Patent number: 11961628Abstract: Aspects relate to patterned nanostructures having a feature size not including film thickness of below 5 microns. The patterned nanostructures are made up of nanoparticles having an average particle size of less than 100 nm. A nanoparticle composition, which, in some cases, includes a binder, is applied to a substrate. A patterned mold used in concert with electromagnetic radiation function to manipulate the nanoparticle composition in forming the patterned nanostructure. In some embodiments, the patterned mold nanoimprints a pattern onto the nanoparticle composition and the composition is cured through UV or thermal energy. Three-dimensional patterned nanostructures may be formed. A number of patterned nanostructure layers may be prepared and joined together. In some cases, a patterned nanostructure may be formed as a layer that is releasable from the substrate upon which it is initially formed.Type: GrantFiled: January 19, 2023Date of Patent: April 16, 2024Assignee: UNIVERSITY OF MASSACHUSETTSInventors: James Watkins, Michael R.

Patent number: 10527568Abstract: This disclosure relates to methods and devices to count particles of interest, such as cells. The methods include obtaining a fluid sample that may contain particles of interest; counting all types of particles in a portion of the sample using a first electrical differential counter to generate a first total; removing any particles of interest from the portion of the fluid sample; counting any particles remaining in the portion of the fluid sample using a second electrical differential counter after the particles of interest are removed to generate a second total; and calculating a number of particles of interest originally in the fluid sample by subtracting the second total from the first total, wherein the difference is the number of particles of interest in the sample. These methods and related devices can be used, for example, to produce a robust, inexpensive diagnostic kit for CD4+ T cell counting in whole blood samples.Type: GrantFiled: May 21, 2018Date of Patent: January 7, 2020Assignees: The General Hospital Corporation, Massachusetts Institute of Technology, The Board of Trustees of the University of Illinois, Daktari Diagnostics, Inc.Inventors: Nicholas Watkins, Rashid Bashir, William Rodriguez, Xuanhong Cheng, Mehmet Toner, Grace Chen, Aaron Oppenheimer

Publication number: 20070157985Abstract: Tubing or piping for carrying a multiphase flow is provided with means for inducing swirl flow, such that the denser components of the flow tend to the outer wall of the tubing or piping, and less dense components tend to the center of the tubing or piping. The flow thus exhibits a “centrifuge” effect, which prevents lighter or heavier components of the flow from accumulating in upper or lower regions respectively of the tubing or piping, and reduces the risk of airlocks and the like. Preferably, the tubing or piping is in the form of a helix, which may be a low amplitude helix.Type: ApplicationFiled: March 18, 2004Publication date: July 12, 2007Applicant: IMPERIAL COLLEGE INNOVATIONS LIMITEDInventors: Colin Caro, Nicholas Watkins, Philip Birch

The longitudinal cavity of the tubing portion is substantially free of ribs or grooves. The center line of the longitudinal cavity follows a substantially helical path with a helix angle which is less than or equal to 65°. An amplitude of the helix is less than or equal to one half of the internal diameter of the tubing portion.Type: ApplicationFiled: March 18, 2004Publication date: July 5, 2007Inventors: Colin Caro, Nicholas Watkins, Spencer Sherwin
