Introduction

Wei Xu is an accomplished inventor based in South Bend, IN (US). He has made significant contributions to the field of chemical sensing through his innovative patent. His work focuses on developing advanced detection methods that enhance the accuracy and efficiency of chemical analysis.

Latest Patents

Wei Xu holds a patent for a "Closed bipolar electrode-enabled electrochromic detector for chemical sensing." This device features two separated chambers that perform detection and reporting independently. The analytical reaction of a target molecule in the analytical cell is coupled to and monitored by an electrochromic reaction in the reporting cell. The color change in the reporting cell can be determined spectrophotometrically by RGB analysis of a CCD image acquired via smartphone. This detection method provides a linear response and a low limit of detection due to the redox cycling behavior in both chambers. The BPE-based electrochromic detector can be modified for sensing multiple analytes by integrating three or more sets of detection chemistries into a single device. Multiple analytes with different concentrations can be detected simultaneously within this device. The BPE-based electrochromic device can also be used for metabolite detection, wherein a redox mediator can be combined with specific oxidases to form an electrochemical mediator-electrocatalyst pair that completes redox cycling reactions.
