Abstract

We demonstrate a nanoparticle based ratiometric fluorosensor suitable for non-invasive high-resolution imaging of complex samples. Coextraction generates a movement of a solvatochromic dye, with a consequent shift from plasmophore coupled emission towards longer wavelength scattering enhanced emission. The nanoparticle doped sensors confirmed superior sensitivity, reversibility, durability and overall image quality.
