Fluorogenic probe quantum-yield enhancement framework: E = Φ_bound / Φ_free (dark-to-bright turn-on)

Layer 2 — Chemistryin the chemical-biology subtree

Fluorogenic-probe quantum-yield enhancement: conditional fluorophores designed to be quenched in the free state and become emissive on binding a protein tag (HaloTag, SNAP-tag, self-labelling enzymes) or on reacting with a biological…
