A cost-effective and energy-saving approach to prepare microfibrillated cellulose (MFC) nanocomposites from natural wood fibers is reported. The MFC was mixed with calcium peroxide (CPO) or without catalase form multilayered that allow modulation of the releases hydrogen (H2O2) oxygen (O2), respectively. release profile H2O2 up five days obtained, effects O2 on responses mammalian cells were evaluated. results showed itself possesses great biocompatibility, MFC/CPO are able suppress cell...

Polystyrene, a polymer extensively used in the biomedical field, causes problem for some applications because of its surface hydrophobicity. Nitrogen plasma could transform this shortage through polar group attachment. To understand role hydrogen during functionalization nitrogen cold plasma, effects and mixture N2/H2 are investigated by both examinations densities attached amine groups in-situ diagnostic analyses such as optical emission spectroscopy mass spectrometry. An increase has been...

Abstract The choice of plasma gas can determine the interaction between material and therefore applications treated materials. Nitrogen integrate functional groups such as primary amines carbon dioxide incorporate carboxylic on surface polymers. For specific adhesion bio‐adhesion, polar must be attached to enhance bio‐film formation but acidic or basic character also controls mechanism. plasmas are chosen treat polystyrene show effects different functionalizations, i.e. attachment acid...
