An acceptor fluorophore is a molecule that receives energy from a donor fluorophore in Förster Resonance Energy Transfer (FRET) processes, leading to its excitation and subsequent emission of light at a different wavelength. This mechanism is crucial in bioimaging and molecular sensing applications, enabling the study of molecular interactions and distances at the nanoscale.

Acceptor Fluorophore

acceptor fluorophore

A donor fluorophore is a fluorescent molecule that, upon excitation, transfers energy to an acceptor fluorophore in a process known as Förster Resonance Energy Transfer (FRET). This energy transfer is used to study molecular interactions and distances at the nanoscale, providing insights into biological processes and structures.

donor fluorophore

Förster Resonance Energy Transfer (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 process is widely used to study molecular interactions and dynamics within a range of 1-10 nanometers, making it a powerful tool in biochemistry and molecular biology.

FRET processes

Excitation refers to the process by which an electron or other particle is raised to a higher energy level within an atom or molecule, often through the absorption of energy. This process is fundamental in various scientific fields, including physics, chemistry, and biology, as it underpins phenomena such as fluorescence, phosphorescence, and the operation of lasers.

Molecular interactions are the forces that act between molecules and dictate the structure, dynamics, and function of biological systems. These interactions include various types of forces, such as hydrogen bonds, van der Waals forces, ionic bonds, and hydrophobic interactions, each playing a crucial role in processes like protein folding, enzyme activity, and cellular signaling.
