Near-Infrared Light Triggered the Shape Memory Behavior of Polydopamine-Nanoparticle-Filled Epoxy Acrylate

چکیده
Through the effective combination of photothermal conversion agent polydopamine (PDA) nanoparticles and epoxy acrylate polymer (EA), a new kind near-infrared (NIR) light-triggered shape memory (PDA/EA) is developed. Due to outstanding effect PDA, even with very low concentration PDA (0.1 wt.%), when exposed an 808 nm NIR light power 1 W/cm2, temporary shapes can be fully light-responsive, recovered in 60 s. Based on dynamic thermomechanical analysis thermal gravimetric analysis, it seen that introduction beneficial for improving mechanical properties resistance compared EA. As environmentally friendly highly efficient photoactive SMP, PDA/EA has great application prospect.

Near-infrared light photoacoustic ophthalmoscopy
We achieved photoacoustic ophthalmoscopy (PAOM) imaging of the retina with near-infrared (NIR) light illumination. A PAOM imaging system with dual-wavelength illumination at 1064 nm and 532 nm was built. We compared in vivo imaging results of both albino and pigmented rat eyes at the two wavelengths. The results show that the bulk optical absorption of the retinal pigment epithelium (RPE) is on...
