Scanning tunneling microscope image of wide-band metallic graphene nanoribbon (GNR). Each cluster of protrusions corresponds to a singly-occupied electron orbital. The formation of a pentagonal ring near each cluster leads to a more than tenfold increase in the conductivity of metallic GNRs. The GNR backbone has a width of 1.6...
Peidong Yang, S.K. and Angela Chan Distinguished Professor of Energy and Professor of Chemistry, has been recognized as one of three laureates of the 2020 Global Energy Prize for the pioneering invention of nanoparticle based solar cell...
Markita Landry and UC Berkeley recently filed patents on a new nanotube technology to delete genes in crop plants without the risk of inserting new genes. Editing the genome of crop plants can boost such traits as disease resistance or drought tolerance. Since the new process adds no genes to the plant genome in the editing process, it conforms to non-GMO requirements in the U.S. and several other countries outside Europe.
From water bottles and food containers to toys and tubing, many modern materials are made of plastics. And while we produce about 110 million tons per year of synthetic polymers like polyethylene and polypropylene worldwide for these plastic products, there are still mysteries about polymers at the atomic scale.
Protein-like molecules called “polypeptoids” (or “peptoids,” for short) have great promise as precision building blocks for creating a variety of designer nanomaterials, like flexible nanosheets – ultrathin, atomic-scale 2D materials. They could advance a number of applications – such as synthetic, disease-specific antibodies and self-repairing membranes or tissue – at a low cost.Scientists at Berkeley Lab are the first to use cryogenic electron microscopy (cryo-EM) to image atomic changes in artificial proteins known as “peptoids.” Their findings have implications for the synthesis of soft, 2D materials for a wide variety of applications.

Lieber are the 2019 recipients of the prestigious Robert A. Welch Award in Chemistry. Highly-respected and influential leaders in the fields of nanoscience and nanotechnology, Drs. Alivisatos and Lieber are being recognized for their important research contributions which have had a significant, positive impact on humankind.
By using nanomaterials to create new tools, Markita Landry reckons she can crack open new areas of science. Landry, an assistant professor of chemical and biomolecular engineering at the University of California, Berkeley, is harnessing the chemical and physical properties of nanomaterials to do things like deliver DNA to plants and measure signaling molecules in the brain.
A new technique developed by University of California, Berkeley, nanomaterials scientists has overcome the overcome the obstacles to delivering macromolecules using inexpensive lab equipment to efficiently infuse large macromolecules into cells. Called nanopore-electroporation, or nanoEP, the technique gently creates fewer than a dozen tiny holes in each cell that are sufficient to let molecules into the cell without traumatizing it. The pores heal rapidly afterward. In tests, more than 95 percent of the cells survived the procedure. .
New research reported from the lab of Markita Landry announces scientists could make genetically engineering any type of plant—in particular, gene editing with CRISPR-Cas9—simple and quick. To deliver a gene, the researchers grafted it onto a carbon nanotube, which is tiny enough to slip easily through a plant’s tough cell wall. To date, most genetic engineering of plants is done by firing genes into the tissue—a process known as biolistics—or delivering genes via bacteria. Both are successful only a small percentage of the time, which is a major limitation for scientists seeking to create disease - or drought-resistant crops or to engineer plants so they’re more easily converted to biofuels.
