Some nanotechnology production techniques require
incredible amounts of time and expertise to accomplish.
In contrast, PEBBLE production is rooted in basic
chemistry methods which in principle are not more
complicated than a freshman lab procedure. Of course, we
do a lot of work investigating little changes in
contents and techniques which make a big difference in
the end as far as how well the sensors work in different
applications. But, the basic technology is quite cheap,
easy and fast.
The example shown here is used for polyacrylamide
PEBBLEs. Water in oil microemulsions are used for the
synthesis, then the PEBBLEs are concentrated and washed
in Amicon tangential filtration systems and vacuum
filters. Dry powder can be stored for a very long time
before resuspension and use for sensor work.
