Stopping Bacterial Infections Without Antibiotics

Because nanofactories are designed to affect communication instead of trying to kill the bacteria, they could help treat illness in cases where a strain of bacteria has become resistant to antibiotics.

"The work by Dr. Bentley is extremely exciting as he is using the ability of engineering to 'build' using nature based components," says Philip Leduc, associate professor in the Departments of Mechanical and Biomedical Engineering and the Lane Center for Computational Biology and Biological Sciences at Carnegie Mellon University. "Understanding the science of cells is wonderful, but then using these components and constructing systems that leverage biological advantages is a huge step forward. His work in this paper uses his synthetic biology approach to build new nanofactories toward new areas of antimicrobials as well as opening new findings in quorum sensing."

The nanofactories' ability to alter cell-to-cell communication isn't limited to fighting infections.

"Quorum sensing and signaling molecules are actually used to accomplish a lot of things," Bentley explains. "Sometimes disease develops because communication is not taking place—a good example is digestive disorders that involve an imbalance of bacteria in the digestive tract. In that case, nanofactories could be used to start or increase communication instead of disrupting it."
