Monodisperse Nanoparticles : Establishing Uniformity!

We have been taught since a very small age that to sustain anything in this world, it must be balanced, uniform. Be it the philosophical, non-physical things or a more practical approach, everything requires a balance, uniformity and stability for proper functioning. Nanotechnology also has many defect points of irregular distribution disrupting the stability and balance of the product.

The modern processes employed for the synthesis of various clement under nanotechnology fails to achieve the perfect final stage due to non-uniform distribution of particles. Thus, it is important that the material should be uniform in terms of distribution and porosity. But this also calls for the strong interparticle force. This is achieved by Monodisperse Nanoparticles.

To understand this concept, let us take an example of colloidal silica of Monodisperse form. In order for providing sufficient stability to the crystal of the colloid, Monodisperse of the same should be of higher stability, i.e. of higher uniformity.

NanoRods : Introducing A Unique Side Of Nanotechnology!

This world is advancing at a rate of blink. With so many inventions, achievements, experiments many new facts have come and many hidden secrets are revealed. There was a time when life size machines for eg, computer were operated but with passage of time, human due to his curiosity and needs has dug deep in the inside of everything, thus replacing those machines with small microchips. This is all possible due to nanotechnology.

Maintaining the same legacy a new form of nano product has been invented, it is NanoRods.  Let’s take every aspect of this morphology step by step. Talking at first, about its production, then it can be easily synthesized from metals or semiconductor through direct chemical process.

Then second comes the dimensions of this product; it is in the rage of 1nm to 100nm. Different combinations of the ligands decide the shape and bond of the rod. It also determines its strength. This is also a factor upon which the elongation and growth of the rod depends during its manufacture.

Nanorod finds application in so many fields persisting in this world. The basic uses are in as display technology, owing to its reflectivity and electrical sensitivity, micro electromechanical systems or MEMS, etc.

When it is mixed with the nanoparticle of noble metals, then it becomes a Theragnostic agent. There are different types of rods available in market. They are element and metal oxide rods. The element rod is a gold nanorod and under metal oxide rod we have iron hydroxide, iron oxide and manganese oxide.

Methods Of Synthesis Of NanoRods!

There many methods for the synthesis of nanorod but the best and reliable method is cation exchange method. Even hetero structured rods can make by using this method. Also, as this method depends on the surface area therefore owing to the higher surface area of the product, cation exchange is faster, hence synthesis is faster.

So when you go out to buy the product, keep in mind your requirements, dimensions, ratio and also the synthesis as all these points will help you in selecting the quality product.

Nano Products Are Now The Bestselling Products Around!

There have been many experimental revelations that have been seen in the recent years. Many new technologies have dealt with metals and their properties. Many scientists have dedicated all their life’s efforts into creating some products that have surely changed the phase of the world as we know it.

Metals are the earth abundant resource that is provided to us, mankind, to progress and flourish in life. Though all these metals aren’t readily available at all times, they are very useful. Since they aren’t replenishable very soon, sustainable development has become very important in the world as of today.

Scientists over the years have come up with something very interesting called Nano Products. These products are basically fine sheets of metal that are only a nanometre thick. There are so many uses for this product and many industries are in dire need of the same.

This item comes in many different useful metals with various properties such as iron nano, tungsten nano, copper nano, graphene nano etc. These products also come in powdered form. Each of these powders are used for different purposes at industries such as iron production houses, steel manufacture, car and other engine manufacture etc.

Nano Products Are Now Dealt With By Many Suppliers!

These products of nano are now available at many online stores. There are suppliers all around the world who are in contact with their customers throughout the process. Once purchased using debit card, credit card or cash on delivery, the suppliers ensure that the product is packed and shipped off to the location in the address provided.

There is no need to worry about costs and quality ratios either. All suppliers now want customer loyalty so they provide only the best products around. Make sure you get your product shipped to your desired location today!

Monodisperse Nanoparticles – Preparation, Properties and Uses

The enamouring and strange properties of nanoparticles have received a lot of attention, especially their uniformity in size in dispersed level. Monodisperse Nanoparticles are particles in the size range of 1nm to 500nm with a standard deviation in size of particles in a particular solution not exceeding 15%. The best monodisperse solutions available for industrial use have a standard deviation in size of close to 5%.  Spherical gold, silver and Aluminium trioxide nanoparticles are a few examples of monodisperse particles used in industry.

Preparation

During early days in the nanotechnology industry, the preparation of monodisperse particles was done starting with a polydisperse solution or solution with high particle size variance. Particles of a particular size were selected through very slow filtration processes. These process were not only extremely costly but also were expensive and inefficient.

Today, preparation of Monodisperse particles is done directly, after a small quick nucleation process particles are allowed to grow interracially either by slow heating or by digestive ripening. Through equal growth rates, size equilibrium is soon achieved where the standard deviation falls below 10%.  Experienced manufacturers can produce monodisperse particle with size variance as low as just 5%.

Properties and Uses

The properties at the nano-scale are drastically different from those at the micro-scale. Especially, monodisperse particles show unique optical, electrical and chemical properties. Owing to these properties monodisperse nanoparticle manufacturers have been under strain to produce high quality, stable monodisperse solutions through novel and affordable processes.

The gold monodisperse nanoparticle solutions, which are generally stabilised in the form of a sol in aqueous chloride salts, have been used widely as contrast agents for electron microscopy experiments. Their ability to interact differently with particles of different sizes makes them appropriate for medical imaging purposes. Cancer cell diagnosis, location and treatment have been assisted by use of inert silver or gold monodisperse particles.

Due to high conductivity and super paramagnetic properties monodisperse particles of Silicon dioxide and Alumina have been used in electronics and semiconductor based devices. Large surface area and uniformity in size of monodisperse particles makes them ideal for use as catalysts.
