Light-responsive carriers have been used for the controlled release of antitumor drugs in recent years.However, most light-responsive vectors require high-energy ultraviolet or visible light to achieve local drug release, and ultraviolet light would cause cellular damage. Near-infrared light has a ...
near-infrared (NIR) light is preferable due to its deep tissue penetration and low phototoxicity. However, most of the photocleavable groups cannot be directly activated by NIR light. Here, we report a upconversion-like process via only one step of energy transfer for ...
Owning to its excellent tissue penetration capacity, near-infrared (NIR)-light has attracted intensive research interests in nanomedicine for either direct photothermal killing of cancers or precisely controlled drug release in recent years. Unlike conventional nanoscale drug delivery systems (NDDSs), NIR...
中文名称:近红外光(near infrared,NIR)和偶氮苯基团修饰介孔二氧化硅纳米颗粒(MSN) 说明:介孔二氧化硅纳米颗粒具有高度可调的孔道结构和大表面积,这使它们能够高效负载药物或其他功能分子。偶氮苯是一种光响应分子,其分子结构可以在紫外光或可见光照射下发生顺反异构转变(从顺式到反式或者反过来),这一特性可以用于控制...
Schematic illustration of LSPR-induced stepwise hole transfer process. Decay processes of hot holes generated in CuS NCs and CdS/CuS HNCs are shown. The red arrows means plasmon excitation by near-infrared (NIR) light. For CuS NCs, the generated hot holes decayed via hole–hole and phonon–ho...

High-power broadband near-infrared (NIR) light sources based on laser-excited phosphors are highly desirable for photonics applications in night vision, biomedical imaging and sensing; however, the inherent energy gap law poses a great challenge for the development of efficient NIR luminescent materials...

We describe fuel-free, near-infrared (NIR)-driven Janus mesoporous silica nanoparticle motors (JMSNMs) with diameters of 50, 80, and 120 nm. The Janus structure of the JMSNMs is generated by vacuum sputtering of a 10 nm Au layer on one side of the MSNMs. Upon exposure to an NIR lase...
Near-infrared (NIR, 740–780 nm) optogenetic systems are well-suited to spectral multiplexing with blue-light-controlled tools. Here, we present two protocols, one for regulation of gene transcription and another for control of protein localization, that use a NIR-responsive bacterial phytochrome B...
