Nanoparticles
Nanometer-sized particles that are nanoscale in three dimensions. They include nanocrystaline materials; NANOCAPSULES; METAL NANOPARTICLES; DENDRIMERS, and QUANTUM DOTS. The uses of nanoparticles include DRUG DELIVERY SYSTEMS and cancer targeting and imaging.
Year introduced: 2007
Calcifying Nanoparticles
Protein-mineral complexes that comprise substrates needed for the normal calcium-carbonate-phosphate homeostasis. Nanobacteria was the prior name for the particles which were originally thought to be microorganisms.
Year introduced: 2012
Magnetite Nanoparticles
Synthesized magnetic particles under 100 nanometers used in many biomedical applications including DRUG DELIVERY SYSTEMS and CONTRAST AGENTS. The particles are usually coated with a variety of polymeric compounds.
Year introduced: 2011
Metal Nanoparticles
Nanoparticles produced from metals whose uses include biosensors, optics, and catalysts. In biomedical applications the particles frequently involve the noble metals, especially gold and silver.
Layer-by-Layer Nanoparticles
Nanostructures fabricated by assembly of ordered layers of known compositions primarily through electro-static interactions. Such nanoparticles can be used for targeted delivery of complex components in ordered release patterns.
Year introduced: 2023
Magnetic Iron Oxide Nanoparticles
Synthesized nanoparticles related to iron oxide crystalline structures with magnetic properties useful for biomedical applications. Examples include hematite, magnetite and maghemite nanoparticles.
Year introduced: 2021
Multifunctional Nanoparticles
Nanoparticles that are engineered to have two or more physical properties.
Year introduced: 2020
Quantum Dots
Nanometer sized fragments of semiconductor crystalline material which emit PHOTONS. The wavelength is based on the quantum confinement size of the dot. They can be embedded in MICROBEADS for high throughput ANALYTICAL CHEMISTRY TECHNIQUES.
Year introduced: 2004
Microplastics
Plastic particles, less than 5 millimeters in diameter, that are generated from the degradation of larger pieces or are manufactured to be microstructures or smaller.
