摘要：

We demonstrate the first three-input molecular AND logic gate based on three chemical inputs as a direct way of detecting congregations of chemical species. The AND gate operates in water and responds to Na+, H+, and Zn2+ inputs with an enhanced fluorescence signal when pre-set concentration thresholds are exceeded. Future lab-on-a-molecule" devices could have application in medicine for rapid disease screening. Copyright © 2006 American Chemical Society."
