General description

Gold evaporation slugs are chiefly employed in decorating nanoparticles which possess unique characteristics such as plasmon resonance and catalytic effects.

Application

  • Gold nanoparticles in diagnostics and therapeutics for human cancer: Discusses the bio-applications of gold nanoparticles, particularly in cancer diagnostics and therapy, highlighting their low immunogenicity and potential for targeted drug delivery (Singh et al., 2018).
  • Chemical and physical heterogeneity within native gold: This study provides insights into the heterogeneity of gold and its implications for various scientific studies, which is crucial for understanding gold′s physical and chemical properties in natural settings (Chapman et al., 2021).
  • Gold nanoparticles for biology and medicine: Provides a comprehensive overview of the utilization of gold nanoparticles in biological and medical applications, emphasizing their unique properties that benefit drug delivery systems and therapeutic agents (Giljohann et al., 2015).
  • Surface plasmon resonance in gold nanoparticles: A detailed review focusing on the surface plasmon resonance properties of gold nanoparticles and their applications in sensing, imaging, and other technologies (Amendola et al., 2017).
