CSN Scientists develop new benchtop reactor for nanoparticles

  • News

In a paper just published in ACS Nano, CSN researchers Sam Lohse and his mentor, Catherine Murphy, describe a new benchtop reactor system that can be used for high-throughput functionalization of nanoparticles with different sizes and shapes.  In initial tests the reactor has been used to make gram-scale quantities of gold nanospheres and nano-rods in a highly reproducile, automated manner.  The reactor design should also be applicable to other types of metallic nanoparticles such as silver and copper.  The reactor enables synthesis of large batches of identically functionalized nanoparticles that can then be distributed to other researchers. The new work will enable scientists to replicate one another's work and will enhance our ability to understand how nanoparticles interact with the environment.

CSN at the Engineering Expo!

We have developed an educational activity centered around our fluorescent nanodiamonds! Madison-based CSN scientists will be assisting schoolchildren and the general public with this activity at this year's Engineering Expo in Madison, WI Thursday, Friday, and Saturday April 18-20. Can't make it to Madison? Stay tuned on our blog, sustainable-nano.com, for an upcoming post where you can see the activity!

CSN on Minnesota Public Radio

Minnesota Public Radio has just published an article about our nanotechnology and the environment featuring interviews with Center for Sustainable Nanotechnology Investigator Christy Haynes and Center Director Bob Hamers.

Franz Geiger is elected a Fellow of the AAAS

Congratulations to Franz Geiger for being elected a Fellow of the American Association for the Advancement of Science (AAAS), the world’s largest general scientific society. Franz is being honored for his distinguished contributions to unraveling important yet previously unidentified molecular aspects of environmental interfaces, including atmospheric aerosols and geochemical surfaces, using non-linear, laser-based spectroscopy. Franz and the other new AAAS Fellows will be honored Feb. 16 at the 2013 AAAS Annual Meeting in Boston.

Christy Haynes awarded New Orleans Kavli Foundation Emerging Leader in Chemistry Award

Congratulations to Christy Haynes on being awarded the New Orleans Kavli Foundation Emerging Leader in Chemistry Lecture!  Christy was one of 13 candidates submitted by 9 divisions and was nominated by the Analytical Division of the ACS.  Christy will deliver her award lecture, "Biological and ecological toxicity of engineered nanomaterials" at the American Chemical Society National Meeting on April 8, 2013.

Center for Sustainable Nanotechnology funded by NSF

The National Science Foundation has funded the Center for Sustainable Nanotechnology beginning September 15, 2012 ! The CSN is a multi-institutional partnership devoted to investigating the fundamental molecular mechanisms by which nanoparticles interact with biological systems. More information about the CSN can be found in the "about" section of this site.
