Patent number: 10688126Abstract: Embodiments of the present invention relate to methods for preparing high optical density solutions of nanoparticle, such as nanoplates, silver nanoplates or silver platelet nanoparticles, and to the solutions and substrates prepared by the methods. The process can include the addition of stabilizing agents (e.g., chemical or biological agents bound or otherwise linked to the nanoparticle surface) that stabilize the nanoparticle before, during, and/or after concentration, thereby allowing for the production of a stable, high optical density solution of silver nanoplates. The process can also include increasing the concentration of silver nanoplates within the solution, and thus increasing the solution optical density.Type: GrantFiled: December 9, 2016Date of Patent: June 23, 2020Assignees: nanoComposix, Inc., Sebacia, Inc.Inventors: Steven J. Oldenburg, Martin Miranda, David S. Sebba, Todd J. Harris

Patent number: 9675953Abstract: The disclosed technology relates generally to material systems which include a plurality of particles and methods of making the same. The particles have a core and a shell which encapsulates the core and has at least one atomic element not included in the core. The cores of the particles have a median maximum dimension that is less than 10 microns and a median of at least one axial dimension that is between 10 nm and 500 nm. The shells of the particles have a median thickness that is less than 100 nm, a silicon concentration that is between 10% and 50% on the basis of the weight of the shells, and an aluminum concentration that is between 0.01% and 5% on the basis of the weight of the shells.Type: GrantFiled: October 9, 2014Date of Patent: June 13, 2017Assignee: nanoComposix, Inc.Inventors: Steven J. Oldenburg, Richard K. Baldwin
