Thermal nanoimprint lithography of sodium hyaluronate solutions with gas permeable inorganic hybrid mold for cosmetic and pharmaceutical applications

Abstract

Abstract Gas-permeable inorganic hybrid mold that hybridized the surface layer of TiO2–SiO2 gas-permeable polymer using the sol–gel method and the lower layer of porous maraging steel by a metal three-dimensional printer was developed for fluid function materials containing high concentrations of water and volatile solvents. Thermal nanoimprint lithography was used to fabricate the advanced high-resolution needle patterning of sodium hyaluronate containing volatile solvents to broaden the application area of fluid function materials such as cosmetics and pharmaceuticals.
