Publication number: 20240138723Abstract: A test strip for sampling a bodily fluid may include multiple layers of a substrate material, an adhesive between at least some of the multiple layers, and a microfluidic channel formed between at least some of the multiple layers. The test strip may further include multiple electrodes on one of the multiple layers, positioned and partially exposed within the microfluidic channel, an additional material positioned at or near an entrance to the microfluidic channel, to selectively limit the flow of at least one of bubbles or debris into the microfluidic channel, and at least one exit port in at least one of the multiple layers to allow for release of pressure from the test strip. In some embodiments, the test strip is a saliva analysis test strip. In some embodiments, the test strip includes multiple exit ports to prevent blockage of sample flow.Type: ApplicationFiled: May 31, 2023Publication date: May 2, 2024Inventors: Thanh Cong Nguyen, Efstratios Skafidas, Duc Hau Huynh, Michael Erlichster, Duc Phuong Nguyen, Hsien Ming, Gursharan Chana, Ting Ting Lee, Chathurika Darshani Abeyrathne, You Liang, Trevor John Kilpatrick, Michael Luther, Alan Dayvault Luther

Publication number: 20240122536Abstract: A method for using saliva to measure at least one substance or physiological parameter of a human or animal subject may involve inserting a first end of a sensor into a handheld saliva testing device. The method may also involve receiving saliva from the subject on a second end of the sensor, moving the saliva from the second end of the sensor to the first end, and processing the saliva with the handheld saliva testing device to provide initial saliva data related to the at least one substance or physiological parameter of the subject. In some embodiments, the sensor remains inserted in the handheld device while the subject deposits saliva on the opposite, free end of the sensor.Type: ApplicationFiled: May 24, 2023Publication date: April 18, 2024Inventors: Efstratios Skafidas, Chathurika Darshani Abeyrathne, Gursharan Chana, Duc Hau Huynh, Trevor John Kilpatrick, Alan D.

Publication number: 20210215662Abstract: A method and system improving the accuracy and/or interpretability of measurements in a body fluid, such as saliva, sweat or urine involves measurement of multiple parameters in a sample with biosensors. One or more biosensors may reflect the concentration of a target biomarker, and one or more biosensors may describe a parameter of the fluid known to impact the function of the first biosensor the way the measurement of the first biosensor should be interpreted.Type: ApplicationFiled: January 14, 2021Publication date: July 15, 2021Inventors: Michael Erlichster, Efstratios Skafidas, Chathurika Darshani Abeyrathne, Ting Ting Lee, Gursharan Chana

Publication number: 20210005322Abstract: A method of measuring an analyte in a bodily fluid sample and combining measurement data from multiple users may involve initiating a wireless connection between a handheld analyzer and a smart computing device on which an analyte analysis application has been downloaded and inserting a test strip into the handheld analyzer. The method may further involve collecting a sample of a bodily fluid on the test strip, measuring, with the handheld analyzer, a concentration of at least one analyte in the sample, wirelessly communicating the measured concentration from the handheld analyzer to the smart computing device, and displaying the measured concentration on the smart computing device. Finally, the method may involve transmitting the measured concentration to a database and organizing data including the measured concentration and at least one additional measured analyte concentration from at least one additional user on the database.Type: ApplicationFiled: July 1, 2020Publication date: January 7, 2021Inventors: Duc Hau Huynh, Michael Erlichster, Thanh Cong Nguyen, Duc Phuong Nguyen, Efstratios Skafidas, Hsien Ming, Gursharan Chana, Ting Ting Lee, Chathurika Darshani Abeyrathne, You Liang, Trevor John Kilpatrick, Michael Luther, Alan Dayvault Luther

Publication number: 20200116664Abstract: An ion sensor includes a substrate, at least one ion selective electrode deposited on the substrate, and a reference electrode deposited on the substrate. The sensor may further include an insulating layer placed over the ion selective electrode and the reference electrode and having openings for the ion selective electrode and the reference electrode, a microfluidic layer placed over at least part of the insulating layer, and a cover layer placed over the microfluidic layer. The reference electrode includes reference electrode material deposited on the substrate and a combination of a polymer and a chloride-containing salt deposited on the reference electrode material.Type: ApplicationFiled: October 10, 2019Publication date: April 16, 2020Applicant: MX3 Diagnostics, Inc.Inventors: Chathurika Darshani ABEYRATHNE, You LIANG, Efstratios SKAFIDAS
