Nano-computed tomography
Nano-computed tomography (nano-CT) is a nondestructive X-ray tomography technique that resolves sample interiors at sub-micrometer to nanometer resolution, down to about 50 nm in laboratory instruments, and is used on materials, batteries, bone, and archaeological samples.

Nanofluidics is the study of fluid flow and structure in artificial nanopores and nanochannels around 100 nm down to sub-nanometer scale, enabling ion selectivity and osmotic energy conversion.
Nanofocused X-ray diffraction
Nanofocused X-ray diffraction is a synchrotron-based characterization method in which a hard X-ray beam focused to tens of nanometers maps strain, defects, lattice orientation, and phase in materials.
Nanoimpact electrochemistry
Nanoimpact electrochemistry, or NIE, is a single-entity electrochemistry technique in which nanoparticles randomly strike a biased ultramicroelectrode, yielding current transients used to size particles, study electrocatalysis, and detect biomolecules.
Nanoindentation
Nanoindentation is a depth-sensing indentation test that presses a sharp diamond tip nanometers into a material's surface, recording load and depth to extract hardness and elastic modulus.
Nanolattices
Nanolattices are three-dimensional lattice-structured mechanical metamaterials whose struts, plates, or shell walls have nanoscale dimensions, exploiting size effects to combine very low density, sometimes below water's, with strengths approaching steel.
Nanomaterial characterization
Nanomaterial characterization is the measurement of physical, chemical, and structural properties of nanoscale materials, such as particle size, surface charge, and morphology, using techniques like DLS.
Nanomechanical mass spectrometry
Nanomechanical mass spectrometry (NEMS-MS) is an analytical technique that weighs individual molecules, nanoparticles, and viruses by the frequency shift each causes in a nanoscale resonator, measuring mass directly without ionization and working even on neutral particles.
Nanoparticle
A nanoparticle, also called a nanoparticulate, is a particle with an equivalent diameter of roughly 1 to 100 nm that develops properties different from the bulk material.

Nanoparticle surfactants are surface-active agents built from solid colloidal particles, either bare particles or polar nanoparticle heads with hydrophobic polymer tails, that stabilize emulsions and foams.
Nanoparticle tracking analysis
Nanoparticle tracking analysis (NTA), also called particle tracking analysis, is a light-scattering microscopy technique that determines the size distribution and concentration of nanoparticles in liquid by tracking their Brownian motion.
Nanoparticle-on-mirror nanocavity
A nanoparticle-on-mirror (NPoM) nanocavity is a plasmonic structure where a metallic nanoparticle sits on a metal film separated by a nanometer spacer, confining light into the gap for single-molecule spectroscopy, sensing, and room-temperature cavity quantum electrodynamics.
