Nanotech 2010 Conference and Expo – Summary (Part I)

NSTI Nanotech 2010 ( TechConnect World 2010) took place in Anaheim, CA, USA, in June 2010. It is the primary industry event on nanotechnology and clean technology in the world. The event were organized by The Nano Science and Technology Institute (NSTI; http://www.nsti.org).

In this issue, we will begin to introduce single companies, poster sessions and general impres- sions. Dozens of new products and technologies were unveiled on the show. Here are some examp- les:

H. Pham, F. Li, J.B. Goh, J. Dinglasan, D. Anderson from Vive Nano, Inc., CA, demonstrated in the session “Nanoparticles in Soft Materials, Colloids” with their presentation “Polymer nanoparticles as nanoformulation agents” an approach to produce polymer nanoparticles with tailored characteristics to accommodate different nanoformulation appli- cations.

Polymer nanoparticles are made from the collapse of polyelectrolytes in the presence of counterions and/or different solvents. The size, hydrophobic/

hydrophilic character, as well as surface interaction characteristics of collapsed polyelectrolyte nano- particles can be controlled by varying the degree of crosslinks and the degree of chemical modification of the parent polyelectrolyte chain. Depending on the characteristics of the polymer nanoparticle (i.e. size, hydrophobic/hydrophilic character, degree of cross- linking, etc.) different molecules like dyes, pigments, agricultural and pharmacological active ingredients, and aromatics can be loaded into the polymer nano- particles. Polymer nanoparticles made with this approach are typically smaller in size (10 to 50nm) than those achievable using other methods. Data illustrating the different characteristics of the poly- mer nanoparticles such as hydrophobic/hydrophilic character, size, and the interactions of the polymer nanoparticles with different substrates were presen- ted.

In April 2010, Vive Nano has been selected to recei- ve Frost & Sullivan’s 2010 North American Technolo- gy Innovation of the Year Award for its unique encap- sulation technology to synthesize nanoparticles. After evaluating the field of competing technologies, Frost & Sullivan was impressed by Vive Nano’s flexible process based on the principle of polymer collapse,
