In the realm of nanomaterials, atomically precise quasi-molecular gold nanoclusters (AuNCs) play a prime role due to their unique, stable, and highly tunable optical properties. They are extensively structure-engineered for modulation surface electronic states toward long wavelength photoluminescence, particularly in NIR-II (1000 1700 nm) window. Contrast agents with emission can potentially transform imaging terms higher spatial resolution, deeper tissue penetration, reduced autofluorescence. These advantages allow real-time living organisms observing disease progression treatment response. this short review, we discuss origin rationally designed AuNCs application high resolution vasculatures hard soft structures identification pathological conditions such as stroke injury.

The influence of gold nanocluster–solvent interactions on nanostructure optical properties was determined. Using [Au11(BINAP)4X2]+, where X = Cl or Br, as a model system, the dramatic halogen–solvent hydrogen bonding nanocluster resolved. creation hydrogen-bond network yielded intense photoluminescence (PL) and an accompanying 2-fold reduction in vibration-mediated nonradiative decay rates. PL quenched for systems that did not support bonding. As reflected by absorption line widths, Raman scattering, transient spectroscopy measurements, increased structural rigidity reduced carrier results highlight significant role interface determining structurally precise materials.
