 Piezoelectric microfluidics has been used to create jellyfish-shaped micro-particles which can be used for adsorbing organic pollutants. This technique allows for precise control over particle size and shape, as well as the ability to create multiple compartments within the same particle. These particles also possess the ability to move in response to external stimuli, making them ideal candidates for use in environmental remediation.
