T1 - Effects of doxorubicin-loaded UCNP@MSN core-shell particles with a thermoresponsive nanovalve in melanoma cells N2 - Melanoma, one of the most aggressive forms of skin cancer, has an increasingly higher incidence. When detected in advanced stages, tumour eradication is often incomplete, contributing to poor prognosis with conventional treatments. Upconversion nanoparticles (UCNPs) haveunique optical properties that allow their effective use in several biomedical applications. This includes the excitability under near-infrared (NIR) excitation light, which has a relatively high penetration depth in tissue, a multitude of characteristic emission bands in the ultraviolet (UV), visible (Vis), NIR, and short-wave infrared (SWIR), along with long luminescence lifetimes, and high photostability. Mesoporous silica nanoparticles (MSN) with nanovalves or derived coatings have widely been used for triggered and targeted drug delivery in the past. Anticancer drugs can be loaded into the pores of MSN, enabling spatiotemporally controlled drug release.
