Overview

Peptide-quantum dot conjugates combine the bright, photostable fluorescence of semiconductor quantum dots with the targeting specificity of peptides for advanced bioimaging and sensing.

Conjugation Strategies

Covalent Coupling

  • NHS-ester chemistry
  • Click chemistry (azide-alkyne)
  • Maleimide-thiol coupling

Non-Covalent

  • Electrostatic adsorption
  • His-tag/metal affinity
  • Biotin-streptavidin

Applications

  • Bioimaging: Tumor imaging, cellular tracking
  • Biosensing: FRET-based sensors
  • Drug delivery: Targeted payload release
  • Theranostics: Combined imaging and therapy
