Developed in partnership with Argonne National Laboratory, this kit gives your students the opportunity to apply a revolutionary nanotechnology manufacturing technique to grow nanoscale and microscale copper wires. Using a unique ultra nanocrystalline diamond (UNCD) electrode, students use traditional electroplating and lithography (E&L) techniques to grow pattern-shaped wires that become the essential components that can be used to fabricate optical and electrical sensors and other devices. Kit covers the following concepts:

• Measurement scales/perspectives
• Unique proper ties at nanoscale
• Fabricating nano/microscale structures
• Creating nano/microscale lithographic wire patterns
With this technology, students will make a wire lithograph and a conductive pressure sensor:

Activity 1: Making a Wire Lithograph
Students incorporate the UNCD electrode in a traditional electroplating apparatus and apply a 9V potential to electroplate star wire patterns. Depending upon electroplating time (minutes), students create and transfer invisible (nanoscale) or visible (microscale) wires in a star pattern onto sticky tape. In the process, they learn directly about scale (nano to micro) perspective. Students observe these wire patterns placed on microscope slides under low (<100X) magnification. They assess how electroplating time (electrodeposition) affects wire length (and corresponding wire pattern visibility) and how wire patterns can be consistently produced and reliably transferred onto a flexible support medium (sticky tape). These learned skills form the basis for future student design applications such as incorporating copper wire lithographs into sensors or creating light diffraction gratings.

Activity 2: Making a Conductive Pressure Sensor
Students apply their knowledge of nanomanufacturing (E&L) to create nanowire and microwire patterns that can be used to create a pressure sensor. Students learn what a pressure sensor is and use their observational electrodeposition data (from the previous activity) to design, manufacture, and test a conductive “bridge” (pressure “sensor”) to illuminate a 9V LED lamp.

Kit also includes an access code for downloadable activity guide and other support information, including teacher guide, student guide, glossary, background information (Learning About Nanotechnology), videos (Nano Frontiers and Nano Manufacturing: Electroplate and Lift Lithography - Making Nanowires), PowerPoints® (Making a Microwire Lithograph and Nano Technology: A Closer Look at the Universe of “Little”), and A Closer Look at Nanowires poster. For use by 40 students working in groups of 4.
