Figure 1. Schematic illustration of FRET-based cell sensing using CP-GFP complexes.

Figure 1

(a) The polymers and GFP form supramolecular complexes through electrostatic interactions, giving rise to FRET responses that are modulated when the complexes interact with cell surface. (b) Chemical structures and characteristics of the cationic CPs used in the study. Mn: number average molecular weight; Mw: weight average molecular weight; PDI: polydispersity index.
