Guided Assembly of Nanoparticles and Nanocontamination Control

Approach/Methodology:
The nanotemplate offers a simple means for controlling the placement and positioning of nanoelements through conductive nanowires. The nanowires can be manufactured in different patterns and designs using nanolithographic techniques or other self-assembly techniques. The nanoparticles can be aligned on the charged wires of the nanotemplate.

Results:
Preliminary results show the use of nanotemplating nanowires in the guided self assembly of nanoparticles along a 60 nm nanotemplate’s positively charged wires only. Techniques have also been developed to prevent or remove any nanoparticles that may deposit anywhere else.

Impact/Conclusion:
The nanotemplate and nanoelements can form a device or can function as a template to transfer patterned arrays of nanoelements onto another substrate. When the nanotemplates are moved with nano-precision accuracy and alignment, they can be used to deposit a wide variety of nanoelements into very closely packed columns or rows with a very narrow pitch.

Abstract:
Although self-assembly of nanoelements may produce uniform patterns or structures, such patterns are difficult to control and manipulate to produce specific design or structures. Nanotemplates will enable high-rate, bottom-up, precise assembly of nanoelements such as nanoparticles, carbon nanotubes, proteins.
