FRET is a distance-dependent interaction between two light-sensitive molecules, where energy transfer occurs from a donor to an acceptor molecule without the emission of a photon. This technique is widely used in molecular biology to study interactions and distances within biomolecules at the nanometer scale.

Energy transfer is the process by which energy moves from one system or object to another, often changing form in the process. This fundamental concept is crucial for understanding various physical phenomena, from biological processes to mechanical systems and thermodynamics.

Molecular biology is a branch of science that explores the structure and function of the molecules essential to life, focusing on the interactions between various systems of a cell, including the interrelationship of DNA, RNA, and protein synthesis. It provides insights into the molecular mechanisms of genetic replication, transcription, translation, and cell function, forming the foundation for understanding complex biological processes and disease mechanisms.

Biological interactions refer to the various ways in which organisms in an ecosystem interact with one another and their environment, influencing survival, reproduction, and ecosystem dynamics. These interactions can be positive, negative, or neutral and include processes such as predation, competition, mutualism, and commensalism, which are fundamental to ecological balance and biodiversity.

The nanometer scale refers to dimensions typically between 1 and 100 nanometers, where unique quantum mechanical effects and surface phenomena become significant, altering the properties of materials compared to their bulk counterparts. This scale is crucial in nanotechnology and nanoscience, enabling the development of innovative applications in electronics, medicine, and materials science.
