Gold Nanoprisms: Synthetic Approaches for Mastering Plasmonic Properties and Implications for Biomedical Applications

Abstract: In a comprehensive approach to the preparation of gold nanoprisms (AuNPRs), we first discuss three developed synthetic strategies to produce 2D planar-twinned morphologies with plasmonic control for practical applications. The developed synthetic procedures do not employ cytotoxic reagents, e.g., cetyltrimethylammonium bromide, and no shape purification is required. The primary synthesis of AuNPRs is based on iodide (or triiodide) redox mediation that enables shape selection with >99% yield. Another synthetic … Show more

“…It is noteworthy to mention that the reductions with ascorbic acid and hydroquinone under identical growth reaction conditions with 9 mM Met and 300 μM Au 3+ show ζ potential values of −4.6 and −15.5 mV, respectively. Hydroxylamine-based growth reactions in the presence of 9 mM Met and a 300 μM Au 3+ salt with other nanoshapes such as gold nanorods 43 (ζ potential = −46.0 mV) and nanoprisms 44 (ζ potential = −16.2 mV) result in ζ potential values of +19.2 and +13.9 mV, respectively.…”

“…Several important questions regarding the study of colloidal nanoparticles still need to be explored . Recently, gold nanoparticles in the shape of platelets were also discussed for biomedical application, so a study of high-aspect-ratio nanoparticles and particles can be investigated in the fields of biomedical applications. A recent study discloses an important role of the orientation force to describe the functioning of the structure …”

“…In nanoscience research, anisotropic nanoparticles (NPs) are particularly attractive owing to their extraordinary optical, electronic and catalytic properties 1 5 . In 2001, Mirkin and coworkers first reported a bulk solution phase synthesis of Ag nanoprisms and identified quadrupole plasmon resonances 6 .…”

“…In preparing anisotropic NPs, the early-stage seeds are often critical but remain difficult to study such ultrasmall seeds (typically up to a few nm in size) 2 , 5 , 6 . In recent research, atomically precise metal nanoclusters (NCs) of 1–3 nm in diameter (e.g., stabilized by thiolates (SR) or other ligands) have emerged as a new class of nanomaterials, which can serve as models to relate the detailed structures to the assembly and various properties 21 28 , but no relationship between the anisotropic NPs and NCs has been discussed in the literature.…”
