Artificial cells get chatty

  June 2/9, 2008
Artificial cells that communicate chemically with bacteria open a new route to delivering drugs to diseased cells or antibiotics to harmful bacteria.

The polymer vesicles have sugars on their surfaces, which let them link to bacteria in the same way natural cells communicate with each other. The artificial cells transferred a dye from their interiors into the bacteria, showing that it should be possible to design artificial cells that can transfer drugs to specific types of natural cells.
