Title: The Innovative Contributions of Donald I. Stimpson

Introduction

Donald I. Stimpson is a notable inventor based in Gurnee, Illinois. He has made significant contributions to the field of optical waveguide technology, holding a total of 5 patents. His work primarily focuses on methods for detecting specific binding in biological samples, showcasing his expertise in the intersection of technology and biology.

Latest Patents

One of his latest patents is titled "Light scattering optical waveguide method for detecting specific binding." This innovative method involves detecting the scattering of light directed into a waveguide, where the scattering results from labels that are specifically bound to the waveguide. The waveguide can be made of transparent plastic or glass, and the binding typically occurs through oligonucleotide hybridization or immunological capture. The light scattering labels may include colloidal metals or non-metals, such as gold, selenium, and latex. Additionally, a light-absorbing member consisting of dye or concentrated particles can enhance the signal. This method allows for real-time monitoring of binding and dissociation, which can be visualized or captured using video imaging technology.

Another significant patent by Stimpson is the "Apparatus and method for determining the quantity of an analyte in a biological sample." This device utilizes a non-transparent support medium to retain a chromatogenic reaction product. The medium is exposed to a light source, which transmits a scattered, uniform response light signal collected by a photosensitive device. The intensity of this response light signal correlates to the amount of analyte present, facilitating quantitative determination.
