Time-point-based analysis of gold nanoparticles in MCF-7 cells following ultrasound irradiation: quantitative and label-free intracellular characterization

Key Points

• This research investigates the behavior of gold nanoparticles in MCF-7 cells under ultrasound irradiation at different time points.
• Characterization of gold nanoparticle behavior in MCF-7 cells after exposure to ultrasound.
• Quantitative assessment of intracellular diffusion and accumulation effects based on recovery time.
• Label-free analysis technique employed for measuring nanoparticle presence.
• Gold nanoparticles diffuse and accumulate significantly in MCF-7 cells when subjected to ultrasound irradiation.
• The extent of accumulation varies across different recovery time points, indicating time-dependent behavior.
