Celluar Lead Sensor

Lead poisoning is a public health concern - there is lead in soil, paint, water, and dust. Lead Poisoning is often caused by ingesting contaminated drinking water, or soil. It can cause neurological and gastrointestinal disorders, especially among children.

The legal limit of lead in drinking water is 15 parts per billion.

Current ways of testing for lead either require expensive chemical lab analysis or involve inaccurate home kits.

A lead detector, based on E. Col, is cheap, sensitive, quick, and specific

Our system involves a Lead detecting promoter, an amplifier, and an output of GFP. We're also working on a system to remove false positives.

Tristable Switch

The Tri-Stable Toggle Switch represents a continuation on the theme of the Toggle Switch begun by Gardner, et al 2000. The switch produces three distinct and stable outputs in response to three distinct inputs. Our approach to solving the switch is based on quantitative measurements in a pioneering effort to establish a standardized means of designing and debugging biological systems.
