Tiny displacements, giant changes in optical properties

Tiny displacements, giant changes in optical properties

In a study published recently in Advanced Materials, researchers from Washington University and the University of Southern California reveal a new pathway for designing optical materials using the degree of atomic disorder. The researchers anticipate developing crystals that enable advanced infrared imaging in low-light conditions or to enhance medical imaging devices.

Smart nanoparticles may be able to deliver drugs to heart after heart attack

Jianjun Guan, a materials scientist in the McKelvey School of Engineering at Washington University in St. Louis, received a four-year more than $2 million grant from the National Institutes of Health (NIH) to design a system of nanoparticles that deliver drugs after a heart attack much more effectively than current methods allow.

Imaging technique shows new details of peptide structures

In a paper published in ACS Nano, researchers at Washington University in St. Louis outline how they used a chemical probe to light up interlocking peptides. Their technique will help scientists differentiate synthetic peptides from toxic types found in Alzheimer’s disease.
