Claim Text:
1. An encapsulation barrier stack for encapsulating at least one of a moisture and oxygen sensitive article, comprising: a multilayer film to be arranged on a substrate, the multilayer film having at least one barrier layer having at least one of low moisture and low oxygen permeability, and at least one sealing layer arranged to be in contact with a surface of the at least one barrier layer, for plugging at least one defect present in the barrier layer, wherein the at least one sealing layer comprises reactive nanoparticles interacting by way of chemical reaction with at least one of moisture and oxygen to retard the permeation of the at least one of moisture and oxygen through the at least one defect present in the barrier layer, wherein the nanoparticles present in the at least one sealing layer plug the at least one defect present in the at least one barrier layer, wherein the nanoparticles have different at least one of shapes and sizes for controlling the sealing and plugging of the at least one defect, wherein the barrier layer comprises a material selected from indium tin oxide (ITO), TiAlN, SiO
