Five CBES researchers land on ‘highly cited’ list
CBES Director Samuel Stupp and investigators Chad Mirkin, George Schatz, Joanna Aizenberg and George Whitesides were named to the Highly Cited Researchers 2019 list by the Web of Science Group. The list sought to recognize the world’s most influential researchers of the past decade, as evidenced by having multiple papers that ranked in the top 1 percent of citations for their field and year.
Weiss leverages quantum mechanics to produce desirable bioactive molecules
CBES investigator Emily Weiss led a team of researchers who used visible light and tiny nanoparticles known as quantum dots to make molecules of a class that is highly desirable for drug development. The nanoparticle catalysts — only three nanometers across — can be reused for additional chemical reactions, and the work represents the first use of a nanoparticle’s surface as a template for a light-driven reaction called a cycloaddition.
“Quantum dots behave more like organic molecules than metal nanoparticles,” Weiss said. “The electrons are squeezed into such a small space that their reactivity follows the rules of quantum mechanics. We can take advantage of this, along with the templating power of the nanoparticle surface.”
Mirkin receives Netherlands Award for Supramolecular Chemistry
CBES investigator Chad Mirkin accepted the 2019 Netherlands Award for Supramolecular Chemistry on August 18 during the International Conference on Molecular Systems Engineering in Nijmegen. The award, given by the Research Center for Functional Molecular Systems, seeks to “recognize and reward outstanding scientists in the supramolecular chemistry field.”
As the third recipient of the honor, Mirkin joins two Nobel Laureates in chemistry: Jean-Marie Lehn and Sir Fraser Stoddart. Mirkin also visited universities around the Netherlands as part of a lecture series associated with the award.
Danna Freedman honored with Presidential Early Career Award
CBES investigator Danna Freedman is one of five Northwestern University professors selected for the Presidential Early Career Award for Scientists and Engineers (PECASE). President Donald Trump announced the recipients on July 2, and each awardee will be recognized at a July 25 ceremony in Washington, D.C.
Freedman, a chemist nominated by the National Science Foundation, received the PECASE for her work on qubits — the smallest unit in quantum computing. Developing computers with these objects would allow scientists to understand electron transfer in new ways, enabling the creation of novel materials for renewable energy.
Joanna Aizenberg elected to prestigious national academies
CBES investigator Joanna Aizenberg was elected to the National Academy of Engineering in February and to the National Academy of Sciences in April. The NAE honor recognizes individuals who have made outstanding contributions to engineering research, practice or education.
For her NAS election, Aizenberg was cited for "being the pioneer of the budding field of bioinspired materials chemistry, applying lessons from natural systems to inventing artificial materials with unprecedented properties." She was also noted for making "groundbreaking, seminal contributions to biomineralization, crystal engineering, smart surfaces, and antifouling and stimuli-responsive materials that display unique hierarchical designs."

New paper details how to fabricate optically active structures
Northwestern University researchers, including CBES senior investigator Chad Mirkin, have developed a first-of-its-kind technique for creating entirely new classes of optical materials and devices that could lead to light bending and cloaking devices.
Using DNA as a key tool, the interdisciplinary team took gold nanoparticles of different sizes and shapes and arranged them in two and three dimensions to form optically active superlattices. Structures with specific configurations could be programmed through choice of particle type and both DNA-pattern and sequence to exhibit almost any color across the visible spectrum.
