Travis Norrell GEEN 1100 Nanotechnology Since the early 1970s, scientists have been creating nanostructures, devices as small as 40 nanometers long. Since then, there has been a significant amount of speculation as to the possibilities of this new technology. Today, ideas range from developing laser goggles for the military to creating a new kind of sock that will not smell badly. The versatility of nanotechnology will allow it to affect people in all aspects of life, including the medical field. Specifically, the potential for nanotechnology to help people with cardiovascular diseases is immense. Countless people die every year as a result of cardiac arrest or some other implication involving the heart. The main cause of a heart attack is a blood clot inside an artery that slows the blood flow to an area. Due to less blood in the local area, there is less oxygen and cells die. To fix the problem at the source, nanotechnology provides a means of opening up the artery. Scientists are

Unformatted text preview: developing nanodevices that will remove the clot ahead of time and save lives. If a patient has a clot surgically removed without nanodevices, there is a 30% to 50% chance of a “relapse”, where the clot forms again. These nanodevices can proactively target future potential threats. Nanotechnology does not only provide a means for aiding patients, but it also provides scientists with more information regarding the heart. By creating nanoscopic probes, scientists are able to learn a great deal more about cardiovascular health. http://www.sciencedirect.com/science? _ob=ArticleURL&_udi=B7MDB-4NC62JR-3&_user=918210&_coverDate=03%2F31%2F2007&_rdoc=3&_fmt=full& _orig=browse&_srch=doc-info(%23toc %2323226%232007%23999969998%23647492%23FLA%23display %23Volume)&_cdi=23226&_sort=d&_docanchor=&_ct=11&_acct=C000 047944&_version=1&_urlVersion=0&_userid=918210&md5=c06215fe a1de3014f92ec182118e9880#secx12...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
