Microfluidics and
Microfabrication
Miniaturizing chemical, biological, and medical
devices and systems has many advantages, including the use of
small sample and reagent volumes, system portability, and
disposability. Although microfabrication of microfluidic
devices is highly developed, there are still certain
limitations. For some applications, truly 3 dimensional
structures are desired, especially those that possess
arbitrary surface height profiles. Realization of such
structures generally requires multiple lithographic masking
and etching, alignment and bonding steps, which add
significant process complexity and impact reproducibility and
yield.
MicroDysis has
developed 3
Dimensional Micromolding microfabrication
technology to overcome these deficiencies, which eliminates
the bonding procedure in traditional and other
microfabrication methods.
Main advantages
of 3
Dimensional Micromolding
are:
- No fluidic
Leakage
- Flexibility in
Design: Any aspect
ratio and shape of microstructures can be created inside a
microdevice.
- High Pressure
Tolerance: Pressure
used for microstructure flushing and loading can be much
higher than that of the bonded device.
- Lower
Cost: Materials
used in this approach are less expensive than glass, silica,
and quartz that are used in other fabrications, which
decrease the cost of the microdevice.
- Ease of
Integration: The
technology eases embedding elements with fluidic channels
and chambers for the integration of electronics,
optics, fluidics, and their interfacesin the device,
and facilitating the development of lab-on-a-chip
device.
