Gold nanoparticles (AuNPs) are nanoscale particles of gold, typically ranging in size from 1 to 100 nanometers (nm). These nanoparticles exhibit unique physical, chemical, and optical properties that ...

Nanoparticles, typically defined as particles between 1 and 100 nm in at least one dimension, have emerged as potent antibacterial agents through mechanisms such as membrane disruption, generation of ...

Nanoparticles exhibit distinct physical and chemical properties compared to bulk materials, making them valuable in applications such as electronics, photovoltaics, catalysis, and biomedical sciences.

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, ...

The sol-gel process is a widely used method for synthesizing nanoparticles with precise control over size, shape, and composition. This method converts a liquid precursor, or "sol," into a solid gel ...

Nanodiamonds are tiny diamond particles only a few nanometers in size. Because they are chemically highly stable and can host ...

Using finely tuned nanoscale building blocks, researchers from Brown University and the University of Michigan College of ...

Composed of five or more elements in nearly equal amounts, high-entropy alloys (HEAs) have emerged as promising catalysts due to their compositionally complex surfaces that can accelerate chemical ...
