The present invention provides a composition for increasing filtration efficiency comprising cellulose nanofiber (CNF) or a derivative thereof, an adhering agent (e.g., a polyhydroxy polymer, such as polyvinyl alcohol (PVA)), and a carrier (e.g., aqueous solvent). In various embodiments, the composition increases barrier properties against particles (e.g., aerosol particles). In some embodiments, the composition breaks a membrane of at least one cell of interest (e.g., pathogenic cell). In one aspect, the present invention provides a device comprising said composition and a material of interest (e.g., textile material). In some embodiments, the textile material is a mask, clothing, or filter. In one aspect, the present invention provides a method of increasing barrier properties of a material of interest against at least one particle using said composition.
