Polymeric nanocapsules containing eugenol were used to protect nectarines from brown rot caused by the fungus Monilinia fructicola. The formulation with chitosan was the most effective, increasing the probability of fruits remaining healthy even after 7 days, making it an alternative for post-harvest applications. Details are presented in the Article Nectarine Coated with Biopolymeric Nanocapsules Containing Eugenol to Control Brown Rot by Joslaine Jacumazo, Gabriela P. Parchen, Meira J. B. Garcia, Nayana C. S. Santos, Louise L. M. De Mio, Francisco A. Marques and Rilton A. de Freitas on page 1030.

How to cite this article

 

Biogenic silver nanoparticles are synthesized through silver(I) reduction promoted by biomolecules. The one-pot biosynthetic process leads to stable silver nanoparticle (AgNP) colloids with surfaces capped by some of the biomolecules that also took part in their synthesis.
