Green Algae in the Drug Industry?

As we reflect on how important it is that our drugs and vaccines are grown in culture cells of yeast and mammalian cells we also realize how expensive it is. Even before production begins of cells to make medicine researches must invest over $600 million to build a facility that can make them. The facilities have to be sterile and the mammalian cell cultures are difficult to make and maintain. So before a drug is even tested huge amount of money is already used up. In the article, Drug Production Gets Aquatic by Lauren Gravitz, the author discusses how using green algae, more specifically, Clamydomonas reinhardtii, can be used to make the industry more cost effective.

For green algae to grow and maintain itself all it needs is light and carbon dioxide from the air. Unlike mammalian cell cultures which needs expensive food for maintaining itself. The green algae is also better at folding the proteins it creates for medicine. Whereas the mammalian culture cells are not as effective in doing requiring an additional process. It was quoted that the cost of one gram of Tysabri, a drug for multiple sclerosis, is about $150, whereas at the rate the green algae makes it, it is approximately a nickel. The only drawback to algae is that it does not add a sugar to the end of the protein which helps the absorption of it into the body. This sugar is not always needed and if it is needed the green algae can be manipulated into doing so, like yeast was. This is a very valuable area of research that can prove to lower prices of drugs for everyone.

Why am I interested in being a Biomedical Engineer?

Ever since I was young I always loved building things with legos. I would buy a pack of legos and let my imagination run wild. I would create objects from space ships to castles. When I was young I always wanted to help people also. I would watch doctor programs and learn how to treat wounds and prevent infections. I would learn how to diagnose sickness and other health issues. While I was growing up and trying to decide what major I wanted I was lost in a loop. I wanted to be an engineer because I loved building things but I also wanted to be a doctor because I loved helping sick and injured people. When talking to my councilor she suggested for me to look into biomedical engineering. So I went home and followed her advice and looked it up. Too my surprise it was the combination of both being an engineer and a doctor. I would be able to combine my passions of both building things and helping those who needed help at once.

The field I am most interested in is with nanotechnology. Nanotechnology can revolutionize medicine by having nanobots deliver medicine directly to the area ailed. This is especially important to cancer patients. The nanobots could apply chemotherapy directly to the cancerous area.
