TiO2/ZnO as in cosmetic products, SWCNT and MWCNT as in water purification products.

The functionalization of carbon nanotubes is commercially available now. The synthesis of the MWNTs by Chemical Vapor Deposition is cheaper than other years. Regards!

Santos and Yoxkin,

Thank you for your response. Do you both know of an article that supports your claims?

I don't know if is possible say some company's name that sell carbon nanotubes, but the multi-walled carbon nanotubes by CVD are commercially available because we have bought them. Best regards.

The aplication, maybe some papers can you to help:

Hi Santosh,

Thank you for your response. I appreciate it.

Al2O3, ZnO and TiO2 nanoparticles because of their cost is much lower than pure metallic nano-particles. Most of the research scientists used/synthesized these ananoparticles and you will get all of data and thermophysical properties of these particles.

Application includes heat transfer (in the form of nanofluids and drug delivery). rest of the applications you can Google it.

You can synthesize by YOUR self, it is relatively easy, one advanced protocol is presented in this publication:

Article Magnetic Gold Nanoparticles in SERS-Based Sandwich Immunoass...

The classic ones Aerosils and related Metal oxides from former Degussa, now Evonik. Not to forget carbon blacks.

Thank you for all the response.

Arunas, if I do synthesize using your process, will there be infringement of IP when the magnetic AuNPs are used commercially? Do you own the IP?

Some companies are producing nanomaterials commercially like ZnO, TiO2, Al2O3. That can be applied for applications depending upon property wise. Otherwise you can derive nanomaterials from waste materials, for example, making CaO nanomaterials from chicken egg waste shell materials, snail shells etc.,

if you want silica nanomaterials you can derive from rice husk, baggase waste materials. this kind of derived nano materials is more cheap compared to purchasing thing.

Nano alumina(AEROXIDE) and nanosilica (AEROSIL) from Evonik Industries.

You can see the link : http://corporate.evonik.com/en/products/products-in-the-web/Pages/default.aspx

Nano TiO2, ZnO also commercially available.

Nano Diamond also available.

MWCNT, SWCNT, DWCNT,GRAPHENE are commencially available with

Thank you all for your responses.

Baskar and Saronjini, are there any references to these? Please add them here when you can. Thank you.

It does seem like CNTs have the highest commercial applications today. These are also one of the most versatile nanomaterials and the most commercially available among the various commercialized nanomaterials.

Dear Zoraida,

this is far from being true, only if you neglect traditional nanoparticle products - carbon black, aerosil, fumed metal oxides, nanosized titania and ZnO.

Titus, can you explain why you said the above about nanosized titania and ZnO? You are right, I am excluding the traditional ones.

beside the traditional Aeroxide P (titania) special nanosized titania and zinc oxide is used in suncare products. The first also in paints and in food as pigment.

Titus, nanosized TiO2 and ZnO2 are also synthesized now...

Dear Zoraida the most widely nanoparticles used in food packaging are nanoclays to reinforce plastic films and make them more impermeable to oxygen, nanoTiO2 for its antimicrobial activity which needed of UV light, nanoZnO like antimicrobial which no needed of UV light, nanosilver like antimicrobial, Chitosan a biopolymer used for encapsulation of nutraceuticals and for its antimicrobial activity, nanogold in time-temperature indicators in food and medicine distribution. These are few example of potential application of nanoparticles in food packaging.

Examples of nanopolymers on the market today are: imperm ® (Nanocor and Mitsubishi Gas Chemical Alliance), Aegis ® OX (Honeywell) and Duretham ® LDPU 601. Imperm ® can be used in multi-layer PET bottles of beer and other carbonated beverages in order to reduce the loss of CO2 and the entry of outside air inside, increasing the shelf life but Reg ° 10/2011 has banned the use for sanitation issues, while Duretham is a transparent plastic film made ​​from nylon enriched with particles of silicates, which make it more rugged and waterproof, finally Aegis hybrid is a plastic based on polyamide and silicates that is chosen when the normal nylon is too permeable and the lining with EVA is too expensive.

definitely, carbon black is the most widely used nanomaterial, since times during which nobody called them "nano".

I can add one newer nanomaterial: an Organic Nanometal (chemically "polyaniline"), you can find all references here:

http://www.bernhard-wessling.com

then go to "history" or even better to "milestones & highlights" using the navigation.

many relevant papers can also be found here on my RG page.

There has been a very excellent exchange of ideas provided. Thank you for all your response. Is there anyone who can lead me to the uses and applications of liposomes? iron oxides? polymers?

Conductive polymers (in my case: Organic Metals) are insoluble, infusible and are composed of 10 nm small primary particles which are the smallest conductive unit which also exhibit all the other unique properties (like: catalytic capabilities).

Hence these are also nanomaterials, and they are processed as dispersions (colloids).

You can find a lot of publications on my RG page, or here:

www.bernhard-wessling.com

www.bernhard-wessling.com/pani

Major application for these are final finishes on printed circuit board (in big mass production scale),

and in smaller scale, still embryonal: corrosion protection (because of their powerful passivation capability)
