In the field of nano technology, the nano rods are gaining huge amount of attention from the science fraternity. The nano rods are actually one kind of object of nano scale. To be more specific, the dimensions of these rods range from 1 nano meter to 100. The synthesis of nano rods can be done with the help of metals or materials that are semi conductive in nature.
Talking more about the dimensions of the nano rods, the ratio between their length and width remains about three is to five. Direct chemical synthesis is the most widely used procedure to produce these rods. In order to produce nanorod of desired shape and size, certain assortments of ligands are used, which perform the role of shape/size control agents.
These ligands determine the shape of the rods. Apart from controlling the shape of the rods, the ligands also determine the physical characteristics of the same. Nano rods of various strength levels can be created in this way. The use of ligands determines how fast the rods would grow. Hence by maintaining a different growth rate, wide range of rods can be produced. In this way, suppliers are able to offer nano rods of different size for various purposes.
Get to know more about nanorod
There are many properties of nano rods that make them quite apt for bioscience. For example, nano rods made up of gold are very much useful for making biological sensing devices, mainly due to their optical properties. The absorbance band of nano rods alters as the refractive index related to the local material changes. As a result, it turns out to be easier to get accurate results through sensing.
The absorption peaks of nano rods associated with near-IR can be activated with the help of laser. The laser rays should be adjusted according to the absorbance band of the nanorod, which in turn can help destroy the malign or cancerous tissues inside the body. Owing to the quantum size effect, the rods of gold showcase many optical properties. These rods have length in nano meters, up to few hundreds.
Studying nanorods for better applications
In the present time, researchers are still trying to figure out the properties of nano sized rods. However, in order to completely exploit the exceptional properties of these rods, it is essential to have a strong extinction coefficient. This would help calculate the concentration of a solution, having certain absorbance level. As a matter of fact, there are numerous nanorod applications in the biomedical field.
With the passage of time, more studies are being carried out to unearth the other properties of nano rods. The nanorod suppliers in the online world can offer wide range of products. You can choose nanorods made up of zinc oxide, gold, and many more. Choosing the one completely depends on your requirements. So, go through the specifications before placing any order. In addition, also take a look at the reviews of the previous clients.
