1. A method to synthesize a silver nanohybrid material, comprising:
mixing a silver nitrate solution with a citrate solution to form silver nanoparticles (AgNPs);
esterifying a first mixture comprising octadecanoic acid, octadec-9-enoic acid, and octadeca-9,12-dienoic acid with caffeic acid in the presence of an acid catalyst and a solvent to form an unsaturated carboxylic acid mixture comprising first, second, and third acrylic acid derivatives;
reacting the unsaturated carboxylic acid mixture with ethylene glycol to form a second mixture comprising first, second, and third ester derivatives;
mixing the silver nanoparticles with the second mixture to form a third mixture; and
evaporating water from the third mixture to form the silver nanohybrid material, wherein the silver nanohybrid material comprises a silver nanoparticle core covered with the first, second, and third ester derivatives bonded to the silver nanoparticle core by hydrophobic tails of the first, second, and third ester derivatives.
