Gold nanoparticles (AuNPs) represent a novel nanomaterials applied in various nanotechnology fieldsbecause of their special optical properties. Gold nanoparticles strongly absorb visible light and can bequickly converted into heat, which is used in photothermal. On the other hand, folic acid and folate can beused for selective targeting of nanoparticles towards cancer cells.We report here the some geometrical properties of a new nanoconjugate made up of folate and goldnanoparticle (AuNP) and conjugated by 4-aminothiophenol (4Atp) linker, named Folate-4Atp-AuNP andapplied for the selective cancer cells targeting and destruction. we conclude that Folate-4Atp-AuNP is usefulfor cancer therapy.In this report, the Molecular Structure, and some Geometrical properties (Bond lengths and Bond angles)Folate-4Atp-AuNP were investigated using the Density Functional Theory (DFT) calculations.
