Colloidal photonic glasses offer an appealing way to produce vivid colors without any chemical dyes—but so far, a stubborn optical effect has long prevented them from generating a true red color. Now, Yuwon Jeon and colleagues ...
Osaka Metropolitan University researchers have developed a light-driven technique that quickly amasses thousands of bacteria into a single spot, boosting detection speed and sensitivity. Their approach paves the way for earlier ...
Complexity may seem subjective, but a quantitative measure of the complexity of nanomaterials was recently developed by a team of researchers from the University of Michigan Engineering, the University of Southern California ...
Gold has been prized for thousands of years for its enduring shine, but Tulane University researchers have discovered that gold's resistance to tarnishing depends on more than its chemistry.
Gold nanoparticles, which are about one-thousandth the width of a human hair, can convert light they receive from a laser into heat. This capacity, known in medicine as photothermal therapy, is effective at destroying cancer ...
The task of gently transporting a microscopic particle from one point to another along a winding path, and then bringing it back using nothing more than a single, compact chip is a challenge we set out to address in our new ...
When inorganic nanoparticles come together, their optical, electronic, and magnetic properties depend strongly on how they are arranged. Being able to reorganize these arrangements in a controlled way could therefore provide ...
Researchers at the National University of Singapore (NUS) have developed a high-throughput method to identify gold nanoparticles capable of delivering therapies directly to mitochondria (the energy centers inside cancer cells). ...
Today, I want to walk you through a deceptively simple innovation from the lab at Loughborough University (PI: Prof Marco Peccianti): what happens when we decorate a spintronic heterostructure with a sparse layer of plasmonic ...
A team led by scientists at the National Graphene Institute (NGI) at The University of Manchester has developed the first technique capable of capturing atomic‑resolution videos of individual gold atoms 'dancing' across a ...
