Gold nanoparticles (GNPs) with controlled geometrical, optical, and surface chemical properties are the subject of intensive studies and applications in biology and medicine. To date, the ever increasing diversity of published examples has included genomics and biosensorics, immunoassays and clinical chemistry, photothermolysis of cancer cells and tumors, targeted delivery of drugs and antigens, and optical bioimaging of cells and tissues with state-of-the-art nanophotonic detection systems. This critical review is focused on the application of GNP conjugates to biomedical diagnostics and analytics, photothermal and photodynamic therapies, and delivery of target molecules. Distinct from other published reviews, we present a summary of the immunological properties of GNPs. For each of the above topics, the basic principles, recent advances, and current challenges are discussed (508 references).

“…Because of this, the nanorod longitudinal axis is more polarizable and consequently the (l-LSP) is more sensitive to changes in the aspect ratio . Therefore, tuning of the (l-LSP) resonance allows enhancement of the absorption and scattering properties with significant applications in areas such as drug delivery, lateral flow assay diagnostic tests, cell imaging, and photothermal therapy for cancer and liposuction . Recent studies revealed important results, for example, in data storage, tunable random laser, and solar cell technology .…”

We investigated the nonlinear (NL) optical behavior of aqueous colloidal dispersions of rod-shaped gold nanoparticles (NPs) with different aspect ratios beyond the usual analysis of third-order nonlinearity. By applying the Z-scan technique, it was possible to observe large NL absorption, which is understood by considering the simultaneous instantaneous and thermo-optical nonlinearity contributions. In addition, light-scattering experiments were performed at high intensities, showing a significant contribution of the fifth-order scattering process that depends on the gold nanorod (Au-NR) aspect ratio. Likewise, the Z-scan measurements reveal that the quintic nonlinearity is also contributing to the refractive behavior, a feature known for spherical gold NPs but not reported for Au-NRs so far. The experimental results illustrate a nonlinearity management procedure based on the strong influence of the aspect ratio of Au-NRs in the excitation regime close to the transverse surface plasmon resonance, even keeping the nanorods’ cross-sectional diameter constant. A generalized Maxwell–Garnett model, including the intraband, interband, and hot-electron contributions, was used to clarify the origin of the nonlinearities and corroborate their dependence with the aspect ratio for the first time in the literature.
