cell scaffold, and can even be determined or controlled, e.g., using various electronic circuits. This approach allows for the creation of fundamentally new types of functionalized cells and tissues, due to the high degree of electronic control offered by the nanoscale wires and electronic circuits. Accordingly, such cell scaffolds can be used to grow cells or tissues which can be determined and/or controlled at very high resolutions, due to the presence of the nanoscale wires, and such cell scaffolds will find use in a wide variety of novel applications, including applications in tissue engineering, prosthetics, pacemakers, implants, or the like.Type: GrantFiled: September 4, 2013Date of Patent: October 4, 2016Assignee: President and Fellows of Harvard CollegeInventors: Charles M.
