Attobiology

Definition

Attobiology is the study of processes occurring on the attosecond timescale, which is one quintillionth of a second (10^-18 seconds). This field explores the dynamics of electron movements in atoms and molecules, allowing scientists to observe and manipulate these rapid events in real time. Attobiology relies heavily on ultrafast lasers to generate attosecond pulses, enabling researchers to probe fundamental interactions in chemistry and physics.
