Silver Nanoparticles

Silver Nanoparticles

Silver Nanoparticles are incorporated in apparel, footwear, paints, wound dressings, appliances, cosmetics, and plastics for their antibacterial properties. This has been really succesfull and helpfull.
One of the things that you can do on my career it's about investigate new forms to help people to have a better life or find a solution to several desseases.
As you can see nanoparticles can be the solution as antibacterial on our common day. But also this ones can help on cancer or other desseases, but silver ones aren't the only ones finded to help people, gold and cupper nanoparticles are on prove now as well.
I chose this ones because they have been involve on breast cancer treatment and ha have a lot of success.

Breast Cancer Symbol

There's some new investigations that involve Silver Nanoparticles on Breast Cancer. This ones in the future can decrease the proliferation of cancer cells. Soon as a sphere that releases control keys silver in the middle, which are those that have the action, the proliferation start to stop.
This could be complementary to the treatments that already exist (radiations and chemotherapies), to diminish the side effects in the patients.
The results are encouraging, as the treatment with silver nanoparticles has achieved up to 80% of the cancer cells disappear.
Two years ago I learned about gold nanoparticles on a biology homework, and I got so interested that I started to look about all the nanoparticles involve on cancer treatments. That was the first time that I heard about Silver Nanoparticles.

As I had mentionated they will help to increase welfare of mans and womans hoose suffer breast cancer, making they treatment short and more succesful.

One of the advantages of using this type of nanoparticles lies in the low cost and high results. So far the tests have only been done in vitro (without living organisms) and have not yet been tested in animals. But the disadventages of using silver nanoparticles resides in the possible toxicidade of the acumulation of it, anywhere has been prove that the number of nanoparticules acumulated its little and can't damage people.

The future it's on micro and nano technology, and the future it's now. 

The Most Enjoyable Subject

One of the things that I enjoy the most it's being on the lab. This term we course the subject: " Chemical Laboratory Techniques" but I can't say this one it's my favorite subject because my favorite it's probably Molecular Genetic.

But for now, Chemical Laboratory Techniques it's going right and I like it a lot.

On this subject we learn about some basic techniques and experiments that will help us in the future to feel more confortable on the lab.

Drop by Drop we learn the precision necesary on the lab.

On the week we have lessons just one day, in my case all the thursdays. The class has a duration of 4 hours and it is divided on 2 parts. The first one it's a theory class ant it has a duration of 1 hour. The the other 3 hours are on the lab and it is a practical lesson.

Being so close to the reality of my future profession it's the reason why I like this subject so much, and the complications that can have some process that you see so short and easy makes interesting this subject, because you learn that nothing it's so fast and easy on an investigation.

The teacher in charge of the course it's Inés Ahumada, but lessons and practicals had a lot of teachers because they turn the contents and the groups to teach. 

If no one teach us it´s impossible to us know the correct way to take the instruments or the exactly precition of an experiment. Chemestry it's an exact science, so if we fail just in one drop it can be letal. We need teachers to soport and guide us to learn the correct manage of the laboratory stuff.

Biochemestry it's a career that works on the laboratory, so this subject were implicit on my desition to study a cientific investigtion career.

All students of first year has to take this subject. We are approximately 300 students, divided on groups of day and lab table.

On this term we have learn about safety rules, extraction methods,titration and about 10 contents more.

This subject it's really amazing.

Website that I enjoy visiting

A website that I use to visit frecuently it's "Investigación y Ciencia" .

Here you can find "news" about all the ciencies, so it's like read the paper news and it feels more closly to the people.

Cover done back in 2005
for Scientific American Magazine
on DNA Computing.
 

This website is the Spain edition of the Scientific American, a magazine founded in 1845 wich deliver science and technology information in a way understandable for every people, no matter the level of science background on them.

The website it's organizated by cronological news. Also has sections of magazines, news, Scilog, Subjects, and much more. It's really useful when you want to read some new information, but not with complicated words.

I used to visit this website 4 times at week when I was on school, but now I only visit it 1 or 2 times at week because I really have to study a lot.

I really like this site, because it is closly to the people, and because you can learn really too much about what is the "new" discovering of the science, but on simple words. Actually I introduced this site to my mom to read it, and she (without a good level of science background) love it, and now can understand some things that I talk on the car when I visit her. It's amazing.

My favorite Book and Film are...

I have always preferred books than other things. I love literature. I love to read and write short histories, and I also can spend a big part of my summer reading books because later they turn part of me.

The Catcher in the Rye -
J. D. Salinger

On 2015, on my school list of books for the year appeared "The Catcher in the Rye" by J. D Salinger. We read it on June. I got in love with the story and the kind of writing. This book drives me to another planet, and also makes me think about some situations of my life, turning on a spirit of auto conscient of my growing up.
What makes it attractive is that the story illustrates a teenager's dramatic struggle against death and growing up. Holden (the protagonist) tell's his own history, in his words like if he was speaking aloud to you. Holden resists to maturation.

Mark David Chapman
(If you take a look you can see
The Catcher in the Rye
between his hands)

Although, the book has something that makes some people turn on they murder spirit. The most contended case of it is the John Lennon's death by Mark David Chapman. The story says that Chapman read the book and when he ended it, he decided to kill Jhon. There's a lot of histories like this, but no one can explain what thing of this book makes some people a killer.

It's weird but I prefer books than movies, so it's difficult to me chose one movie as my favorite.
On the summer of 2016, my sister recommended me a movie. She said to me: "You will love it! It`s about a scientist". Some days later I watched it, and from this day I have watched this movie a thousand of times. It's fantastic!.
The movie is called "I Origins", and it's about a molecular biologist doctor that studies the eye. Then he falls in love with a spiritual woman that change his world.
What makes this movie fascinating its that after the death of the girl, Ian (the protagonist) uncover the possibility of the reincarnation of the souls.

Definitely, if you are a scientist, you have to watch this movie.

I recommend this ones because they connect with the soul of one of us. This book and this movie can change the way we think about the world and of our existence. Sometimes it's good to stop our hurry life and think about ourselves.

My Favorite Photograph

Me and Agustín (5 years old)

On winter of 2016, I started a new step of my life. I decided to enter on Gesta, Foundation destined to children who has not guaranteed their rights.
On winter and summer vacations, people on this foundation, is grouped around of schools with lows resources, and for a week do activities for make explicit the children rights to the boys and girls who came to find a place to play, talk, draw, run or everything they want with us.
It's beautiful to see how much love they can give to you and how much you can learn about them.

Photos of this times are my favorites, but the favorite one is a picture toked on January of 2017 by my friend Diego. I was playing with Amalia, a girl of 6 years old, to find the missed treasure. As you can see, she was with a costume of a pirate for make it more real. She was really exited and happy with the game. At the end, she finalized saying to me "I love you to much, "tía" Andrea". Those memories fills my heart and brings me energy for every difficulty of my day, and thats why I like this picture so much.

Escuela Monseñor Enrique Cornejo
Sagrada Familia, Región del Maule - Jenuary Team 2017

The love of the kids its amazing, but there's other thing wonderful too. As a team, we understand each other as a family. We are really close friends, and if something is wrong with one of us, we work on group to help the one whose sad, or stressed. Also we make parties and we have fun together. I don't know what i would do without this team, I love them too much.

If you are interested on the foundation, here is a link of it:

Music in my life


It's simple. Music is part of us.
Every situation has a song, and if there's not, we can creat it.
Music it's literature and melody combinated in perfect sincronization to express the deeper feelings of our hearts.

I really don't remember the music I used to like when I was a child. I just remeber that I used to like everything that my sister used to listen, so that includes music of groups like "La oreja de Van Gogh" , "Kudai" and "Belinda".

Years later I got fanatic (and when I say fanatic, i really mean that I got crazy) of Avril Lavigne. I used to hear her music ALL the day. My family was bored of the same songs all the day, all the week, all the month and all the year. So after 3 years of torture they decided to give me for birthday gift a ticket for one of her shows. IT WAS AMAZING. But after that, I don't know why, i stoped to listen her. Actually now I dont like it.

After that, I traveled to Finland as an Exchange student, and probably for the distance, I started to listen chilean music. Untill now, Chilean music is my favorite.
It's weird but my favorite Singer it's Violeta Parra. She is ART.
But also I like others chilean singers and bands, like Victor Jara, Chancho en Piedra, Los Prisioneros, Francisca Valenzuela, Mon Laferte, Villa Cariño and Los Tetas.
This ones are my favourite songs of this singers and bands, if you want to hear one.

Violeta Parra - Run Run Se Fue Pal Norte
Victor Jara - Deja La Vida Volar
Chancho En Piedra - Animales Disfrazados
Los Prisioners - Quien mató a Marilyn?
Francisca Valenzuela - Prenderemos Fuego Al Cielo
Mon Laferte - Soy
Villa Cariño - Serenata Cruel
Los Tetas - La Medicina

As you can see, I like all types of music, but Chilean.

It's dificult to define an instrument that I like the most. But I love the guitar played as Violeta does. I think that guitar is the instrument more esential for bands now.
I'm really a mess in music. I never learnd to play an instrument, but almost all my friends play one.
I have friends who plays the bajo, others who plays the viola, and others who play the drums.
I just dance.

When I was younger, I was on a dance Company. We used to dance movies songs, so the ones who I remember the most are the introduce songs of The aristocats, Spirit, Alice in the  wonderland, Footlose and Saturday night fever.
In resume, music has been always part of my life, for listening or for dancing.
Thanks.

My favourite pice of technology

My generation, luckily born in the boom of technology. Things started to change dramatically, and in one year the same object were 100 times better than it was before. Also things started to be more chipper and accesible, so almost of population had something technologic in their houses.

Old telephone of my house.

Definitely for me the most important pice of technology is the telephone. When I was a child, the most exciting thing were call your friends and talk for hours after school. Also were really exciting call my uncle that lived in Santiago. Telephones makes distance shorter.
So practically I always had a telephone in my home, but my own cellphone arrived on the 2008 Christmas. I were really happy and I get crazy downloading ringtones for it.
After that, I had 7 different models of cellphones. In the beginnings I used it for call people, but after some years cellphones get more usefully for text people, do some maths problems, search on the internet, and now it's practically for everything. So that's why I use it almost all the day.
I like it because makes my day easier and also because makes me be on contact with people who I love. I think that my life without it will be a completely mess. I probably get late to all my meetings, and I will miss my mum and family so much that I will search a place closer to them for study.
