On August 25, 2019, Alfa Chemistry announced that they can offer various metal nanomaterial products to meet the different needs of their customers.

Metal nanomaterials are metallic materials in which at least one dimension is nanoscale or the basic unit is nanoscale. Metal nanomaterials have good mechanical properties, surface effects, small size effects, long-lasting effects, macroscopic quantum tunneling effects, atomic diffusion behavior, catalysis and hydrogen storage properties. And the metal nanomaterials offered by Alfa Chemistry include functionalized nanomaterials, nanofoil, nanoparticle dispersions, nanoparticles & nanopowders, nanoprisms, nanorods, hollow nanospheres, nanotubes, nanowires, porous nanomaterials, quantum dots and other metal nanomaterials.

Functionalized Nanomaterials
Functionalization of nanomaterials is achieved by introducing small molecules or polymers on the surface of the nanomaterial. The surface coating of these nanomaterials determines their physical and chemical properties, particularly stability, solubility and targeting. Functionalized nanomaterial catalysts can be used in the catalysis of many known organic reactions. As a representative commodity of functionalized nanomaterials, functionalized gold nanorods (GNR) have been widely used in biomedical fields due to their unique optical properties and excellent biocompatibility.

Nanofoil
Nanofoil refers to a multilayer foil produced by vapor deposition of thousands of alternating nanoscale metal layers (Al, Ni, Au, etc.). Nanofoil is a controlled and affordable material that produces an instantaneous heat source to melt adjacent solder layers and bond the two components together. Because Nanofoil provides repeatable and reliable bonding, it has been used in many fields including electronics, automotive, biomedical, aerospace and defense industries.

Nanoparticle Dispersions
A nanoparticle dispersion is a series of suspensions of nanoparticles in water or an organic solvent. Compared with submicron sized particles, nanoparticles have a stronger tendency to polymerize. Nanoparticle dispersions generally provide phase stability, dimensional stability and hardness, which can be used to enhance the properties of the nanoparticles and control their function.

Nanoparticles & Nanopowders
Nanoparticles can be defined as nano-objects of all three external dimensions with nanoscale, with no significant difference between the longest and shortest axes, ranging from 1 to 100 nanometers (nm). Nanopowders are agglomerates of particles, nanoparticles or nanoclusters. The small size of the nanoparticles gives them a very high surface area to volume ratio, resulting in a large surface area and strong mechanical strength, optical activity and chemical reactivity.

Nanoprisms
Nanoprisms, also known as nanoplates, have a two-dimensional structure with parallel top and bottom and nanometer thickness. The shape of the nanoparticle determines many of its physicochemical properties. Compared to traditional nanospheres, nanoprisms have unique optical properties and offer potential for applications such as fluorescence spectroscopy, molecular sensing, biomedical diagnostics, cancer therapy.

Nanorods
Nanorods are a form of nanoscale objects. They range in size from 1 to 100 nm and their standard aspect ratio is 3-5. They can be produced by direct chemical synthesis of metal or semiconductor materials. Metal nanorods have unique optical properties that have reactivity to induce changes in the refractive index of the surrounding solution, making nanorods a useful tool for tracking binding events in different applications.

Hollow Nanospheres
Hollow nanosphere has a cavity and its size is in the nanometer range. Because of the large surface area of the hollow structure, the density of the hollow nanospheres is much lower than the density of solid counterparts having the same composition and size. And due to their unique structure, hollow nanospheres have large surface area, low density, good biocompatibility and high load capacity. Hollow nanospheres can be used as imaging contrast agents, drug delivery vehicles, anodes or cathodes for lithium ion batteries, nanoreactors, biosensors, and the like.

Nanotubes
Nanotubes are tubular nanomaterials. As inorganic nanotubes, metal nanotubes have a needle-like morphology, good adhesion and high impact resistance to many polymers, showing their ease of synthesis, high crystallinity, predetermined conductivity, good uniformity and dispersibility and other advantages.

Nanowires
The lateral dimension of the nanowires is tens of nanometers or less, the longitudinal dimension is unconstrained, and the ratio of length to width can be greater than 1000. Nanowires are also referred to as "quantum wires." Nanowires have high flexibility, high strength and uniform morphology. Nanowires also exhibit unique thermal, chemical, electronic, optical and mechanical properties. They can be used as chemical and biological nanosensors, nanowire lasers, nanowire batteries, and the like.

Porous Nanomaterials
Porous materials are a class of inorganic materials with open pore frameworks and large surface areas. Depending on the pore size, porous materials can be classified into three categories: microporous materials (pore size less than 2 nm); mesoporous materials (pore size between 2 and 50 nm); and macroporous materials (pore size greater than 50 nm). Microporous materials are commonly used in laboratory environments to promote non-contaminating gas exchange. Mesoporous materials have high surface area and large pore size and are therefore well suited for accommodating molecules of different sizes, shapes and functions. Electrodes with a macroporous structure can provide many opportunities to improve catalytic and energy storage properties.

Quantum Dots
Quantum dots are tiny particles or nanocrystals of semiconductor materials ranging in diameter from 2 to 10 nanometers. If electricity or light is applied to them, many types of quantum dots will emit light of a particular frequency, and these frequencies can be precisely adjusted by changing the size, shape and material of the dots. Quantum dots can be used for medical imaging and disease detection, solar cells, and photovoltaic devices.

“In response to different needs of our customers, we have decided to launch a wide range of metal nanomaterials that can be used in many applications including catalysis, medical imaging, disease detection, drug delivery, manufacturing of chemical sensors, biosensors, solar cell and photovoltaic devices.” Said Brenda Randy, the marketing manager of Alfa Chemistry. “we hope that customers from different industries will be able to find the products they need on our website.”
