Janus membranes

Janus membranes are specially engineered materials that have two distinct sides with different properties—like a "passenger side" and a "driver side." For example, one side might repel water (hydrophobic), while the other attracts it (hydrophilic). This duality allows Janus membranes to selectively control what passes through, making them useful in applications like filtration, sensors, or protective barriers. Their unique structure enables precise separation and interaction with various substances, which can improve efficiency and functionality in technological and medical devices.
