Shape-Controlled Generation of Gold Nanoparticles Assisted by Dual-Molecules: The Development of Hydrogen Peroxide and Oxidase-Based Biosensors

<div>Generation of GNP solutions with different colors depends on the concentration of H<sub>2</sub>O<sub>2</sub>. (a) Photograph showing the generation of nanoparticle solutions with different colors and intensities after 10 min. (b) Absorbance spectra of GNPs generated with different concentration of H<sub>2</sub>O<sub>2</sub>. From bottom to up: 0, 50, 100, 200, 400, and 600 <i>μ</i>M.</div>
