Title:
NANOPARTICLE-BASED ELECTRICAL, CHEMICAL, AND MECHANICAL STRUCTURES AND METHODS OF MAKING SAME
Document Type and Number:
WIPO Patent Application WO2000020916
Kind Code:
A3
Abstract:
Nanoparticles are utilized to create, through deposition and patterning, functional electronic, electromechanical, and mechanical systems. At sizes ranging from 1 to 999 nm, the ratio of surface atoms to interior atoms becomes non-negligible, and particle properties therefore lie between those of the bulk and atomic materials. Monodisperse (i.e., uniformly sized) or polydisperse nanoparticles can form stable colloids or suspensions in appropriate dispersing media, facilitating their deposition and processing in a liquid state. As a result, printing technology can be utilized to deposit and pattern nanoparticles for mass production or for personal desktop manufacturing.
