Nanoscale Imaging Helps Understand Antimicrobial Peptide Interaction at the Molecular Level

The ever-increasing threat from “superbugs” – strains of pathogenic bacteria that are impervious to the antibiotics that subdued their predecessor generations – has forced the medical community to look for bactericidal weapons outside the realm of traditional drugs. One promising candidate is the antimicrobial peptide (AMP), one of Mother Nature’s lesser-known defenses against infections, that kills a pathogen by creating, then expanding, nanometer-sized pores in the cell membrane until it bursts. However, before this phenomenon can be exploited as a medical therapy, researchers need a better understanding of how AMPs and membranes interact at the molecular level.

New Method Virtually Eliminates External Contamination in Graphene

Dr. Cory Dean, assistant professor of physics at The City College of New York, is the lead author of a paper published November 1 in the journal “Science” that demonstrates it is possible for an atomically thin two-dimensional (2D) material to have electrical contact along its one-dimensional (1D) edge. The contact architecture offers a new assembly technique for layered materials that prevents contamination at interfaces.

Georgia Researchers Develop High-Performance Barrier Films Using Atomic Layer Deposition

A new type of "good cholesterol," made in the lab, could one day deliver drugs to where they are needed in the body to treat disease or be used in medical imaging, according to scientists. Their report on the high-density lipoprotein (HDL) mimic, which is easy to make in large amounts, appears in the journal ACS Nano.

Researchers Study how Bacteria Create Magnetite Nanoparticles Using MamP Protein

By the time people began to look for viable routes on the ocean with the help of a compass needle in the 12th century, magnetic navigational aids had already long been in use by other living creatures. Migratory birds orient themselves with respect to the Earth’s magnetic field, but some unicellular organisms, called magnetotactic bacteria, do as well. They carry within them a chain of nanoparticles of magnetite, a magnetic mineral that functions as an internal compass.
