Abstract
We present a simple and inexpensive method for the capture and
release of bacteria contained in an array of conical nanopores on
a membrane inside a microfluidic device. As an example, we
demonstrate that cyanobacteria can be captured, one bacterium per
pore, in a defined orientation with over 500 bacteria per membrane
with viabilities as high as 100%. The device can also specifically
capture cyanobacteria from a mixed suspension of cyanobacteria
and chlamydomonas with a selectivity as high as 90%.
