Area of Science:

  • Electrochemistry
  • Nanomaterials Science
  • Biosensor Technology

Background:

  • Screen-printed electrodes (SPEs) are widely used in electrochemical sensing.
  • Titanate nanowires offer unique properties for electrode modification.
  • Developing sensitive and stable peroxide biosensors is crucial for various applications.

Purpose of the Study:

  • To functionalize titanate nanowires for immobilizing horseradish peroxidase (HRP).
  • To modify screen-printed carbon electrodes with HRP-functionalized titanate nanowires.
  • To develop and characterize a novel peroxide biosensor based on these modified electrodes.

Main Methods:

  • Hydrothermal synthesis of titanate nanowires.
  • Surface modification of nanowires with (3-aminopropyl)trimethoxysilane and glutaraldehyde for HRP immobilization.
  • Electrode modification with HRP-nanowire composite.
  • Electrochemical characterization using cyclic voltammetry and chronoamperometry.

Main Results:

  • Successful immobilization of HRP on titanate nanowires with a surface coverage of 1.62 mg/m².
  • Development of a peroxide biosensor with a low reduction potential of -0.98V (vs Ag, pH 7.0).
  • Linear response range of 40–560 μmol L⁻¹, detection limit of 10.7 μmol L⁻¹, and good stability, reproducibility (RSD 4.7%), and repeatability (RSD 3.3%).

Conclusions:

  • Functionalized titanate nanowires are effective for creating robust peroxide biosensors on SPEs.
  • The developed biosensor exhibits excellent analytical performance for hydrogen peroxide detection.
  • This approach holds promise for practical electrochemical sensing applications.
