Product Details
Name：Ag2S QDs
Product overview
Quantum dots with near-infrared fluorescence (NIR) are a new type of quantum dots, which have unique properties due to their deeper tissue penetration compared to visible light. Near infrared light also effectively overcomes the spontaneous fluorescence of organisms, making near-infrared quantum dots particularly attractive in biological imaging applications for disease diagnosis. Semiconductor metal sulfide material silver sulfide quantum dots (Ag2S QDs), as quantum dots in the near-infrared region, have been widely used in optical imaging, photoacoustic imaging, sensing, and photothermal therapy, especially in the NIR - ¡ãCregion as effective biological imaging nanoprobes to guide disease diagnosis and treatment. Due to their excellent near-infrared fluorescence performance and biocompatibility, Ag2S quantum dots have become a rising star in the field of near-infrared quantum dots. Compared with traditional NIR quantum dots, Ag2S quantum dots have better application prospects in biomedical fields due to their absence of toxic components.
