Green synthesis of gold nanoparticles (GNPs) has received substantial attention, because nanoparticles are produced in an eco‐friendly way using biomolecules present in plant extracts in a single step reaction. This research article highlights GNPs obtained using shade‐dried leaf extracts of Millettia pinnata (L.) with aqueous auric chloride (HAuCl 4 ) at ambient temperature. In the present study, GNPs with average particle size 37 nm in size were fabricated. Furthermore, the synthesis method to obtain stable and monodispersed GNPs was advanced by optimising enzyme concentration 100 μg/ml, pH 5.4, substrate concentration 0.45 mM and 12 h time of reaction. The confirmation of GNPs formation and characterisation was followed by UV‐vis‐absorption spectroscopy, dynamic light scattering (DLS), and zeta potential (ZP) for the analysis of shape, size, and stability, respectively. TEM images and powder XRD revealed the GNPs synthesis of spherical‐shaped nanoparticles in the face‐centred cubic arrangement. Cytotoxicity of GNPs was studied against A549 lung cancer cells with IC 50 14.76 μg/ml and found lower as compared to doxorubicin IC 50 11.23 μg/ml but significant enough to be used as a vehicle GNPs produced using green source can be used as significant therapeutic agents and drug delivery carriers.
