At Zimmer Peacock we are often asked about our electrodes, in this video we discuss that the the electrode is just a fraction of the what it takes to make a successful and accurate biosensor and medical diagnostic.
In the video we discuss that the electrodes need to have some biochemistry put onto them to convert them from an electrode to a sensor, and a capillary/microfluidic channel needs to be added to move the sample to the sensor in a reproducible way. Lastly Zimmer and Peacock functionally tests a proportion of the manufactured batch and determines the calibration factors for the batch. The calibration factors are incorporated into a QR code, which is shipped on the sensor. Please see the video for this discussion.
The QR code is one of the most important factors that ensures the biosensor/medical diagnostic's accuracy in the hands of the end user, as the QR code can be automatically read by the final product/reader and the correct calibration of the raw signal will ensure that the customers get an accurate reading of the analyte they are trying to detect.
The key to an accurate medical diagnostic and biosensor is not the reproducibility of the electrode, it is not the printing of the biology onto the electrode, it is not the placement of the microfluidics of on the sensor, it is in the total sum of all these things.
Zimmer and Peacock guarantees success by controlling all these steps and then functionally testing the batch of finished product and giving each batch of final product a unique QR code within the QR code are unique calibration factors that ensures the most accurate measurements in the field.
The QR calibration codes from Zimmer and Peacock are part of the Julia workflow.
