The miniature Voyager, which measures 15 micrometers (0.015 millimeters) lengthy, is a part of a project researchers at Leiden College performed to know how form impacts the movement and interactions of microswimmers.

Microswimmers are small particles that may transfer by way of liquid on their very own by interacting with their setting by way of chemical reactions. The platinum coating on the microswimmers reacts to a hydrogen peroxide resolution they’re positioned in, and that propels them by way of the liquid.

“By finding out artificial microswimmers, we wish to perceive organic microswimmers,” Samia Ouhajji, one of many study’s authors, instructed CNN. “This understanding may help in growing new drug supply automobiles; for instance, microrobots that swim autonomously and ship medicine on the desired location within the human physique.”

Through the use of a 3D printer, the scientists have found that they’ll print any form of microswimmers, together with boats and starships. That helps them single out the impact every form has on the movement of swimming particles.

Whereas most individuals would not perceive what the USS Voyager has to do with science, Jonas Hoecht, one of many research’s co-authors, had his personal motive to copy the ship.

“Within the final week of his mission, I promised him we may print any form he favored,” Ouhajji mentioned. “As a serious Star Trek fan, he select the USS Voyager. Moreover, it was additionally to indicate that the kind of shapes we are able to print is nearly limitless.”

Of their mission, the physicists additionally printed shapes like boats, trimers and helices, with every object’s form affecting their swimming behaviors.

Together with understanding how microswimmers can be utilized to scrub wastewater or ship medicine to the physique, the experiment will assist scientists be taught extra about organic swimmers, like sperm and micro organism, and the way they journey by way of the physique.
