Title: Albert E Chu: Innovator in Reflectometry and Biologically Derived Sample Analysis
Introduction
Albert E Chu is a prominent inventor based in Hillsborough, CA (US), known for his significant contributions to the fields of reflectometry and sample analysis. With a total of 15 patents to his name, he has developed innovative technologies that enhance the understanding and analysis of biological specimens.
Latest Patents
Among his latest patents is a reflectometry system designed with compensation for specimen holder topography and a lock-rejection of system noise. This self-contained system utilizes light reflectivity to examine the intensity of a dyed spot on a device membrane, surrounded by a background area, to discern information about the specimen that produced the spot. In a preferred embodiment, a master clock alternately drives one LED focused on the spot center and then drives two LEDs focused on the background area. Light reflected from both the spot and background is detected by two photodetectors (PDs) spaced apart by a multiple of 90° azimuthal.
Another notable patent is a reagent delivery device and method of use. This invention provides a device and method for filtering a biologically derived sample and mixing it with a reagent. It comprises a fluid container defining a reservoir compartment, including a container outlet, a filter, and a fluid flow-through matrix disposed in a flow path between the reservoir compartment and the container outlet. Water-soluble, dried reagent is retained on the matrix, and means are provided for urging the sample in an aqueous liquid through the filter and matrix for analysis.
