Title: Innovations by David Polley in Microorganism Detection
Introduction
David Polley is an accomplished inventor based in Cockeysville, MD (US). He has made significant contributions to the field of microorganism detection, holding 2 patents that showcase his innovative approach to improving sensitivity in detecting microbial growth.
Latest Patents
One of his latest patents is a "Reactance and capacitance sensing platform for detecting microorganisms." This system and method enhance sensitivity to microorganism growth by utilizing a signal processing electronic circuit connected to a consumable or vessel through two or more electrodes. These electrodes fully penetrate the vessel and are in contact with the fluid contents. The electronic circuit is designed to detect a component of the total impedance of the sample, specifically the "out-of-phase" or imaginary reactance component, which responds sensitively to organism growth in a frequency-dependent manner. The system effectively detects changes in both the composition of charged molecules in the liquid matrix and the number of microorganisms by monitoring the sample for changes in this parameter. This innovative approach results in a 5-70% reduction in time-to-detection (TTD). The system is versatile, capable of detecting organisms in various vessel shapes, volumes, and matrix formats. The electrodes are fully immersed in a continuous body of liquid sample, and both the distance between electrodes and voltage inputs can be adjusted to optimize detection.
