Nanoparticles





Science advances day by day in all areas and at all scales, and I think that choosing an application of nanoscience is quite complicated. If I am sincere, I have informed myself a little about it since listening to microparticles makes me immediately think of a more biologist area and those who know me know that my interest in biology is null.

Therefore, and considering that my career does not have a biologist approach, before writing this publication I decided to look for some information and I found really wonderful things that have a great significance in one of the areas that Chemistry focuses on.

In the energy field, nanoscience can be used in the production of renewable energies. For example, reduce the costs and in order to enhance of obtaining solar energy with photovoltaic cells, it is possible to use nanoparticles absorbing sunlight, or in obtaining hydraulic energy, seawater corrosion can be avoided thanks to the anti-fouling coating of the material.

Also, I am struck by the application of nanomaterials to generate environmental benefits, as there are nanoparticles such as iron that have been used to decontaminate lead water and arsenic, or copper and silver nanoparticles to eliminate the presence of the bacteria E. coli from contaminated water.

However, nanoparticles can still be harmful to humans due to their properties. Some can be found in sunscreens and by applying them form free radicals, DNA modification is possible. Or when inhaled or ingest them easily pass into the bloodstream because they are extremely mobile, being able to circulate throughout the body and interact with the cells.

And even if it has negative consequences, they have had a great beneficial impact in its different applications, and as scientists we must continue research so that nanoscience continues to advance and there is a significant change in humanity such as the cure of cancer…

    It is beautiful and unknown, it is surprising that something of such magnitude is used in sunscreens.

Since I was little I had a special fondness for the puppies I saw on the streets, where my friends, family, etc. At that time I lived in a small apartment where I could not have pets, so, I just moved to a bigger house in 2005 my parents wanted to give me a surprise and they gave me a beautiful puppy with black fur that I called Pillín. The reason for his name was because he was very playful and always hid to play to find it. Unfortunately Pillín was only a week with us, since one day we went out to play at the park with him and a truck ran him over. I was very sorry because the pet that I wanted so badly was dead, and although that void was not going to be easy, my parents decided to take another pet with us. This time it was a female, also a puppy, but she came with a trauma. They abandoned her in a rainy winter, and for every rain that fell she was very frightened. Her name was Mona, I put her that way because she found the name “Princesa” very common and for me she was un...

My Holidays💕

Well, maybe they have not been the best holidays, but I'll talk about them because very important events happened to me. It was recently, for the national holidays, when we decided to leave the whole family together, my brother, my parents and me. Due to space issues we could not take our pets😢, but they stayed taking care of the house😄. We could only leave 5 days, since my family has to go back to the daily routine and work. However, they were 5 days well enjoyed. We started our trip being Chillá n our first stop, there we went to visit my grandmother and uncle Lulu to the cemetery, then we had lunch at the Chillán market and went to my uncle Lalo's house. After our first night there, we woke up early to continue our way to Los Angeles. We went to meet a cousin of my mom who had not seen since she was 10 years old, it was a nice reunion. In addition, in the south the people are more affectionate, and we spent a beautiful day with them, we had a very t...
