What Does TPA Stand For?

TPA stands for Two Photon Absorption

TPA, or Two Photon Absorption, is a nonlinear optical process in which two photons are absorbed simultaneously by a molecule, leading to an excited state that facilitates various applications in fields such as microscopy, spectroscopy, and photodynamic therapy. This process allows for increased resolution and depth penetration in imaging techniques, enabling researchers to study biological systems with higher sensitivity and specificity.
