In brief: Like living cells, oil-in-water droplets reach out with 'arms'
By Sam Sholtis
Oil-in-water droplets respond to chemical cues by forming arm-like extensions that resemble filopodia, which are used by living cells to sense and explore their environment. A research team led by chemists at Penn State studies the droplets to glimpse how matter may have transitioned to life billions of years ago. The researchers dissected the mechanism through which these arms form and showed that they respond directionally, growing toward or away from specific chemicals.
