effects of polarity and functionality on optical properties of fluorescent polymer nanocarriers

During the past decades, light-responsive polymer nanocarriers have received considerable attention due to their significant applications. there has been a lot of interest in development of chemosensors based on fluorescent polymers to sense a wide range of analytes, such as ph, polarity, temperature, etc. in this study, reverse atom transfer radical polymerization (ratrp) was used to synthesize acrylic polymers with well-controlled molecular weight and also narrow distribution. to study the effect of polarity and ph, fluorescein was doped to polymers during nanoprecipitation to reach light-responsive polymer nanoparticles. the results obtaind from uv-vis and fluorescence analyses showed that the polarity and ph of media affect the optical properties of these nanocarriers.
