TEM is
used
to
see
the
fine
structure
of
cells.
Ultra-thin
sections
of
the
object
are
prepared,
by
embedding
or
freezing
the
specimen
and
sectioning
it
with
a
diamond
or
glass
knife.
Sections
are
floated
in
water
and
picked
up
on
a
wire
grid.
They
are
stained
with
a
heavy
metal
(gold
or
palladium)
to
make
certain
part
dense,
and
inserted
in
the
vacuum
chamber
of
the
microscope.
