The
patent pending SideConnect technology simplifies the microfluidic
chip/cartridge design. Microfluidic access is provided on the edge of the chip
at the bonding interface between top and bottom wafer (side connection), thus
avoiding additional processing like hole drilling or powder blasting of the top
layer. This reduces production costs. Moreover, the functional area of a chip
can be significantly reduced due to the smaller footprint of the design (only
channels). The microfluidic chip can be side connected to a plastic cartridge
either in a 2D (in-plane) or a 3D (out-of-plane) configuration.
The
2D version results in a slim assembly, which is easily accessible for optical
applications.
The
3D version contains top reservoirs that can be easily integrated into a
surrounding cartridge and accessed for pipetting a defined volume of sample,
buffer or reagent.
This
SideConnect technology has already proven to be compatible with applications
like capillary electrophoresis, but the chip-cartridge design can basically be
customized to any specific application. Currently, new SideConnect disposable
lab-on-chip products are being developed for use in several Point-of-Care
applications.
