Method of fabricating microfluidic structures for biomedical applications
First Claim
1. A method for fabricating a microfluidic structure, comprising:
- (a) providing a patterned wafer comprising at least one exposed electrically conductive region and at least one exposed electrically insulating region;
(b) electroplating an inverse channel portion with substantially semicircular cross section onto the wafer, thereby forming a first master mold;
(c) employing the first master mold so as to emboss a channel portion in a first polymer sheet;
(d) aligning and bonding the first polymer sheet with a second polymer sheet having a corresponding channel portion such as to define a first channel with substantially circular cross section between the polymer sheets.

Abstract
Methods of fabricating microfluidic structures featuring substantially circular channels are provided. The methods involve (a) providing a patterned wafer comprising at least one exposed electrically conductive region and at least one exposed electrically insulating region; (b) electroplating an inverse channel portion with substantially semicircular cross section onto the wafer, thereby forming a first master mold; (c) employing the first master mold so as to emboss a channel portion in a first polymer sheet; and (d) aligning and bonding the first polymer sheet with a second polymer sheet having a corresponding channel portion such as to define a first channel with substantially circular cross section between the polymer sheets.
