New research by an international team of chemists describes a new type of artificial cell that can communicate with other cells within the body—with potential applications in the field of smart pharmaceuticals.

“In the future, artificial cells like this one could be engineered to synthesize and deliver specific therapeutic molecules tailored to distinct physiological conditions or illnesses—all while inside the body,” explained Sheref Mansy, a professor in the University of Alberta’s Faculty of Science who conducted the study in collaboration with researchers at the University of Trento in Italy.

The artificial cells work by detecting changes in their environment within the body. In response, the artificial cell creates and releases a protein signal that influences the behaviour of other cells within the body.

“In this way, th...
