Nanotechnology has become a hot topic in the world of industry in recent years, as companies come up with applications where nanoparticles can make an impact. One such area is in printing, where nanotechnology can impart new qualities to the product, whether it is conductivity, electromagnetic shielding, transparency or countless other characteristics.

Dr. Tapesh Yadav, chairman and CEO of NanoProducts Corporation, has studied nanotechnology since the early 1990s, and he sees the opportunities nanotechnology offers.

“We formed our company in 1994 after I graduated with my Ph.D. in chemical engineering from Massachusetts Institute of Technology,” Dr. Yadav said. “I had done my thesis on carbon nanotechnology, and during my research, my interest in nanoscale technology grew.”

After graduating from MIT, Dr. Yadav developed NanoProducts Corp. with an eye toward developing and commercializing nanomaterials and related nanotechnology in commercial quantities and at cost-effective prices.Since its founding, NanoProducts Corp. has developed numerous products. Currently producing nanoscale materials in commercial quantities, NanoProducts owns 35 issued and allowed patents, with more than 40 additional patents pending in the U.S. and worldwide.

In September, NanoProducts Corp. received a key nanotechnology patent from the U.S. Patent and Trademark Office relating to inks and dispersions.

“Inks are complex products, and their manufacture and use often require demanding technology for performance applications,” Dr. Yadav said. “While inks and dispersions are commonly used in a wide range of printing applications, they are also used in optics and electronics, device fabrication, drug delivery, product labeling, currency, high security, product tracing and authenticity applications. Often inks contain high performance additives, phosphors, magnetic, radiation-sensitive or other powders. Such applications often require complex powder additives and sophisticated ink and dispersion formulation technology.”

Dr. Yadav has been working with pigment companies to develop his inks and dispersions because of the characteristics the pigments impart.

“We started partnering with companies in pigment industries to compete with dyes because dyes fade with light and are unstable when exposed to chemicals,” Dr. Yadav said. “Nanotechnology is now successfully creating complex additives that are transparent like dyes and yet do not fade.”

Dr. Yadav said that NanoProducts’ inks and dispersions can be used in a wide variety of applications such as radio frequency identification (RFID) and conductive inks with silver or indium tin oxide, as well as active matrix liquid crystal displays, plasma displays, electroluminescent displays, organic light emitting displays, and field emission displays. He added that opportunities abound in traditional printing applications as well.

“Nanotechnology is the way printing will ultimately go, with particles so unique that they enhance consumer experience and deliver multifunctional performance,” he said. “Our focus is on high performance inks and dispersions, and it’s likely to grow into very significant opportunities.”
