Latest Patents

One of his latest patents is an antimicrobial susceptibility testing device and method for use with portable electronic devices. This innovative method allows for performing antimicrobial susceptibility testing (AST) on a sample using a reader device that mounts on a mobile phone equipped with a camera. The process involves loading a microtiter plate containing wells preloaded with a bacteria-containing sample, growth medium, and drugs of varying concentrations into the reader device. The wells are illuminated using an array of illumination sources, and images are captured with the mobile phone's camera. The images can be processed to classify each well as turbid or not turbid, generating minimum inhibitory concentration (MIC) values and susceptibility characterizations for each drug based on the turbidity classification.

Another notable patent is a micro-plate reader for ELISA testing. This device is designed for use with a portable electronic device that has a camera. It includes an opto-mechanical attachment that can be easily attached or detached from the portable device. The attachment features an array of illumination sources and a slot for receiving an optically transparent plate containing an array of wells. Optical fibers transmit light from each well to a reduced size header, allowing for effective image processing to generate qualitative clinical determinations and quantitative index values for the wells.
