The near‐infrared (NIR) region of the spectrum is called the “therapeutic window” because NIR light can penetrate deeply into tissue. Therefore, NIR‐sensitive materials are attractive for biomedical applications. Recently, upconverting nanoparticles (UCNPs) were used to construct NIR‐sensitive materials. UCNPs convert NIR light to UV or visible light, which can trigger photoreactions of photosensitive materials. Here, how to use UCNPs to construct NIR‐sensitive materials is introduced, applications of NIR‐sensitive materials with a focus on biomedical applications are highlighted, and the associated challenges are discussed.
