Nano Rods | Image Resource : nanoseedz.com

In terms of nanotechnology, the size of nano rods has different morphology. The nano rods are one-dimensional structures which offer a directed way for the electrical transport and these are mainly used in order to control the bandwidth which differs in the radius of a rod and by making use of a quantum size effect.

The dimensions of the nano rod usually range from 10-100 nm. These rods are mainly synthesized by using the semi-conducting metals and materials in the ration 5:3. The most common way of synthesizing the nano rods is by the direct chemical process.

A quantum dot has the capability to give a different form of the polymer. The solar cell can be intensified by using the effect called as quantum confinement that will affect the width and length of nano rods by assisting to thinner devices for best absorption of an incident light.

Various Formations of Nano Rods

Gold is considered as one of the excellent nano rod due to its potential in the biological sensing; it has the capability to absorb the refractive index at IR that elevates the accurate sensing. Along with the absorption, the rods can be high at a peak of IR by using laser emission. The gold nano rods are usually excited and they generate a remarkable amount of heat. This heat will enable thermal deconstruction of injured cells like a tumor or cancer cells.

If you purchase the nano rods which are made up of gold you can evidence its different optical properties because of a quantum dot effect. You can find these rods in a cylindrical shape and the size differs from 10-40nm in its width, however, it can able to intensify to 100s when it comes to length.

Biological applications of gold nanorods

Gold nano particles are used as a supplement for the aesthetic reason. These nano particles can be adjusted in order to scatter and absorb the light which is close to the infrared areas of an electromagnetic spectrum. This kind of property will result from assembling oscillations of electrons across the surface of a metal and these can be improved by modifying the environment, size or shape. The nano particles of gold have a rod like structure which is of specific interest due to its anisotropic shape.

The absorbable form of the gold nano rods involves 2 bands of absorption: -

Because of the absorption through the long axis

Another one is because of the absorption through the short axis.

If the length of a rod intensifies, it performs a red shift longitudinal band in cooperation with intensifying in extinction coefficient. Due to sensitivity to modify in the local atmosphere and optical control, the gold nano rods are used for biomedical imaging, Photothermal therapy, materials for sensing and drug delivery.

The biomedical applications of the nano rods involve cancer imaging by making use of improvised scattering property and the photothermal therapy by making use of the improvised property of nano-radiative photothermal property.

Carbon comes in many forms like lead, graphite, as well as in the form of diamonds. Initially, there were only few forms of carbon like diamond, graphite, and amorphous carbon but then few more forms were discovered like carbon nanotubes and fullerenes and it is then that Graphene was first introduced. Graphene is a honeycomb grid made up of carbon atoms and now in all initial forms of carbon, grapheme is the highly used metal like bonded on top in the form of graphite forming lead of the pencil, rolled into carbon nanotubes or folded in fullerenes.

Graphene is known as the two-dimensional metal as it extends only in length and width and is found to be emerging as one of the most super powerful and efficient nanoparticles as they exhibit some excellent and unique properties which make them totally different. Graphene is prepared by many processes and different methods produce different kinds of grapheme having variant qualities which may also cause defects, lead to impurity, structural disorders and wrinkles in graphene sheets.

Preparation

There are various methods to produce Graphene. Graphene is prepared with many toxic metals which lead to generation of many hazardous wastes leading to pollution and harm to environment. However many environment friendly approaches needs to be developed for such production.

Currently the various techniques used in production of Graphene are micromechanical cleavage, chemical vapour deposition, liquid phase exfoliation of Graphite, unzipping of carbon nanotubes and many more. Continuous and regular efforts are made by big industries, R&D institutes, universities and companies as large scale production is needed and so that the cost to buy graphene is reduced and high quality graphene is produced.

The colloidal features suspension of a gold nanoparticle of submicrometre sized used within a fluid like water is colloidal gold. This liquid colors rich red for nanoparticles which are less than 100 nm. For particles more than 100 nm, this liquid turns blue or purple color. For centuries artists has been used them due to their reflectivity in light.

In recent times extensive research has proved the eligibility of the particle to be used for various advanced technical applications like sensory probes, drug delivery, organic photovoltaics, and theurapetic purposes in various medical and biological uses. One can tune the optical and electrical properties of gold nanoparticles.

Method of Gold Nanoparticle Synthesis

There are many ways to synthesize and produce gold. Gold nanoparticle synthesis can occur using –Turkevich method, Brust method, Perrault method, Martin method, Navarro method, Sonolysis, Block copolymer method and green chemistry techniques.

Generally this nanoparticle can be produced by some liquid chemical technique by reducing chlorauric acid. The solution after dissolving it is stirred at a fast pace. This colloidal nanoparticle gold is then added with a reducing agent.Au3+ ions are reduced to Au + ions. A disproportionate response occurs. Here Au3+ and 2Au+ ions get produced. A stabilizing agent helps the nanoparticles to be stable. The nucleation centre in this case surrounds around the Au0 atoms.

Properties of gold nanoparticles – optical and electrical

The optical interactions in between light source and gold nanoparticles are really strong. Various applications of the particle are made due to the gold nanoparticle synthesis and optical properties. It is also dictated by the particles size, physical properties, dimensions and environment.

The electric field of any light source which is oscillating close by colloidal nanoparticle gold reacts with the free natured electrons. Thus an accumulation of electron oscillation occurs which can also be termed as resonance of the frequency of the light source visible. These oscillations resonant in nature are also termed as surface plasmas.

If large amount of salt is added into a solution of gold nanoparticles the same phenomenon can be observed. The surface area charged because neutral in nature. Hence the gold nanoparticles accumulate. The solution changes its color from red to blue here. Polymer coating is added to minimize this aggregation.

They are also coated with small amount of molecules and molecules of various biological recognitions. The modifications made on their surface made these nanoparticles of gold to be of great use in engineering, biological, medical and chemical sector.
