A new fluorescent nanosensor detects antimony ions (Sb(3+)) using quantum dot (QD) nanoparticles. This novel sensor offers a simple, sensitive, and selective method for determining antimony in water samples.

Area of Science:

  • Nanotechnology
  • Analytical Chemistry
  • Environmental Science

Background:

  • Antimony (Sb(3+)) is a toxic heavy metal pollutant.
  • Accurate and sensitive detection methods for antimony are crucial for environmental monitoring.
  • Existing methods for antimony detection can be complex or lack sensitivity.

Purpose of the Study:

  • To develop a novel fluorescent nanosensor for the sensitive and selective determination of antimony ions (Sb(3+)).
  • To utilize thioglycolic acid (TGA)-capped Cadmium Telluride (CdTe) quantum dot (QD) nanoparticles conjugated with Bovine Serum Albumin (BSA) as a receptor-fluorophore system.
  • To establish a simple, fast, and highly selective assay for antimony detection in real water samples.

Main Methods:

  • Synthesis of water-soluble TGA-capped CdTe QDs via a hydrothermal route.

  • Conjugation of BSA to TGA-capped CdTe QDs through an amide linkage.
  • Utilizing the fluorescence quenching mechanism of QDs upon antimony ion binding to BSA for detection.

    • Main Results:

    • The nanosensor demonstrated excellent linearity for Sb(3+) detection in the range of 0.10-22.0 µg L⁻¹.
    • A low detection limit below 2.94 x 10⁻⁸ g L⁻¹ and a relative standard deviation (RSD) of 2.54% were achieved.
    • The sensor exhibited good selectivity against potential interfering substances and was successfully applied to real water samples.

    Conclusions:

    • A novel, simple, fast, sensitive, and highly selective fluorescent nanosensor for Sb(3+) determination was successfully developed.
    • The QD nanoparticle-based sensor provides a promising tool for monitoring antimony contamination in environmental water.
    • The TGA-QD-BSA system offers a robust receptor-fluorophore platform for heavy metal ion sensing.
