A growing body of research highlights the potential of plant-mediated synthesis for producing gold nanoparticles (AuNPs) in an environmentally friendly manner. However, a knowledge gap exists regarding the comparative effectiveness of different plant parts in facilitating this process. This study addresses this gap by investigating the AuNP synthesis potential of C. guianensis leaf, fruit, and flower extracts. Our results show that these extracts can be successfully utilized for the rapid, one-pot synthesis of AuNPs with controlled size and morphology. A comprehensive characterization of the synthesized AuNPs was performed using a range of analytical techniques, including UV-vis spectroscopy, FESEM, DLS, XRD, and FTIR analysis. Furthermore, the antimicrobial activity of the synthesized AuNPs was evaluated, revealing a minimum inhibition concentration (MIC) of 0.048 mM against Gram-negative bacteria (E. coli).
