Title: Innovations of Mei-Ling Cheng in Uric Acid Detection

Introduction

Mei-Ling Cheng is a prominent inventor based in Taoyuan, Taiwan. She has made significant contributions to the field of biosensors, particularly in the detection of uric acid. Her innovative work has the potential to impact medical diagnostics and health monitoring.

Latest Patents

Mei-Ling Cheng holds a patent for an "Amperometric sensor for uric acid and method for the same." This invention utilizes polyacrylamide to fix catalase, uricase, and ferrocenecarboxylic acid on a working electrode. The sensor operates by producing hydrogen peroxide when the enzyme reacts with uric acid, allowing for the detection of a reduction current generated from the enzyme on the electrode with an external voltage of 200 mV applied. The sensor achieves a concentration range of 2.5-20 mg/dl for uric acid, with a sensitivity of 5.17 uAcm(mg/dl). The reaction time required for the interaction between the enzyme and uric acid is also noted to be efficient.
