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
