TOMSK, Nov 22 – RIA Tomsk. Scientist of Tomsk Polytechnic University (TPU) Raul Rodriguez and his
colleagues from Germany and Lithuania offered how to make surface of material
suitable for cultivation and studying of living cells with graphene oxide;
technology simplifies and reduces price of dangerous microorganisms and cancer
cells studying, press service of TPU reports.
It is specified that the international group of scientists, which includes
researchers from the Vilnius University, the Center for Physical Sciences and
Technology (Lithuania), and the Chemnitz University of Technology (Germany)
besides TPU carry out the work. Results of the research are published in the
Sensors and Actuators B: Chemical magazine.
It is noted that the research of communication and interaction of cells is
important for many directions in medicine, in particular for studying of the
reasons of metastasis in oncology. The new technology allows to control
colonies of cells and to separate the cells interesting for scientists from all
others.
"Now expensive technology is used for studying of a separate cell –
so-called optical tweezers which allows to choose, move and analyze a separate
cage by means of a laser bunch. The method opened by us doesn't assume use of
the additional equipment – it is only necessary to cover any surface with
graphene oxide", – press service quotes Rodriguez.

It is added that the new technology is cheaper than the existing analogs.
It can also help with development of biosensors – flexible analytical devices
which are implanted under skin of patients and report about existence of
substances in organism for which are set up. It is necessary that their
surface was well moistened.
"We can make, in fact, any material hydrophilic (moistened – Ed.) by
means of simple technology with graphene oxide use, therefore, suitable for
creation of inexpensive biosensors", – Rodriguez explains. It is specified
that electric contacts for such biosensors are planned to be made on the
technology of "electronic tattoos" which is also developed with the
participation of TPU scientists.
