Abstract

Flexible biosensors with high accuracy and reliable operation in detecting pH and uric acid levels in body fluids are fabricated using well-engineered metal doped porous carbon as electrode material. In this work, gold nanoparticles @N-doped carbon in situ are prepared using natural proteins such as wool keratin (WK) as both a novel carbon precursor and a stabilizer. The reaction parameters are optimized to control size and shape ultimately properties of composite materials. The series of composite materials were prepared and applied for the estimation of biomolecules in the biological fluids such as urine, sweat, saliva. The gold nanoparticles @N-doped which fabricated at 500 °C under customized parameters, mimics A-B type (two different repeating units) polymeric material and displays excellent deprotonation performance (pH sensitivity). Conversely, the composite carbon material with sp² structure prepared at 700 °C is doped with nitrogen and gold nanoparticles, which exhibits good conductivity and electrocatalytic activity for uric acid oxidation. These results will provide new avenues where biological material will be the best start, which can be useful to target contradictory applications through molecular engineering at mesoscale.
