Fabrication of microfluidics structures on different glasses by simplified imprinting technique

Imprinting technique is an efficient method for fabricating microstructures for microfluidics and lab-on-chip applications. However such technique is not commonly used for glass based microstructures fabrication. In this study, microstructures were transferred completely and successfully from a nickel alloy stamp to different glasses such as sodalime glass, Pyrex glass, SGBN glass and magneto optical glasses, using imprinting technique. Furthermore, the traditional vacuum hot press for imprinting was replaced with the conventional electric furnace which increases the cost efficiency and simplicity greatly. Using specific mold in the conventional furnace, the mass production of microstructured glass chips can be realized.

► The method (imprinting) in this paper is simple and low cost for fabrication of microfluidics structures on glasses compared to photolithography.
► Microfluidics structures were fabricated on different glasses.
► Conventional furnace was used which simplified the conventional imprinting.
►  Mass production in conventional furnace for microfluidics chips on different glasses is possible and proposed.
