Nanoparticles of gold that for years have been recognized are the concept of an increasingly rising reports number and of promising for electronic, optical, magnetic, biomedical and catalytic applications in century of 21st. Because of Nanoparticles of gold stability, an interest in such research is a reason for performing the current work. There are various types of AuNPs: Zero-dimensional AuNps: quantum dots, spherical nanoparticles. AuNPs as 1-dimensional: nanowires, nano-rods, nano-belts, nanotubes. AuNPs as2-dimensional: nano-plates of gold, nano-shell and, AuNPs as 3 dimensional: nano tadpoles of gold, nano- dumbbells of gold (AuNDs), AuNPs being spread, for example, nano-dendrites of gold, nano-pods, and nano-stars. Au NPs, in the field of medicine are investigated for several applications include vectors of drug delivery, agents of contrast, and therapy of localized heat, biomarkers of ultra-sensitive and more. AuNPs are very attractive material for biosensor, chemosensory, genosensor and immunosensor production
