Recent Advances in Upconversion Nanoparticle-based Nanocomposites for Gas Therapy

Gas therapy has attracted wide attention for the treatment of various diseases. However, a controlled gas release is highly important for biomedical applications. Upconversion nanoparticles (UCNPs) can precisely convert the...

Photocontrolled chondrogenic differentiation and long-term tracking of mesenchymal stem cells in vivo by upconversion nanoparticles

Mesenchymal stem cells (MSCs) have multiple differentiation potentials and its clinical application is limited with control cell differentiation and long-term tracing in vivo. Here, we developed a upconversion nanoparticle (UCNP)...

Conjugate and non-conjugate controls of sensitizer to enhance dye-sensitized upconversion luminescence

Although dye sensitization is an efficient strategy to improve upconversion luminescence of lanthanide-doped upconversion nanoparticles (UCNPs), the sensitization effect is limited due to the high probability of dyes aggregation. To...
