Invention:
This invention introduces a novel metamaterial emitter system designed to enhance super-resolution imaging by leveraging the interaction between plasmonic nanoparticles and temperature-sensitive emitters, such as quantum dots. The plasmonic nanoparticle core is designed to efficiently produce localized heat upon excitation, which then interacts with an array of surrounding photosensitive emitters. The emitter uses two distinct excitation beams to allow for independent control of the excitations of the emitters and the heating of the core. By selectively filtering out the redshifted light, the system enables precise control and filtering of emitted wavelengths, which is essential for high-resolution optical imaging and sensing.
Background:
This technology offers a new approach to super-resolution imaging, which has increasing importance in fields such as microscopy, optical sensing, and imaging. Super-resolution imaging breaks the diffraction limit to resolve structures at the nanometer scale. Conventional techniques, such as STED (Stimulated Emission Depletion) microscopy, rely on intricate optical setups and molecular photophysics, which often lead to lower efficiency and resolutions. By using temperature-sensitive emitters such as quantum dots instead of the fluorescent molecules used in STED, this technology provides improved resolution, efficiency, and adaptability for advanced imaging applications.
