Q:
From your perspective, which companies are creating the most innovative nanomaterials and nanotechnology products?
18 answers
Answers:
1. Bayer- carbon nanotubes, 2.Nanophos - paints and coatings and many others.Some nanotechnologists have developed treatments, coatings, paints, roof tiles, fabrics and other surfaces that can stay dry and clean themselves in the same way as the lotus leaf. 3. Sticky bandages inspired by Gecko’s feet could soon be used to seal wounds, I don't remember the company names.
~Shweta ST, Nanotech aspirant and Distributor of Nanotech products, Pune, India
We at KZI Consulting Inc. believe we have developed the strongest, most effective coatings for glass/windshields, fabric/textile and stone and we are less than one quarter the price of every product tested as of today.
~Mike K, President, Toronto, Canada

Q:
Please share with us any “non-standard” applications that nanomaterials and nanotechnology products have been used for.
16 answers
Answers:
1. I don't know about standardization of Ayurvedic medicines but old methods of production of ayurvedic medicine's powder produce few nanoparticles of particular material and useful for dissolving faster in blood and faster results too. 2. I have met a very senior chemical eng. with interests in ayurvedic preparation methods who now produces ayurvedic medicinal oils with excellent properties than that of bigger quantity of same medicine. It has low consumption 1 drop, 3times in a day to be put in mouth, reasonable rates and easy production of medicines. It uses nanofibres of particular material or medicine.

By mistake I spilled some of my own product, the stone sealant, on my bare foot and as I was applying a can of spray paint I sprayed my foot and it wiped off...wouldn't recommend putting on the body but it was definitely an interesting accidental experiment.

Q:
Do you know of any disastrous mistakes that occurred due to the incorrect usage of nanomaterials and nanotechnology products?
7 answers
Answers:
Yes, in the auto sector pre-treatment primer coatings are sometimes applied in error for the final coating! Hence keep each application color coded or clearly marked. Do not over-apply coatings. What we can't see causes damage and can be financially wasteful. Distractedness can cause problems: using incorrect smart fluids on specific surfaces.
~Dermott Reilly, Engineering Consultant, London, UK
Right now I do not know any but with time we will be able to have a case study. Maybe one example is the use of Gold NPs for medical devices, after the use of the test, how to recover the Au NPs or recycle it.
~Dr. David Jacob, Research & Development, Haifa, Israel
Yes, a company called Nanopool made people sick with their formulation when initially launched a few years ago in Europe...I think they got it fixed by now.

Q:
What would your design or feature "wish list" be for this product?
17 answers
Answers:
1. Don't have much info on CNTs now. 2. I have seen all desired properties for paints and coatings. Entrepreneurs find it difficult to find right team of technical people to guide them in their entrepreneurship journey. Being an owner of newly started venture for nanotech based products I have gone through those difficulties. Also money is like blood for business so VC fundings for nanotech ventures should be inspired. 3. Cost should be reasonable and the entrepreneurs / people should work on quality aspect of products.

Q:
Is there any advice you want to share with users to help them avoid common errors in selection or usage of nanomaterials and nanotechnology products?
12 answers
Answers:
Use a resource that is vendor neutral such as nanolandglobal.com where a wide field of experts and application experience can be utilized for the benefit of your specific nano project. Don't compromise on safety. Don't depend on the first website claiming to be an expert. Most are simply marketing companies with a nano focus.
~Dermott Reilly, Engineering Consultant, London, UK
You don't need very much product when applying...once coated move onto next area...there is no need to multi coat. If a spot or area is missed, it is easy to spot touch up as the nano molecules will bond to existing molecules.
~Mike K, President, Toronto, Canada
See the applications, it might happen that same properties can be obtained with the bulk, or it is most necessary to use them to get higher performance.

Buying AdviceTop

Q:
Do you have any advice for people relative to buying or using nanomaterials and nanotechnology products?
16 answers
Answers:
As per my knowledge every technology comes with its own merits and demerits. People working for good cause are higher than that working for bad causes, on this earth. So nanotechnology can bring revolution if used for good causes. Still one has to see the effects of nanoparticles on body, environment first and then promote the use of it. Money earning through business or anything should always be a second priority in one's life. One should speak to the manufacturers, senior scientists or knowledgeable people in this before taking any decision. e.g. Nanoparticles can penetrate the skin cells or human body cells also. So if comes in contact with body through cosmetics, textiles,etc. can prove hazardous. So one should chose the product very carefully or manufacturers should take all safety measures into consideration for employess, labour ,etc. We are part of nature and we should help to maintain environment. One should study topic "nanotoxicology and nanohazards" in wikipedia notes.

It's so early in the process, but finding the products that work best are so important. I applied a competitor's product on my windshield and it actually was a hazard rather than a safety improvement as the tinier water molecules didn't slide away and it made visibility slightly more challenging whereas my product greatly increases visibility especially in rainstorms/nighttime snow/slush conditions.
~Mike K, President, Toronto, Canada
Yes, find out who the real experts are in each specific area of application. No one company has all the research and experience in application, collaborate where possible, share and research. What works in one country does not necessary work in another where environmental conditions differ. Get trained up in application delivery
