Solid lipid nanoparticles labelled with a photoacoustic BODIPY dye exhibit complex but continuous transformation for both optical and photoacoustic spectra as the BODIPY content increases. Gaussian decomposition of the spectra reveals the interplay between three optical absorption bands and unveils a band-dependent and concentration-dependant photoacoustic generation efficiency above 1.
