Conductive oxygen barrier films using supramolecular assembly of graphene embedded polyelectrolyte multilayers.

The supramolecular self-assembly of polyelectrolyte multilayers (PEMs) provides robust bottom-up strategies to assemble a broad spectrum of nanostructures on the host substrates. In this study, we discuss the formation of graphene nanoplatelet (GNP) embedded polyelectrolyte films to enhance the oxygen barrier properties of poly(ethylene terephthalate) (PET) films. Despite cheaper costs and high mechanical strength, the diffusion of small gas molecules such as oxygen through PET films remains a matter of great concern.

Innate immune mechanism in allergic asthma.

Allergic asthma is a chronic inflammatory disorder of the airways characterized by eosinophilic inflammation, airway hyperresponsiveness, and mucus hypersecretion. Adaptive, antigen-dependent immunity is critical for asthma pathogenesis. Allergic asthma may involve adaptive and innate, antigen-independent immune responses.
