A upconversion luminescence derived photoelectrochemical Immunoassay for ultrasensitive detection to Alpha-fetoprotein under near infrared lights illumination.
A near-infrared (NIR) activated theranostic nanoplatform based on upconversion nanoparticles (UCNPs) is developed in order to overcome the hypoxia-associated resistance in photodynamic therapy by photo-release of NO upon NIR illumination.
In this study, a near-infrared (NIR) theranostic photosensitizer was developed based on a heptamethine aminocyanine dye with a long-lived triplet state.
