Article Synopsis
- * The phase transition from semiconductor to metal occurs at different temperatures depending on whether measured electrically (63°C) or optically (60°C at a wavelength of 5 micrometers).
- * The study found that the phase transition properties vary with the wavelength in the infrared range, suggesting that these properties can be fine-tuned through wavelength adjustments, and electrical properties provide a more precise characterization.
Aim: To establish a method for screening active substance with scavenging effects on superoxide anion in vitro by designed superoxide dismutase biosensor.
Methods: The enzyme sensor was built by connecting the immobilized CuZnSOD with optical oxygen sensor through a special way. Superoxide anions were generated by auto-oxidation of pyrogallol.
