Just one dose of a new nanoparticle-based COVID-19 vaccine was enough to produce an immune response in animals on track with vaccines currently in clinical use. And with minor changes, Northwestern University investigators hope the same vaccine platform could target other infectious diseases.
In a new study, published in PNAS, 100 percent of mice who received the protein-based immunization survived when challenged with lethal doses of the SARS-CoV-2 virus, which causes COVID-19. None of the mice experienced lung damage due to SARS-CoV-2 exposure, and all mice who did not receive this nanoparticle vaccine died in a 14-day trial… Continue reading.

An early clinical trial in individuals with the deadly brain cancer, glioblastoma, showed an experimental spherical nucleic acid (SNA) drug developed by Northwestern University scientists was able to penetrate the blood-brain barrier and trigger the death of tumor cells.
This is the first time a nanotherapeutic has been shown to cross the blood-brain barrier when given through intravenous infusion and alter the genetic machinery of a tumor to cause cell death. The drug crossed the blood-brain barrier, dialed down the level of a cancer-causing gene and promoted tumor cell death… Continue reading.
Complex crystals that mimic metals—including a structure for which there is no natural equivalent—can be achieved with a new approach to guiding nanoparticle self-assembly.
Rather than just nanoparticles that serve as “atom equivalents,” the crystals produced and interpreted by Northwestern University, University of Michigan and Argonne National Laboratory rely on even smaller particles that simulate electrons.
“We’ve learned something fundamental about the system for making new materials,” said Northwestern’s Chad Mirkin, the George B. Rathmann Professor of Chemistry in the Weinberg College of Arts and Sciences and a co-corresponding author of the paper in Nature Materials. “This strategy for breaking symmetry rewrites the rules for material design and synthesis… Continue reading.
Northwestern investigators have identified a novel approach to control the hierarchical assembly of protein pathways with DNA, according to a study published the Proceedings of the National Academy of Sciences (PNAS).
The approach may facilitate the construction of synthetic protein materials, which can be used for a variety of medical and scientific purposes.
“Hierarchical assembly methods are transformative because the structure of the final material is dictated by the information programmed into each individual building block,” said Chad Mirkin, Ph.D., professor of Medicine in the Division of Hematology and Oncology, the George B. Rathmann Professor of Chemistry at Northwestern’s Weinberg College of Arts and Sciences, and lead author of the study… Continue reading.
A new immunotherapy developed by researchers at Northwestern University dramatically extends the survival time of mice with triple-negative breast cancer, one of the most aggressive and difficult-to-treat forms of breast cancer.
In a new study, mice treated with the therapy, which comprises two immunity-boosting drugs housed inside a nanoparticle, experienced complete tumor remission for at least 100 days. All untreated mice died by day 30. None of the treated mice experienced adverse side effects or autoimmune responses.
The nanoparticle, called a spherical nucleic acid (SNA), is a globular form of DNA that can easily enter and stimulate immune cells. Northwestern’s Chad A. Mirkin, who led the study and invented SNAs, credits the nanoparticle’s shape and structure for the immunotherapy’s success… Continue reading.
Researchers hope to make a dent in hospitals’ need with a single 3D printer
Northwestern University researchers have demonstrated the ability to generate 1,000 components for face shields per day — with a single 3D printer.
A critical piece of personal protective equipment (PPE), face shields protect health care workers from the novel coronavirus (COVID-19) as they treat patients.
When Northwestern researchers Chad A. Mirkin and David Walker heard about the PPE shortage in hospitals, their team sprang into action. In October, Mirkin and his research group, in a breakthrough article in the journal Science, unveiled a new 3D printing technique called “high-area rapid printing” (HARP), a 13-feet-tall printer with a 2.5 square-foot print bed that can print about half a yard in an hour — a record throughput for the 3D printing field… Continue reading.

Different eras of civilization are defined by the discovery of new materials, as new materials drive new capabilities. And yet, identifying the best material for a given application — catalysts, light-harvesting structures, biodiagnostic labels, pharmaceuticals, and electronic devices—is traditionally a slow and daunting task. The options are nearly infinite, particularly at the nanoscale where material properties — optical, structural, electrical, mechanical, and chemical — can significantly change, even at a fixed composition.
A study published this week in the Proceedings of the National Academy of Sciences (PNAS) supports the efficacy of a potentially revolutionary new tool developed at Northwestern University to rapidly test millions — even billions — of nanoparticles to determine the best for a specific use.
“When utilizing traditional methods to identify new materials, we have barely scratched the surface of what is possible,” said Northwestern scientist Chad A. Mirkin, the study’s corresponding author and a world leader in nanotechnology research and its applications. “This research provides proof-of-concept — that this powerful approach to discovery science works… Continue reading.
