Many nanomaterials, including gold nanoparticles (AuNPs) [7, 19], carbon nanotubes (CNTs) [21], iron oxide nanoparticles [22], and grapheme oxides (GOs) [23], have been developed for use in PTT.
Many biotherapeutic applications of gold nanoparticles make use of conjugated or adsorbed protein moieties.
Many biomedical applications of gold nanoparticles (NPs) rely on proteins that are covalently attached or adsorbed on the NP surface.
For preparation of gold nanoparticles, many different reducing agents and stabilizing compounds have been employed to control shape and size of the particles.
In recent years, with the rapid development of nanoscience and nanotechnology, many nanomedicines, such as gold nanoparticles, metallic multi-segments, silicon nanowire, iron core-gold shell nanoparticles, chitosan nanoparticles, and gold nanorods, have been designed for tumor therapy.
There have been many medical applications based on gold nanoparticles (GNPs) over the past several centuries.
Nanotechnology is an emerging discipline of sciences, and gold nanoparticles have many potential applications.
Many studies prove that the gold nanoparticles of 30 50 nm range show good anti-cancer effect.
To improve LFIA sensitivity, many efforts were reported, including gold nanoparticles loaded with enzymes [22], a dual gold nanoparticle antibody conjugate [23], enlargement of immunogold particles [24], and triple lines gold nanoparticle-based LFIA [25].
The unique physical properties of gold nanoparticles render many applications in cancer treatment, such as radiosensitizers, and agents for photodynamic therapy or photothermal therapy (Dykman and Khlebtsov 2012; Zhang 2015).
