1) The seminar discussed the use of nanomaterials like vanadium oxide nanowires and tellurium fibers for applications such as batteries and preventing mold. 2) Vanadium oxide nanowires can be grown on silicon substrates and have potential uses in battery architectures. Tellurium fibers can create superhydrophobic surfaces useful for preventing mold. 3) For a lab-on-a-chip that mimics an entire lab, a pump would be needed to circulate fluids, but it must be small enough for the chip. Pressure pumps may be too slow, so other options like electrokinetic or electrodynamic pumps were discussed.

1. Lab on a chip: Seminar
Nanotechnology can be an useful tool to explore in the patophysiology of disease that the human
race encourage every day. First of all we have to establish what is nano material? A nano
material is something that should measure at least 10-9 meters. In the seminar and workshop that
provided Jesus Velazquez and Ivonne Ferrer, they mention that all this nano materials can have
an important application for the solution of problems in the real lfe. We encourage problems
related with the natural resources, energy and diseases. Velazquez explains the nano materials
important utilities that have in this days. He explained to us the topic of his research that was
about an arrays that are composed by Vanadium Oxide (V2O5). This nano wires are grown on
silicon substrates by a catalytic growth processor (catalytic vapor-solid mechanism). The
nanowires that emerge of this process are oriented by the substrate coverage, that in this case is
Silicon, Some factors that you have to control the growth of the nanowire or the nano material
are: the duration of the reaction, the temperature of the reaction and the flow felicity of the
Vanadium Oxide. These emerged nanowires have applications like: using it in the fabrication of
novel battery architectures. Basically, the researcher used a mold or a template. Then he
deposited the polymer that he is using to cover the wire and the he dissolved the polymer if he
wants. The polymer is dissolve of the surface depending of the application that you will be
applying to that emerging nano material. In addition with this technique you can also do a super
hydrophobic material based in tellurium. The tellurium divides in little fibers that are super
hydrophobic. This has a very important application to avoid a real problem: the mold. This super
hydrophobic should avoid the mold in every material. This entire theory was developed from the
techniques of the geckos. Then Ms Ferrer talk to us about the pump that we should use if we
create a nano material that can represent an entire laboratory on a single chip should have a
pump that imitate the work of the heart to circulate the blood in the chip. That’s because Ms
Ferrer is researching about the type of pump that we can use in the chip. This pump should have
a source of energy but because we are talking of something that is very small we have to think in
everything. There are some types of pump like the pressure pump that is a problem because may
be can represent a too slow flow rate.
Also we should mention that in the paper we have the term of Electro kinetics and
Electrodynamics because in the paper the researcher says that in a single chip we should discover
is a new drug can be useful to humans without using a clinical trial.
