Title: R Dale Delk: Innovator in Electrochemical Biosensors
Introduction
R Dale Delk is a notable inventor based in Muncie, Indiana, with a focus on advancements in electrochemical biosensors. He holds a total of four patents, showcasing his commitment to innovation in the field of medical diagnostics.
Latest Patents
One of his latest inventions is an electrochemical biosensor test strip that incorporates four new features. This test strip includes an indentation for tactile feedback regarding the location of the sample application port. The sample application port leads to a capillary test chamber that contains a test reagent. The wet reagent consists of 0.2% to 2% by weight polyethylene oxide, with a mean molecular weight ranging from 100 kilodaltons to 900 kilodaltons. This formulation enhances the hydrophilicity and durability of the dried reagent, making it more resilient during processing steps, such as mechanical punching and user manipulation. Additionally, the capillary test chamber's roof features a transparent or translucent window that serves as a 'fill to here' line, indicating when an adequate liquid sample, such as blood, has been added for accurate testing. The test strip may also include a notch at the sample application port to mitigate 'dose hesitation.'
