Abstract
A method of manufacturing a microfluidic device having at least one cylindrical microchannel includes providing a substrate, casting an uncured polymer matrix solution onto the substrate, embedding an elongated rod in the uncured polymer matrix solution, curing the polymer matrix solution to form a solidified body, and extracting the elongated rod to form the cylindrical microchannel in the solidified body. In another embodiment, the method includes forming an optical feature on a surface of the microfluidic device. A microfluidic device is also provided, the device including a polymer body, and at least one cylindrical microchannel in the polymer body, the cylindrical microchannel having a diameter between approximately 40 ?m and 250 ?m, inclusive. An additional microfluidic device is provided that functions as an optofluidic spectrometer. The optofluidic spectrometer includes a polymer body, a diffraction grating integrated within the polymer body, and a cylindrical microchannel behind the diffraction grating on the polymer body.
