Banana
peels are mainly composed of pectin, cellulose and hemicelluloses
(Emaga et al., 2007) and the functional groups
associated with these polymers as well as the proteinaceous matter may thus be involved in reducing the Agþ to Ag0. Biological
components are known to interact with metal salts via
these functional groups and mediate their reduction to
nanoparticles (Bar et al., 2009).
