DIFF Subclass Not Allocatable
B82Y

SPECIFIC USES OR APPLICATIONS OF NANOSTRUCTURES; MEASUREMENT OR ANALYSIS OF NANOSTRUCTURES; MANUFACTURE OR TREATMENT OF NANOSTRUCTURES

Introduced: January 2011

Description

B82Y covers the practical application, characterization, and processing of nanostructures across diverse industrial and scientific domains. This subclass encompasses devices and methods utilizing nanoparticles, nanofibers, nanotubes, and other nanoscale materials in electronics, medicine, catalysis, energy storage, and environmental remediation. It includes techniques for measuring nanostructure properties, analyzing their behavior, and manufacturing or treating them through chemical, physical, or mechanical means. Adjacent class B82B addresses foundational nanotechnology principles, while B82Y focuses on the downstream realization of nanostructures in specific functional applications.
