Particle behavior is a research area that focuses on studying the movement, interactions, and properties of individual particles at the micro or nanoscale. This field incorporates a range of disciplines, including physics, chemistry, biology, and engineering, and is essential for understanding various natural and synthetic systems. By investigating how particles behave in different environments, researchers can gain insights into complex phenomena such as the behavior of colloids, the dynamics of biological molecules, and the behavior of nanoparticles in drug delivery systems. Particle behavior research often involves experimental techniques such as microscopy, spectroscopy, and particle tracking, as well as computational modeling and simulations.
