Gold in polyaniline: Recent trends

Nanotechnology offers an extremely broad range of potential applications in, for example, electronics, optical communication and biological systems. Gold nanoparticles of different sizes and shapes combined with polyaniline can give rise to a host polymer with interesting physical properties and important potential applications. Many possible applications for this system have been explored, many devices and systems have been studied, while more potential applications and devices are being proposed. Such composites are discussed in this review on the basis of the techniques used for their synthesis, their properties and possible applications.
