abstract = {A simple lab-on-a-chip method for blood plasma separation
was developed by combining stereolithographic 3D printing
with inkjet printing, creating a completely sealed
microfluidic device. In some approaches, one dilutes the
blood sample before separation, reducing the concentration
of a target analyte and increasing a contamination risk. In
this work, a single drop (8 μl) of heparinized whole
blood could be efficiently filtered using a capillary effect
without any external driving forces and without dilution.
The blood storage in heparin tubes during 24 h at 4 °C
initiated the formation of small crystals that formed
auto-filtration structures in the sample upon entering the
3D-printed device, with pores smaller than the red blood
cells, separating plasma from the cellular content. The
total filtration process took less than 10 s. The
presented printed plasma filtration microfluidics fabricated
with a rapid prototyping approach is a miniaturized, fast
and easy-to-operate device that can be integrated into
healthcare/portable systems for point-of-care diagnostics.},
