• Many diseases are threatening human all over the world. Especially, cancer, AIDS, tumor are extremely dangerous
• Brand “new” diseases such as SARS, “mad-cow” disease, and Swine Influenza (SI) are breaking out.
Motivation - Today’s climate

• Small volume of reagent samples, required for analysis.• Low power consumption, lasts longer on the same battery.• Less invasive, hence less painful.• Integration permits many systems built on a single chip.• Batch processing can lower costs significantly.• Existing nanotechnology can be used to make these devices.

Competitor Analysis
Competitors
Human doctors:Great, but have limitationfor major new disease since they cannot go intoHuman body
Drug delivery:Works well like tablets, butlimited target, operation
Capsule Endoscope:Great for taking pictures,communication by RFIDbut low quality, no control
Nano Bug:Not realized yet, too conceptual

Blueprint of Nano Surgeon
10-20 years in the future… What do we mean by a nanosurgeon? Imagine…
…a EMT/first responder better able to address medical emergencies before arriving at the hospital with a simple injection.
…a self-administered at-home first-aid kit capable of “surgery.”
…persistent in vivo health monitoring.
…surgery/repair on the cellular and molecular scale.
