A Company Dedicated to Providing Custom Microfluidic Solutions For Your Needs
The Lego® Sandwich PlatformThe Lego®-sandwich microfluidic platform is an inexpensive method to produce microfluidic devices without the use of adhesives or laborious fabrication techniques. To make a Lego®-sandwich assembly, optically transparent acrylic sheets are etched with a CO2 laser machine to create microfluidic features and to cut alignment holes. The shape of the acrylic layer is specially designed to fit onto the Lego® plate which forces the feature-containing acrylic layer against a thin PDMS layer on the Lego® plate. This PDMS layer and interference fit of the acrylic layer is designed to provide sufficient sealing that contains the fluids being investigated. With the design of the channels made ahead of time, fabrication time for the initial design was less than ten minutes.
AdvantagesCompared with traditional microfluidic fabrication methods, our device would have several advantages- Highly customizable- Easy to use and setup- Reversible bonding [4]- Allows for reuse and thorough cleaning- Cell studies-Surface treatment- Quick turn around time to produce- Low cost production methods could allow for custom design fabrication- Due to the method of fabrication low volume production, such as in design development, would be economically feasible.
