Plasmon-induced near-infrared fluorescence enhancement of single-walled carbon nanotubes

Ardemis Anoush Boghossian, Giulia Tagliabue, Alessandra Antonucci, Shang-Jung Wu, Theodoros Tsoulos, Sayyed Hashem Sajjadi, Amirmostafa Amirjani

Single-walled carbon nanotubes (SWCNTs) emit near-infrared (NIR) fluorescence that is ideal for optical sensing. However, the low quantum yields diminish the sensor’s signal-to-noise ratio and limits the penetration depths for in vivo measurements. In this ...
