Flash μ-Fluidics: A Rapid Prototyping Method For Fabricating Microfluidic Devicess

详细技术说明

Fabrication of a lab on a chip final product can be done in just one step. A digital light projector (DLP) can be used as a maskless lithography system. The channels can be fabricated within 2 – 20 seconds. At a specific distance the projected light from the DLP can be focused on at least one of the surfaces or substrates that is transparent to light. The light can solidify (cure) selected sections or portions of the light sensitive material between the two surfaces to form the microfluidic channels.

*Abstract

Microfluidics has advanced in terms of designs and structures, however, fabrication methods are either time consuming or expensive to produce, in terms of the facilities and equipment needed. A fast and economically viable method is provided to allow, for example, research groups to have access to microfluidic fabrication. Unlike most fabrication methods, a method is provided to fabricate a microfluidic device in one step. A resolution of 50 micrometers was achieved by using maskless highresolution digital light projection (MDLP). Bonding and channel fabrication of complex or simple structures can be rapidly incorporated to fabricate the microfluidic devices.
