Oil Droplets Change Shape Like Living Cells

Topic: Physics

Researchers at New York University created oil droplets that can change shape and swallow their surroundings like living cells. They used a soap-like molecule to make this happen. This discovery could lead to new materials that can adapt to their environment.

Scientists at New York University have made an amazing discovery. They took tiny oil droplets in water and added a special soap-like molecule called P123 block copolymer. When they did this, the oil droplets started changing shape in complex ways. They formed different shapes like flowers, branches, dumbbells, discs, and cups.

The researchers were surprised to find that these changes happened without any living cells or biological parts involved. They could control the shape of the droplets by adjusting the concentration of the soap molecule or changing the temperature. This means they can make the droplets change shape again and again.

But that's not all - the oil droplets can also swallow their surroundings like living cells do. When a droplet folds in on itself, it wraps around the surrounding fluid and traps whatever is floating nearby inside. This behavior is similar to a process called macropinocytosis, where a cell gulps down some of its surroundings.

The researchers are excited about this discovery because it could lead to new materials that can adapt to their environment or capture cargo on demand. They think these tiny containers could protect precious things and have many potential applications.
