| titleOfInvention | A carbon-dot waveguide based benzoyl peroxide gas sensor |
| abstract | The invention discloses a carbon-dot waveguide-based benzoyl peroxide gas sensor, in particular to a high-selectivity and ultra-sensitive sensing method for detecting benzoyl peroxide (BPO) content in food based on an optical waveguide material. The preparation process mainly includes the following steps: 1) synthesizing carbon dots with colorimetric response to BPO by hydrothermal method; 2) obtaining oil-soluble carbon dots by modification, and coating them on the sensor of a Mach-Zehnder interferometer (MZI). 3) With the increase of BPO concentration, the UV absorption of carbon dots changes obviously, and the discoloration of carbon dots induces the change of refractive index, which leads to the displacement of MZI interference fringes. The offset is linearly related to the concentration of BPO introduced. The invention proposes for the first time to use the optical waveguide sensing technology to detect the BPO content in food ultra-sensitively. Compared with the traditional BPO detection method, the invention has high sensitivity, high speed and good selectivity. It meets the needs of batch preparation in industrial production, making it extremely easy to popularize and apply in practice. |
