he tissue, and to measure changes in those signals in response to cardio- or neuro-stimulating drugs.

Researchers were also able to construct bioengineered blood vessels, and used the embedded technology to measure pH changes as would be seen in response to inflammation, ischemia and other biochemical or cellular environments both inside and outside the vessels.

Though a number of potential applications exist for the technology, the most near-term use, Lieber said, may come from the pharmaceutical industry, where researchers could use the technology to more precisely study how newly-developed drugs act in three dimensional tissues, rather than thin layers of cultured cells. The system might also one day be used to monitor changes inside the body and react accordingly, whether through electrical stimulation or the release of a drug.
