AggFluor is derived from the synthetic GFP chromophore, 4 hydroxybenzylidene imidazolinone (HBI), and belongs to the class of molecular rotor fluorophores widely used in biological imaging due to their sensitivity to environmental factors such as viscosity. When bound to properly folded proteins, AggFluors are quenched and remain non fluorescent; however, protein misfolding or
