文摘
- •
Silica coating was demonstrated to be much more effective in enhancing the PA signal amplitude comparing to soft polymer.
- •
PA enhancement was attributed to the increased phonon modes and phonon energy with the introduction of the SiO2 coating.
- •
Multilayer structure was an effective design for dual-modal fluorescence and PA imaging probes with improved PA property.
