Single molecule research involves studying individual molecules and their interactions in order to gain insight into fundamental biological processes, chemical reactions, and physical properties at the molecular level. This field utilizes advanced imaging techniques, such as single molecule fluorescence microscopy and atomic force microscopy, to observe and manipulate individual molecules in real-time. By examining molecules on a single molecule level, researchers can uncover unique properties and behaviors that are not observed in bulk samples, leading to a deeper understanding of complex molecular systems. Single molecule research has applications in various fields, including biology, chemistry, physics, and materials science.
