Wave-particle duality

Definition

Wave-particle duality is a fundamental concept in quantum mechanics that describes how particles, such as electrons and photons, exhibit both wave-like and particle-like properties. This duality is essential for understanding phenomena at the nanoscale, particularly how particles behave in nanofluidic environments where their quantum characteristics can significantly influence transport mechanisms and interactions with other particles.
