We engineer RNA networks that enable living cells to detect intracellular RNA molecules and perform computations.
Welcome to the website of the Green lab in the Biomedical Engineering Department at Boston University.
Our group pursues highly interdisciplinary research at the interfaces of chemistry, biology, and materials science. Much of this work exploits programmable molecular interactions between nucleic acids and proteins to direct the assembly of nanometer-scale organic and inorganic components and to construct information-processing circuitry inside living cells. These efforts have wide-ranging implications for biotechnology, medicine, biosensing, and nanotechnology.
We develop low-cost portable diagnostics that can be used to detect pathogens in low-resource settings.
We develop new antimicrobial materials that are active against broad classes of drug-resistant bacteria and fungi.
We produce and chemically modify two-dimensional materials with novel electronic, optical, and mechanical properties.
Researchers from the Green lab at Arizona State University have reported a highly specific method for detecting point mutations. The technique can be applied in living cells and paper-based diagnostic tests, offering a rapid, highly accurate and inexpensive means of identifying mutations relevant to human health. The work is published in Cell. (ASU Biodesign story)
Scientists at the University of Toronto and Arizona State University have developed the first direct gene circuit to electrode interface by combining cell-free synthetic biology with state-of-the-art nanostructured electrodes. The work is published in Nature Chemistry. (ASU Biodesign story)
The Green lab at ASU’s Biodesign Institute and scientists from the Wyss Institute for Biologically Inspired Engineering and Northwestern University are carrying RNA’s startling capacities further by designing sophisticated RNA circuits that can perform a variety of computer-like logic tasks within living cells. (ASU Biodesign and ASU Now story)
Programmable repressor elements expand the toolbox of synthetic biologists, enabling more sophisticated and accurate diagnostic, environmental, and biofabrication approaches. The work is published in Nature Chemical Biology. (Wyss Institute story)
