All About Microgold Gold Nanoparticles

Definition, Properties and Applications

Microgold, also known as microelongated gold particles, refers to gold particles with a particle size ranging from 0.001 to 0.020 mm Li et al. (2021). These particles have garnered significant interest due to their unique properties and potential applications in various fields. The directed assembly of hybrid nanomaterials and nanocomposites has been explored, demonstrating the assembly of chains of dimers of colloidal particles and colloidal rod-like "microgold" particles localized by topological defects in liquid crystals (Zhang et al., 2018). Additionally, microgold has been utilized in gene delivery into plant cells for recombinant protein production, where the transgene is coated onto microgold particles and fired into plant cells ballistically (Chen & Lai, 2015). Furthermore, microgold has been employed in biolistics, also known as 'particle bombardment', where particles coated with DNA are used to deliver transgenes directly into diatom cells (Γρυπιώτη, n.d.).

The coupling of the optically active protein PS I to the microgold antenna localized surface plasmon resonances (LSPRs) has shown potential for novel breakthrough applications, such as the potential of this hybrid biosolid state active platform to act as a Bolean logic gate for the fast control of optical output signals from the plasmonic antenna in optic communication systems (Carmeli et al., 2023). Moreover, microgold has been used in virus host jumping studies, where microcarrier cartridges were prepared with 1.0 μm gold particles coated at a DNA loading ratio and a microcarrier loading amount (Martínez-Turiño et al., 2021).

In summary, microgold, with its unique properties and diverse applications, has been utilized in various fields, including nanomaterial assembly, gene delivery, biolistics, and hybrid biosolid state active platforms. Its potential for novel breakthrough applications makes it an area of active research and exploration.
