Indeed, these nano zinc oxides have amazing properties and these properties do distinguish them from other compounds as well. For instance, one of the main properties of these nanoparticles is their surface area. If we take into consideration the overall surface area of these particles, then these have got a relatively large surface area, and this large surface area is basically compared to their sizes. These nanoparticles have a much larger surface area when we compare it to that of their specific size and this is one of the main aspects that explain their chemical properties such as their act as an efficient catalyst. As this oxide has molecules having a large surface area, then it definitely improves their catalytic activity and because of this property, it is said that nano zinc oxide has high catalytic activity.

Furthermore, if we talk about some of the other properties of these zinc oxide nanoparticles, then these properties are basically based on the method or the way in which these are synthesized. As these nano zinc oxides are synthesized in different ways, so we can say that each different synthesis method for this compound results in different properties and characteristics of this compound.

Their importance and usage could be easily understood by looking at the aspect that these zinc oxide nanoparticles are indeed one of the most manufactured nanomaterials. This zinc oxide nanomaterial basically comes in the top three most manufactured and produced nanomaterials and therefore, we can make an idea about its importance and usage. Further, if we consider the other two most-produced nanomaterials, then these basically include the titanium dioxide nanoparticles, and the silicon dioxide nanoparticles are also in the same list. So, these three are indeed the most widely used and the most manufactured nanomaterials that exist.

What are some of the uses of these nano zinc oxide? What is the overall use of this zinc oxide nanomaterial? How can we make use of these zinc oxide nanoparticles?

If we basically talk about zinc oxide, then it is generally an inert white compound and this inert compound is indeed widely used as an agent for bulking and filling purposes. Also, this zinc oxide has prominent uses as a white pigment as well. However, its use is not limited to this only rather, apart from being used as a bulking and filling agent, this zinc oxide is also utilized in cosmetics as well as medical products.

What are some of the properties of nanoparticles? How can we say distinguish that nanoparticles of the same material can differ from the larger particles? Is this phenomenon true in the case of zinc oxide? What makes this nano-form of zinc oxide more unique and distinguished?

Indeed, we can say that there can be some distinguished differences present in the nanoparticles when compared to the larger particles of that same material. These differences can either be physical or chemical-based and if we take into consideration the nano zinc oxide that is used in the sunscreens, then what I would say is that various tests have been performed on these particles. These tests were physical and chemical as well. The results of these tests were quite distinguishing. If we talk about the overall structure of the small or nano-sized zinc oxide and the large zinc oxide, then these had almost exact crystal structure as well as the same ranges of shape. Apart from this, most of the other physical and chemical properties of these different-sized compounds were also the same but at one point a variation came and this was basically regarding the solubility. If we see the main difference between the normal-sized zinc oxide compared to that of the nano-sized zinc oxide, then it was regarding the solubility of these compounds that make them different from each other. The nano-form of zinc oxide is actually more soluble and has a greater solubility ratio when a comparison is made with respect to its normal form. So, this is the main difference between these two form gradients.

Has the safety of nano zinc oxide been tested? If yes, then how have these tests been performed? How did these toxicology evaluations take place? What were some of the results of these tests?

Indeed, various kinds of tests have been conducted and different toxicological evaluations also took place. Well, if we take into consideration the main tests, then these included the tests from skin irritation, internal exposure, ingestion, respiration as well as direct injection. So, these were the basic tests that had been conducted in order to check for the toxicology of nano zinc oxide. These tests were mainly regarding the harm that these zinc oxide particles may cause when these are used in sunscreens and another important aspect is that most of these tests were performed on animals.

Now, if we talk about the results of these tests, then these were indeed quite convenient. These acute toxicity tests mostly provided us with the results of no illness. Although some tests did show a kind of illness when compared on the large scale or in a larger context, these tests showed no illness. Tests regarding skin irritation, allergies, and skin sensation were also conducted but still, the results to a much larger extent were normal.  Although some tests depicted some mild irritations but still, overall, the results were quite convincing and normal. So, these were the overall results of these tests that were conducted for determining the toxicity of oxide of zinc.

Is there any chance or probability that the nano zinc oxide can cause any damage to the DNA of an individual? Can these nano-sized zinc oxide particles cause any changes or damage to the chromosomes of an organism?

Well, what I would refer to or say is that various tests have been conducted on different species of organisms regarding the effect that whether any damage can be caused because of the nano-sized zinc oxide particles, but the results didn’t show any such signs. Further, scientists have not been able to gather any kind of evidence in this regard. No conclusive evidence has been gathered regarding the damage that is caused by the nano zinc oxide on the DNA or the chromosomes of an organism. But what is concluded mostly based on the research is that indeed no zinc oxide can actually pass through the skin and apart from this, there are indeed negligible chances of this oxide causing any damage to the DNA or the chromosomes of an organism.

Therefore, based on the above-stated experimentation and statements, what has been concluded is that the nano zinc oxide does not cause harm and damage to any extent to the DNA and chromosomes of an organism.

This surely is considered to be the main obstacle in its way regarding its use in cosmetics especially.

I want to know that can these zinc oxide nanoparticles pass through the pores of the skin? Can these nano zinc oxides penetrate through the skin of an organism? What is the overall probability of this penetration?

Well, if we consider it in a broader aspect, then particularly, these nano zinc oxide can penetrate through the epidermis but on a very small scale. A large number of clinical tests had been conducted accordingly and the results depicted that indeed, a very small amount of these nanoparticles penetrated through the skin, and apart from this, these nanoparticles were insoluble form. Apart from this, another aspect is that these nanoparticles that penetrated through the skin were of quite a low level. Indeed, the level was low to such an extent that this level was even lower than the body’s normal zinc levels. Therefore, it has been concluded based on these clinical tests that the nano zinc oxide can do penetrate the skin but at extremely low levels and further, such low levels of nano zinc oxide are not harmful at all.

Do sunscreens use nano zinc oxide? Are these sunscreens safe to use? Do these sunscreens cause any damage to the skin of an individual? Is it reliable to use sunscreens that have nano zinc oxide in them?

As we have already discussed that the nano zinc oxide is indeed present in sunscreens and the main reason behind their presence in sunscreens is that firstly, they provide the white color to the sunscreen, and secondly and most importantly, they protect the skin from harmful ultraviolet rays. Nanoparticles of this oxide have the ability to absorb the ultraviolet rays and this absorption of ultraviolet rays is basically helpful for individuals. Therefore, these sunscreens are very beneficial for the overall skin still taking into account the fact that they contain nano zinc oxide.

If you apply these sunscreens on your skin, then these sunscreens that contain nano zinc oxide in them are absolutely safe to use but do not ingest such sunscreens because ingestion of such nano zinc oxide containing sunscreens can cause some internal damage. Therefore, as long as you apply these sunscreens containing zinc oxide nanoparticles externally, they are safe to use.
