Patent number: 10155797Abstract: The invention provides a binding-induced DNA nanomachine that can be activated by proteins and nucleic acids. This new type of nanomachine hamesses specific target binding to trigger assembly of separate DNA components that are otherwise unable to spontaneously assemble. Three-dimensional DNA tracks of high density are constructed on gold nanoparticles functionalized with hundreds of single-stranded oligonucleotides and tens of an affinity ligand. A DNA swing arm, free in solution, can be linked to a second affinity ligand. Binding of a target molecule to the two ligands brings the swing arm to AuNP and initiates autonomous, stepwise movement of the swing arm around the AuNP surface. The movement of the swing arm generates hundreds of oligonucleotides in response to a single binding event. The new nanomachines have several unique and advantageous features over DNA nanomachines that rely on DNA self-assembly.Type: GrantFiled: September 12, 2016Date of Patent: December 18, 2018Assignee: The Governors of the University of AlbertaInventors: Hongquan Zhang, Xiaochun Le, Xing-Fang Li

Patent number: 10019809Abstract: An underwater camera system includes a projector operable to project a pattern of electromagnetic radiation toward a target object. The electromagnetic radiation includes at least three different wavelengths. A sensor directed toward the target object receives reflected electromagnetic radiation from the target object and stores corresponding image data received from the sensor. One or more processors process the image data to compute a refractive normal according to a wavelength dispersion represented by differences in the image data, and to compute an interface distance corresponding to a distance from a center point of the sensor to a first refractive interface nearest the sensor according to the refractive normal. The processors generate a 3D representation of the target object by back projecting each pixel of the image data at the first, second, and third wavelengths in order to determine an object point location according to the refractive normal and interface distance.Type: GrantFiled: September 19, 2016Date of Patent: July 10, 2018Assignee: The Governors of the University of AlbertaInventors: Herbert Yang, Xida Chen
