Cellular Engineering
Many researchers are developing methods that use bacteria to deliver drugs. These bacteria can be “programmed” to perform a specific task, and can be directed to go to targeted locations in the body. However, the bacteria may damage healthy organs or fail to deliver the medicine to the sick organ in the case of a malfunction. In such cases, a fail-safe mechanism is required to neutralize the bacteria and prevent damage. An antibiotic is generally suitable as the fail-safe agent.

Famous quotes containing the word engineering:
“Mining today is an affair of mathematics, of finance, of the latest in engineering skill. Cautious men behind polished desks in San Francisco figure out in advance the amount of metal to a cubic yard, the number of yards washed a day, the cost of each operation. They have no need of grubstakes.”
—Merle Colby, U.S. public relief program (1935-1943)
