description George Smith Overview

George P. Smith is an American biologist and biochemist who was awarded the 2018 Nobel Prize in Chemistry for his invention of phage display. Developed in 1985, this laboratory technique involves genetically modifying bacteriophages to express specific peptides or proteins on their outer coats, allowing researchers to study protein interactions and evolve molecules with desired binding properties. Phage display has become a standard tool in biochemistry, drug discovery, and the development of targeted antibody therapies.

help George Smith FAQ

What laboratory technique did George Smith invent?

George Smith invented phage display, a groundbreaking technique he first developed in 1985. This method involves genetically modifying bacteriophages so they express specific peptides or proteins on their outer surfaces.

Why was George Smith awarded the Nobel Prize?

Smith was awarded the 2018 Nobel Prize in Chemistry for his invention of phage display. He shared the prize with George Winter and Frances Arnold, who used his technique to evolve new proteins and antibodies.

How is phage display used in modern medicine?

Phage display is critical for discovering new drugs and targeted therapies. By displaying billions of different peptides, scientists can screen them to find the exact molecule that binds to a specific disease target, such as cancer cells.

What kind of organism is used in George Smith's phage display technique?

The technique uses bacteriophages, which are viruses that exclusively infect bacteria. Scientists splice foreign DNA into the phage's genome, forcing it to display the corresponding protein on its protective protein coat.
