B: biological synthesis, C: chemical synthesis, A: additive, N: antagonism, S: synergy, G: gold nanoparticles, GA: gold nanoparticles with acetone extracts, GM: gold nanoparticles with methanol extracts, and GW: gold nanoparticles with water extracts. Bold values show synergistic results after the combination has been used. This can be seen by the addition of S indicating synergy.
