Discussing Nickel Nanoparticles and Iron Oxide Nanoparticles

Nanotechnology is all about comprising nano particles that are the near-atomic size for constructing new structures, and to be used in various biomedical or industrial devices. Due to making various particles available for use at their nano level, this technology has found its application in various directions. But today we are discussing how Nickel nanoparticles are said to have a toxic effect.

According to the Department of Biology at a University in Iran (the Payame Noor University) and other young researchers and medical sciences department, a study was conducted on the effect of nickel nanoparticles which was found to have a bad after-effect.

Since the application of nanoparticles has expanded in the past decades or so in various industries for a multitude of purposes, it should not be a surprise, just like any other thing, that the use of nanoparticles has its own pros and cons.

A Case Study

The current study being quoted here was a study conducted not on any human, but laboratory rats. The results were shattering where a toxic effect was registered on the immune system of the lab rats. The test was conducted in 2 forms on 2 groups of rats, where for 7 days in a row, the rats were given a 25ppm dose of nickel oxide nanoparticle in food and water.

Upon observation, the rats were found to have increased levels of interferon and interleukin when compared with the other, a more controlled group that was served a lesser dose of the same.

The consumption or after effect of nickel nanoparticles was an increase in the levels of the free radical along with increased inflammation and oxidative stress.

Why Nanoparticles Are Useful More Than Ever

It is due to their size and capability of carrying important material through the bloodstream that the scientific industries have seen an increase in the applications of nickel nanoparticles. Since these particles can easily surpass any biological barriers, which is why they have been used in supplying medicine. Just like nickel nanoparticles, the iron oxide nanoparticles are also used in various biomedical purposes. Though the benefit of using iron oxide is conceded to be better due to its non toxic properties against human usage. Since iron oxide nanoparticles are found to be useful in various biomedical applications, it is considered important in vivo applications as well.

An important use of iron oxide: Iron oxide has been found helpful in conducting magnetic nano therapy for cancer treatments as well. Iron oxide nanoparticles are unstable particles due to their very extensive surface to volume ratio. Due to which these particles also tend to lose their magnetism and dispersity.

But the combination of the above two has resulted in giving the biomedical industry some solutions too. According to a research at NCBI, bimetallic nickel-iron nanoparticles are being used for decontamination of groundwater. Wherein when the bi-metallic nanoparticles, when compiled together, create a reactive material which is supposed to help degrade the levels of TCE or chlorinated hydrocarbons in groundwater.

There is much to be studied about nanoparticles in dept. We have tried to cover a surface level information about the toxicity of these nanoparticles and how these are revolutionizing not just the medical field but other industries too.
