In biochemistry experiments, proteins often serve as carriers to transport drug molecules to specific cells in the body.

This catalyst needs to be attached to a solid carrier in order to maintain stable activity.

In gene therapy, scientists use viruses as carriers to introduce normal genes into patients' cells.

In industry, activated carbon is a commonly used carrier for supporting metal catalysts.
