Abstract
Near-infrared(NIR) light has great potential in biomedical application due to its advantages such as deep penetration depth and low photodamage to biological tissues.If we want to use NIR light that has entered animal body,for in-vivo diagnosis and therapeutic intervention,a prerequisite is to obtain nanomaterials and/or nanodevices that can absorb or convert NIR light.This paper reviews the recent research progress in NIR-lightdriven nanomaterials and/or nanodevices,including up-converting rare-earth nanophosphors,980-nm laser-driven generator,and photothermal nanoagents.The main attention has been given to the biological application of these nanomaterials and/or nanodevices.At last,the present problems and the future development trends are pointed out.
