Gold Nanostructures in Biomedical Technology

Gold Nanostructures in Biomedical Technology

Nanomaterials have been defined as any material possessing at least one dimension in the nanometer scale between 1 and 100 nm. As a result, a new field has emerged during last decades: Nanotechnology. It can be defined as the design, synthesis and application of materials and devices whose size and shape have been engineered at the nanoscale. In addition to the main properties of Nanomaterials,...

Gold nanostructures: a class of multifunctional materials for biomedical applications.

Gold nanostructures have proven to be a versatile platform for a broad range of biomedical applications, with potential use in numerous areas including: diagnostics and sensing, in vitro and in vivo imaging, and therapeutic techniques. These applications are possible because of the highly favorable properties of gold nanostructures, many of which can be tailored for specific applications. In th...

Gold nanostructures: engineering their plasmonic properties for biomedical applications.

The surface plasmon resonance peaks of gold nanostructures can be tuned from the visible to the near infrared region by controlling the shape and structure (solid vs. hollow). In this tutorial review we highlight this concept by comparing four typical examples: nanospheres, nanorods, nanoshells, and nanocages. A combination of this optical tunability with the inertness of gold makes gold nanost...

Titanium nanostructures for biomedical applications.

Titanium and titanium alloys exhibit a unique combination of strength and biocompatibility, which enables their use in medical applications and accounts for their extensive use as implant materials in the last 50 years. Currently, a large amount of research is being carried out in order to determine the optimal surface topography for use in bioapplications, and thus the emphasis is on nanotechn...
