TA

TA is an anthracene derivative with ultrasound-activated luminescence properties. TA can be activated by ultrasound and emit fluorescence. TA is generally not used directly but can be used to construct TA-NP nanoparticles. The ultrasound-activated luminescence of TA-NPs is mainly concentrated in the wavelength range of 600~650 nm, exhibiting good penetration ability into biological tissues, making it suitable for in vivo imaging[1].
