The front cover illustrates a core−shell upconversion nanoparticle travelling in the blood stream. Under excitation of near‐infrared light, the nanoparticle shows tunable emissions in the visible and ultraviolet region of the spectrum, allowing for a variety of biomedical applications such as sensitive biodetection and deep‐tissue imaging. The advances of upconversion research in the past few years are largely attributed to the establishment of nanostructural engineering as a general strategy for unprecedented optical tuning. Herein, recent progress in controlling upconversion in nanostructured materials and utilizing upconversion processes for emerging biomedical applications are discussed.
