Biophiltre uses Nano-Technology
to make Portable Kidney Dialysis
September 11, 2005
Kidney failure may have a new
treatment soon with newly emerging nano-technology. A nano-technology
startup company called Biophiltre is developing a filter that will copy
the functions of the kidney.
The artificial device would be made
up of 2 membranes; one call the G would copy the function of the
glomerulus, the other is called the T, which will mimic the renal
tubule. The glomerulus is the part of the kidney that filters the blood
leaving water as a byproduct. The Renal tubule function is to a
recycling center to reclaim compounds that need to be reused.
"Nanotechnology permits us to design
each pore to selectively reclaim chemicals based on their size, shape
and charge," explained Nissenson who is directory of the University of
California at Los Angeles Medical Center’s dialysis services and also is
helping to organize Biophiltre's scientific board.
The conventional dialysis machine
makes it almost impossible for portability because of the way it works.
The new technology will allow for the person to bring it along with them
and have longer times to clean the blood.
The results of one test for the
device on a computer ran over a 12 hour period was able to provide
double the filtration compared to regular dialysis machines. The first
device will be around 3-4 pounds with the battery weighing in at 3 ½
pounds. The battery can run for 8 – 12 hours at a time. In the future
they hope for a device the size of a large watch.
One thing that the device will not do is recycle the
bicarbonate, so patients will still be subject to taking bicarbonate
tablets or fluid in order to maintain acidity levels
