Today, it is a little more technical post, but it will help you understand more about our
#research.
Well, it's simple, we use
#ion beam micro-lithography.
All clear, right??
Not clear enough?
Okay, let's start over.
#Diamond ? (the material of precious gems) and
#graphite
(the material they write pencils with) are both made of carbon atoms
but bonded differently, which gives these two materials unique
properties.
In our
#lab,
we convert diamonds into graphite using a beam of ions.
This beam of
electrically charged atoms induces local damages to the structure of the
diamond, starting the
#graphitization
process.
In simple terms, you can think of the ion beam as a pen ✏ capable of
"drawing" small graphitic tracks on the diamond.
But why are we so crazy about turning a diamond into something like a
pencil lead ??
The answer lies in graphite being electrically conductive, allowing it
to record electrical and chemical signals released by cells?.
To come to the point, our biosensor is nothing more than a combination
of diamond and graphite properties. Solid and biocompatible properties
of diamond for growing on it the cell to be studied, and the graphite
electrical properties to be able to "listen" to the cells.
