Example Sentences

Professor Ku showed confidence about the potential applications of this research, stating, "This study opens doors to the creation of self-assembling optical particles, streamlining the complex process conditions typically associated with colloidal crystal structure and pattern formation."

From Science Daily

Such colloidal particles -- small solid particles suspended in a fluid phase -- can be seen as an excellent way to measure and also manipulate the motion of the living cells' membrane.

From Science Daily

The researchers' device represents the first hydrovoltaic application of a technique called nanosphere colloidal lithography, which allowed them to create a hexagonal network of precisely spaced silicon nanopillars.

From Science Daily

They explain, "In previous work since 2020, we were the first to achieve precise particle size control and develop colloidal suspensions of spherical and crystalline silicon nanoparticles. These single silicon nanoparticles scatter light in bright colors by the phenomenon of 'Mie resonance,' which allows us to develop structural color inks."

From Science Daily

"We show that these can be used for calculations and at the same time present a method that suppresses the influence of disruptive effects, such as noise, in the movement of the colloidal particles."
