If you’re teeny tiny, like microscopic or even nanoscopic in size, existence can be hard. One example of a difficulty a particle of that size might face is how to transport the necessary nutrients ...

Bioengineers have created a new type of petri dish in the form of microscopic, permeable particles that can dramatically speed up research and development (R&D) timelines of biological products, such ...

Tiny particles are opening big doors for medicine, materials science, and even environmental cleanup. Across the world, scientists are racing to understand how these microscopic swimmers behave, ...

Conditions can get rough in the micro- and nanoworld. For example, to ensure that nutrients can still be optimally transported within cells, the minuscule transporters involved need to respond to the ...

Physicists show how microscopic particles can harness fluctuations and external forces to minimize transport energy and even extract usable work. A particle (red sphere) is guided from left to its ...

A new kind of microscope is giving scientists a way to watch life inside cells with a clarity that feels almost unfair.

Stewart Mallory, assistant professor of chemistry and chemical engineering at Penn State, leads a research group that studies active matter, specifically the collective behavior of self-propelled ...

Plastics surround us, whether it's the grocery bags we use at the supermarket or household items such as shampoo and detergent bottles. Plastics don't exist only as large objects, but also as ...
