The miniature Voyager, 15 micrometers (0.015 millimeters) long, is part of a project researchers at Leiden University conducted to understand how shape affects the movement and interactions of micro-swimmers.

Micro-swimmers are small particles that can move independently through liquid by interacting with their surroundings through chemical reactions. The platinum coating on the micro floats reacts to a hydrogen peroxide solution that they are placed in and that propels them through the liquid.

“By studying synthetic micro-swimmers, we want to understand biological micro-swimmers,” Samia Ouhajji, one of the study’s authors, told CNN. “This understanding could be helpful in developing new drug delivery vehicles, such as microrobots that swim autonomously and deliver drugs to the desired location in the human body.”

Using a 3D printer, the scientists found that they can print any form of micro-swimmer, including boats and spaceships. This helps them find out what effect each shape has on the movement of floating particles.

While most people wouldn’t understand what the USS Voyager has to do with science, Jonas Hoecht, one of the study’s co-authors, had his own reason for recreating the ship.

“In the last week of his project, I promised him that we could print any shape he liked,” Ouhajji said. “As a big Star Trek fan, he chose the USS Voyager. It should also be shown that the types of shapes we can print are almost unlimited. ”

In their project, the physicists also printed shapes such as boats, trimers, and helices, with the shape of each object influencing their swimming behavior.

In addition to understanding how micro-swimmers can be used to purify wastewater or deliver drugs to the body, the experiment will help scientists learn more about biological swimmers, such as sperm and bacteria, and how they move around the body.
