Researchers have advanced smart coatings by manipulating nanoparticles to reconfigure themselves by using microscopy and computer simulation.
In a step towards developing smart coatings that can change color or other properties on the fly, researchers at the University of Michigan and Indiana University have successfully manipulated nanoparticles to reconfigure themselves.
The imaging technique allows researchers to observe how nanoparticles respond to changes in their environment in real-time, providing unparalleled insight into their assembly behavior. This device enabled the researchers to introduce various fluids into the cell in real time while observing the mixture under their electron microscope.
“You might have been able to move the particles into new liquids before, but you wouldn’t have been able to watch how they respond to their new environment in real-time,” said Xingchen Ye, IU associate professor of chemistry who developed the experimental technique and is the study’s lead corresponding author.
The U-M team conducted computer simulations that identified the forces responsible for the particles interacting and coming together, laying the groundwork for future research.
