My Summer David Klee
My Research Nanotechnology – the study of
manipulating matter on an atomic and molecular scale
Biotechnology – the use of microorganisms or biological substances to perform specific industrial or manufacturing processes
Pharmaceutical use of Nanotechnology in Tumor Cells
Nano-particles designed to carry drugs specifically to tumor cells
In a University of Michigan study, 35% of the mice given the drug-laced nano-particle survived compared to 0% of the mice who were given the nanoparticle or drug (methotrexate) separately

Use of Nanotechnology in Computing and Electronics Graphene – an extremely thin sheet of pure
carbon rings Thin, transparent, and highly conductive
Will likely replace silicon in electronic or memory devices Graphene conducts electrons 100 times faster
than silicon A graphene ultra capacitor holds twice the storage
of a traditional ultra capacitor
Biotechnology: Synthetic Genomics Scientists placed artificially-produced genes
into a colony of bacterium In two days the bacterium showed characteristics of
the implanted genes
Many people question this method of biotechnology because new species are created that could disrupt present ecosystems
Use of Synthetic Genomics Scientists altering the
genomes of viruses to develop vaccines
Developing algae that produce biofuels without the environmental footprint of harvesting fossil fuels
Some scientists were able to use a colony of bacterium to store data
Biotechnology: Regenerative Medicine Extracellular matrix (ECM) is placed in the
injured tissue or muscle and over several weeks the tissue heals to its original strength
Biotechnology: Regenerative Medicine It works because the ECM naturally
summons stem cells to the area which develop into the desired cell type based on the location of the injury
An ex-Marine, who lost 70% of his thigh muscle from a car bomb, was able to regain 103% of his natural muscle mass using ECM and physical therapy
Biotechnology:Potential AIDS Cure By removing certain receptors on T cells,
scientists pioneered a method to create cells that are resistant to the HIV virus
Scientists are able to take blood from a patient, alter the T cells within the blood, and transfuse this blood back to the patient. Although this process significantly decreases the
presence of the virus in the bloodstream, latent viruses will still remain
What I did over the summer I spent a lot of time at my camp in Schroon
Lake I also played some lax, tennis, and went
sailing
