Title: Innovations of David B. Ruffner
Introduction
David B. Ruffner is a prominent inventor based in New York, NY (US). He has made significant contributions to the field of holographic characterization and colloidal science. With a total of 5 patents to his name, Ruffner's work focuses on unique methods for identifying fluid-phase products and analyzing protein aggregates.
Latest Patents
Ruffner's latest patents include "Colloidal fingerprints for soft materials using total holographic characterization." This invention involves systems and methods for uniquely identifying fluid-phase products by endowing them with fingerprints composed of dispersed colloidal particles. The fingerprints can be read on demand using Total Holographic Characterization. A library of chemically inert colloidal particles is developed that can be dispersed into soft materials, encoding user-specified information about the host material. The encoded information can be recovered through high-speed analysis of holographic microscopy images of the dispersed particles. Specifically, holograms of individual colloidal spheres are analyzed to measure each sphere's radius and refractive index, building up the distribution of particle properties one particle at a time. A complete analysis of a colloidal fingerprint requires several thousand single-particle holograms and can be completed in ten minutes. Another significant patent is "Holographic characterization of protein aggregates," which provides systems and methods for determining the size and refractive index of individual aggregates in a solution. This invention allows for the extraction of information regarding morphology and porosity from holographic data.
