Facile green synthesis and characterisation of gold nanoparticles using fenugreek seeds and honey

Abstract

Gold nanoparticles are frequently employed in a range of biological applications because of its versatility in biosynthetic pathways and complexation, good biocompatibility and ease of detection. This study discusses the application of green chemistry in the production of gold nanoparticles using fenugreek and honey. It discusses nanoparticle characterisation in order to investigate structural, morphological, and optical characteristics. The mean crystalline size of fenugreek-mediated gold nanoparticles is 12.035nm nm, while honey-mediated gold nanoparticles are almost 42.2225 nm, according to XRD analysis. The absorption and fluorescence spectra correlated well with particle size variance in that the absorption and fluorescence peak positions were observed to move as particle size increased. The spherical shape of the particles was shown by SEM and TEM analysis, and the particle size was confirmed by XRD. EDAX analysis demonstrated the sample's purity. On the surface of the sample, the presence of a functional group with distinctive peaks of gold NPs is shown by FT-IR and FT-Raman analysis, indicating a high potential for hyperthermia treatment, biomarkers, and cancer diagnostics.
