Improving penetration depth in biological imaging using Nd3+/Yb3+/Er3+-doped upconverting nanoparticles
We have synthesized and evaluated in tissue phantom measurements a new type of Nd-codoped upconverting nanoparticles. They provide improved signal strengths from deep regions in a tissue phantom as compared to conventional upconverting nanoparticles, a result also suggesting they will provide less issues with heating the tissue during measurements.
