Nanoscale 3D printing of metallic glass
Nanoscale 3D printing of metallic glass is the fabrication of amorphous metal-alloy structures from tens of nanometers to hundreds of micrometers, using rapid heating and cooling that shapes the alloy without letting it crystallize.
Nanoscale coordination polymers
Nanoscale coordination polymers (NCPs) are hybrid nanomaterials self-assembled from metal ions and organic ligands through coordination bonds, first reported in 2005 and studied for drug delivery, biomedical imaging, and biosensing.
Nanoscale magnetic resonance imaging
Nanoscale magnetic resonance imaging, or nano-MRI, pushes MRI resolution from tens of micrometers down to the nanometer scale, using diamond nitrogen-vacancy centers and other spin sensors to approach imaging single biomolecules.
Nanoscale nuclear magnetic resonance
Nanoscale nuclear magnetic resonance (nano-NMR) is NMR spectroscopy and imaging on nanometer-to-micrometer samples, using magnetic resonance force microscopy and nitrogen-vacancy centers in diamond as sensors.
Nanosecond
A nanosecond (ns) is a unit of time equal to one billionth of a second, the timescale of fast electronics; light travels about 1 foot in it.
Nanosheet CMOS
Nanosheet CMOS is a transistor technology in which each MOSFET channel is a stacked, gate-all-around nanosheet, replacing FinFETs at 2-nm-class nodes; Samsung, Intel, and TSMC all adopted it.
Nanoshells
Nanoshells are spherical nanoparticles consisting of a silica core covered by a thin gold shell, whose optical resonance is tuned into the near-infrared, mainly for photothermal cancer therapy.
Nanosphere lithography
Nanosphere lithography (NSL) is an inexpensive, high-throughput nanofabrication method in which self-assembled monolayers of nanoscale polymer or silica spheres serve as masks for patterning periodic nanostructures.
Nanospheres
Nanospheres are solid spherical nanoparticles, typically 50–1000 nm (gold ones 5–15 nm), without a membrane, used as drug carriers, imaging agents, and lithography masks; distinct from hollow nanocapsules.
Nanosponges
Nanosponges are nanoscale particles with a porous, sponge-like network that trap other molecules, used either for controlled drug delivery or as cell membrane-coated decoys that neutralize bacterial toxins and venom.
Nanospray desorption electrospray ionization
Nanospray desorption electrospray ionization (nano-DESI) is an ambient mass spectrometry method reported in 2010, in which a solvent bridge between two capillaries dissolves analytes from a surface for imaging.
Nanostructured thermoelectrics
Nanostructured thermoelectrics are thermoelectric materials given nanoscale features such as grains, precipitates, and superlattices to scatter phonons, raise the figure of merit ZT, and improve waste heat recovery.
Nanotec Electronic
Nanotec Electronic is a German manufacturer of stepper motors, brushless DC motors, integrated motors, and motor controllers, founded in 1991 and headquartered in Feldkirchen near Munich, serving automation, medical, and semiconductor industries.
Nanotechnology
Nanotechnology, also known as nanotech, is the understanding and control of matter at the nanoscale of 1 to 100 nanometers, applied in electronics, medicine, and energy.
NanoTherm
NanoTherm is a magnetic hyperthermia therapy in which iron oxide nanoparticles injected into a tumor are heated to destroy cancer cells, developed by Berlin's MagForce AG.
Nanothermometry
Nanothermometry is the measurement of temperature with nanoscale spatial resolution, reading temperature-dependent optical or electrical signals from nanoscale probes such as luminescent nanoparticles in cells, tissue, and devices.
Nanotip electron source
A nanotip electron source is a sharp metallic or semiconducting cathode whose nanometer-scale apex emits bright, highly coherent, ultrashort electron pulses used in ultrafast electron microscopy and attosecond science.
Nanotoxicology
Nanotoxicology: the toxicology of engineered nanomaterials and nanoparticles. Emerged in the 1990s from airborne-particle studies, established 2004; studies ROS, genotoxicity, dosimetry, REACH, NIOSH limits.
Nanotribology
Nanotribology is the branch of tribology, the science of friction, wear, and lubrication, that studies interacting surfaces in relative motion at scales from single atoms to the microscale.
Nanotribometer
A nanotribometer is an instrument for measuring friction and wear in sliding contacts from nanometers to micrometers, filling the gap between AFM measurements and conventional macroscopic tribometers.
Nanotwinned diamond
Nanotwinned diamond is a synthetic polycrystalline diamond with twin boundaries a few nanometers apart, reported in 2014 to be harder than natural diamond and more heat resistant.
Nanotwinned materials
Nanotwinned materials are crystalline materials, most often face-centered cubic metals, containing nanoscale twins below 100 nm spacing that strengthen like grain boundaries while preserving ductility, with uses in microelectronics.
Nanotwinned metals
Nanotwinned metals are crystalline metals, most often FCC, containing a high density of nanoscale twins below 100 nm, combining high strength with good ductility; applications include microelectronics and coatings.
Nanotyrannus
Nanotyrannus lancensis, a small tyrannosaur dinosaur from the latest Cretaceous Hell Creek Formation, long debated as a juvenile T. rex but confirmed in 2024-2025 studies as a distinct genus coexisting with Tyrannosaurus rex, with a second species N. lethaeus.
Nanou ASMR
Nanou ASMR is the handle of Nanou Philips (born 2007), a Belgian ASMR creator from Damme. Active since January 2019, she runs a family-produced YouTube channel with about 1.9 million subscribers, plus TikTok, Twitch, and TWLV merchandise.
Nanovaccines
Nanovaccines are nanoparticle-based vaccine platforms (lipid nanoparticles, VLPs, ferritin, OMVs) that protect antigens, target immune cells, and co-deliver adjuvants; approved examples include Comirnaty, SpikeVax, and virosome vaccines.
