Tiny 'lab-on-a-chip' detects pollutants, disease and biological weapons
Date:2/17/2009

pioneering the "lab on a chip" concept. The nanolabs can be used to evaluate several biological processes with practical applications, such as microbes in water, stem cells, or breast cancer development. Prof. Shacham-Diamand's active lab group publishes a major paper about once a month in this field, most recently in the journal Nano Letters.

Environmental, Medical and Defense Uses for "Mini-Labs"

Partnering with other Israeli scientists, Tel Aviv University is currently building and commercializing its water-testing mini-labs to measure and monitor how genetically engineered bacteria respond to pollution such as E. coli in water. Cities across Israel have expressed interest in the technology, as has the state of Hawaii.

But other uses are being explored as well. Funded by a $3 million grant from the United States Department of Defense Projects Agency (DARPA), the new lab-on-a-chip could become a defensive weapon that protects America from biological warfare. His system, Prof. Shacham-Diamand says, can be also modified to react to chemical threats and pollution. With some tweaking here and there, it can be updated as new threats are detected.

Prof. Shacham-Diamond's research has also attracted the interest of cancer researchers around the world. He recently addressed 400 physicians at a World Cancer Conference who are seeking new devices to measure and monitor cancer and pharmaceuticals. "They need sensors like Tel Aviv University's lab on a chip. It's a hot topic now," says Prof. Shacham-Diamond.
