Scalable Nanomanufacturing of Nanowire-Based Sensing Systems from Integrating Flow-Guided Assembly and Synthesis

Description :  

The objective of the investigator of this research is to develop a novel nanomanufacturing process for well-aligned nanowire-based sensors through biological template assembly. By eliminating variations in the dimensions and crystalline structures observed in bottom-up assembly, the investigator aims to achieve single molecule sensitivity in detecting molecules. This may be accomplished through the use of flow guided assembly of biomolecules, which could then be aligned and well-patterned on microscale substrates and further embedded in a polymer. Metallic nanowires may then be formed through electrodeposition and utilized as nanoscale thermocouples (nanoTCs) or thermopiles (nanoTPs). Nanotip induced welding could then be applied to create contacts for nanowire-based field emission transistors (nanoFETs). Chemicals and biological agents may then be evaluated using this novel sensing system in order to determine efficiency and sensing capabilities.
