Studies from School of Chemical Sciences Have Provided New Information about Nanocrystals (Aligned cellulose nanocrystals and directed nanoscale deposition of colloidal spheres)

By a News Reporter-Staff News Editor at Life Science Weekly -- Investigators discuss new findings in Nanocrystals. According to news reporting out of Stockholm, Sweden, by NewsRx editors, research stated, "Cellulose nanocrystals are aligned in wrinkled polydimethylsiloxane templates and transferred to polyethyleneimine-coated silica surfaces in a printing process similar to microcontact printing. The highly aligned nanorods were deposited onto the surfaces with a line-to-line distance of 225-600 nm without loss of alignment."

Our news journalists obtained a quote from the research from the School of Chemical Sciences, "It was also possible to repeat the transfer process on the same surface at a 90-degree angle to create a network structure. This demonstrates the versatility of the technique and creates more options for advanced multilayering of materials. To demonstrate that the surface properties of the anionic cellulose nanorods were unaffected by the transfer process and to prove the concept of functionalizing transferred particles, cationic latex particles were electrostatically self-assembled onto the cellulose nanorods."

According to the news editors, the research concluded: "The directed deposition of these particles resulted in excellent site specificity and the highest resolution to date for controlled deposition of colloids on an electrostatically patterned surface."
