“…In this method, first of all micro-emulsion of nanoparticles were prepared by using precursors such as HAuCl 4 and AgNO 3 and then reduced by NaBH 4 . After that, de-alloying was done by nitric acid [36]. Gold nanoparticles was prepared by microwave irradiation method in which aqueous extracts of Cissus quadrangularis (CQE) was used as capping agent or reducing agent [37].…”

This review is focused essentially on the synthesis and applications of gold nanoparticles in the field of medicine and targeted drug delivery. Nanotechnology has become one of the most interesting and advanced areas of research in this field. Among nanoparticles, gold nanoparticles demonstrate special advantages in this field due to their unique properties, small size and high surface area-to-volume ratio.These particles have been widely used in various biomedical applications and drug delivery systems due to their inert nature, stability, high dispersity, non-cytotoxicity and biocompatibility.

“…Calcium phosphate and silicate modified surfaces of gold nanoparticles have potential applications in orthopedic and dental reconstruction [3]. Stably dispersed gold nanoparticles that absorb near-infrared light are useful for in vivo applications because this type of light deeply penetrates the body tissues [4].…”

The study is focussed on synthesis and characterisation of a new sol-gel derived composite system consisting of nanocrystalline apatite, bioactive glass and gold nanoparticles, which are of interest both for regenerative medicine and for specific medical applications of the releasable gold nanoparticles. Samples dried at 110°C and then heat treated for 30 min at 300 and 500°C were investigated by thermal analysis (DTA/TG), X-ray diffraction (XRD), UV-VIS-NIR, Fourier Transform Infrared (FTIR) spectroscopy, X-ray Photoelectron(XPS) spectroscopy, Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). Gold nanoparticles and nanocrystalline apatite are developed already after heat treatment at 300°C. XPS analysis clearly revealed the presence of both metallic and ionic gold species. The development of gold nanoparticles was evidenced by UV-VIS-NIR and TEM analysis, and their size increased from few nanometers to 25 nm by increasing the treatment temperature from 300 to 500°C. The bioactivity of the samples immersed in simulated body fluid was demonstrated by XRD and SEM results.

“…The attraction and binding capacity of GNPs have been found to be strong with small biomolecules like carboxylic acid [21], proteins and enzymes [16], DNA and aminoacids [22]. Another important aspect of GNPs is their ability to disperse uniformly and reach the targeted site along with the blood flow [23]. They have also found to be biocompatible [24] with their overall cytotoxicity within acceptable limits [25].…”

-The unique properties of nanomaterials do enable them to contribute significantly to environmental protection; however at the same time, they also have a significant negative impact on the environment as well as on living organisms. Among the existing nanomaterials, gold nanoparticle (GNP) is quickly gaining grounds due to its wide ranging uses in the field of medicine, especially radiation therapy and targeted drug delivery. Apparently, the increased production, application and disposal of GNPs have led to an increased release of nanogold into the environment and there are very few studies that bring out the implications of such release. This study aims to review various applications of GNPs and their fate in the environment.
