Abstract
A microfluidic device molded in a single step provides a seamless fluid communication path from fluid input features to microfluidic channels. The device comprises a molded material which is formed around thread for forming high aspect ratio microfluidic channels. An associated method for the manufacture of the device is also provided.
Claims7
A method of manufacturing a single step molded microfluidic device, generally comprising the steps of:
- a. providing a molding material suitable for the molding of a microfluidic device;
- b. preparing the molding material prior to curing;
- c. providing a mold having at least one fluid input and more than one thread for forming microfluidic channels, at least one of which is in fluidic communication;
- d. optionally modifying the surface energy of at least one thread;
- e. introducing the molding material to the mold;
- f. at least partially curing the molded material;
- g. separating the at least partially cured molded material from the mold.
