A dozen robots, each smaller than a grain of sand, sit on your fingertip. These are smartlets, tiny marvels from Chemnitz University of Technology that pack a lot of tech into their millimeter sized bodies. Developed by a team led by Prof. Oliver G. Schmidt, these water robots move, sense and talk to each other in water, and could one day monitor lakes or swim through our bodies for medical diagnostics.

In the relentless pursuit of precision medicine, a groundbreaking development in microrobotics promises to revolutionize targeted drug delivery. Researchers at the University of Michigan and the University of Oxford have unveiled a novel class of microrobots—termed permanent magnetic droplet-derived microrobots (PMDMs)—that can be precisely steered within complex biological environments to administer therapeutics exactly where needed. This innovation addresses a key limitation of conventional intravenous drug delivery, which notoriously directs less than one percent of administered drugs to the intended tissue, often causing systemic side effects and reduced efficacy.

Researchers at the University of North Carolina have created microscopic soft robots shaped like flowers that can change shape and behavior in response to their surroundings, just like living organisms do. These tiny "DNA flowers" are made from special crystals formed by combining DNA and inorganic materials. They can reversibly fold and unfold in seconds, making them among the most dynamic materials ever developed on such a small scale.
