Lab on a chip.docx
- 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.
