We demonstrate optical control over the distance between gold nanoparticles linked by proteins. Laser light induces protein motion, altering nanoparticle spacing by approximately 0.5 nm, observable via surface-enhanced Raman scattering (SERS).

Area of Science:

  • Nanotechnology
  • Biophysics
  • Spectroscopy

Background:

  • Gold nanoparticles are widely used in biosensing and nanophotonics.
  • Controlling inter-nanoparticle distances is crucial for tuning optical properties.
  • Protein-mediated assembly offers precise control at the nanoscale.

Purpose of the Study:

  • To optically manipulate the distance between protein-linked gold nanoparticles.
  • To investigate the mechanism of laser-induced protein motion.
  • To quantify the change in inter-nanoparticle distance using Rayleigh scattering spectroscopy.

Main Methods:

  • Fabrication of individual protein-linked gold nanoparticle dimers.
  • Characterization of plasmon coupling using Rayleigh scattering spectroscopy.

  • Application of low-intensity laser light to induce Raman-induced motion.
  • Detection of surface-enhanced Raman scattering (SERS) from linker proteins.

    • Main Results:

    • Optical control of inter-nanoparticle distance was achieved.
    • A change in distance of approximately 0.5 nm was observed.
    • The observed distance change correlated with the presence of SERS signals from proteins.
    • Low laser intensity (50 microW/microm2) was sufficient to induce motion.

    Conclusions:

    • Raman-induced motion of linker proteins can optically alter nanoparticle spacing.
    • Rayleigh scattering spectroscopy is a viable method for measuring these nanoscale changes.
    • This technique offers a novel way to control nanoparticle assembly and optical properties.
