Patent number: 11654404Abstract: Embodiments described herein may be useful for optofluidic devices. For example, optofluidic devices using dynamic fluid lens materials represent an ideal platform to create versatile, reconfigurable, refractive optical components. For example, the articles described herein may be useful as fluidic tunable compound micro-lenses. Such compound micro-lenses may be composed of two or more components (e.g., two or more inner phases) that form stable bi-phase emulsion droplets in outer phases (e.g., aqueous media). In some embodiments, the articles described herein may be useful as light emitting droplets. Advantageously, the plurality of droplets may be configured such that light rays may modified (e.g., via stimulation of the droplets, exposure to an analyte such as a pathogen) to have a detectable emission intensity and/or angle of maximum emission intensity under a particular set of conditions.Type: GrantFiled: May 17, 2019Date of Patent: May 23, 2023Assignee: Massachusetts Institute of TechnologyInventors: Timothy M.

Patent number: 11325114Abstract: Methods for forming an interconnected network of solid material and pores, with metal residing only at the air/solid interface of the interconnected network structure are described. In certain embodiments, nanoparticle decorated sacrificial particles can be used as sacrificial templates for the formation of a porous structure having an interconnected network of solid material and interconnected network of pores. The nanoparticles reside predominantly at the air/solid interface and allow further growth and accessibility of the nanoparticles at defined positions of the interconnected structure. SEM and TEM measurements reveal the formation of 3D interconnected porous structures with nanoparticles residing predominantly at the air/solid interface of the interconnected structure.Type: GrantFiled: April 22, 2019Date of Patent: May 10, 2022Assignee: PRESIDENT AND FELLOWS OF HARVARD COLLEGEInventors: Joanna Aizenberg, Tanya Shirman, Nicolas Vogel, Mathias Kolle, Michael Aizenberg

Patent number: 10422947Abstract: The rolled photonic fibers presents two codependent, technologically exploitable features for light and color manipulation: regularity on the nanoscale that is superposed with microscale cylindrical symmetry, resulting in wavelength selective scattering of light in a wide range of directions. The bio-inspired photonic fibers combine the spectral filtering capabilities and color brilliance of a planar Bragg stack compounded with a large angular scattering range introduced by the microscale curvature, which also decreases the strong directional chromaticity variation usually associated with flat multilayer reflectors. Transparent and elastic synthetic materials equip the multilayer interference fibers with high reflectance that is dynamically tuned by longitudinal mechanical strain. A two-fold elongation of the elastic fibers results in a shift of reflection peak center wavelength of over 200 nm.Type: GrantFiled: October 19, 2018Date of Patent: September 24, 2019Assignees: President and Fellows of Harvard College, University of ExeterInventors: Joanna Aizenberg, Mathias Kolle, Peter Vukusic, Robert D.
