It is crucial to a wide array of industries, with various important utilities in modern life. Microfluidic devices can improve the quality of emulsions by controlling the droplet size formed. PMMA, poly(methyl methacrylate) has low material cost, and is often used as a lightweight, shatter-resistant alternative to glass. Methods such as micro-injection molding can be used in making PMMA microfluidic substrates with open micro-channels.

In this project, the effectiveness of tape bonding on PMMA microfluidic substrate was tested with air, water and oil.

description Microfluidics and microfluidic droplet technique is a hot topic of study in the recent years. It is crucial to a wide array of industries, with various important utilities in modern life. Microfluidic devices can improve the quality of emulsions by controlling the droplet size formed. PMMA, poly(methyl methacrylate) has low material cost, and is often used as a lightweight, shatter-resistant alternative to glass. Methods such as micro-injection molding can be used in making PMMA microfluidic substrates with open micro-channels. These micro-channels need to be sealed before the microfluidic device is rendered usable. Various bonding methods, such as bonding with heat, where plastic molecules are fused together, and bonding without heat, where adhesive and chemical solvents are used, are employed to seal the micro-channels.
