Near-field scanning optical microscopy (NSOM) is a powerful and unique approach to characterize the chemical, physical and potentially biochemical properties of materials with the nanometer scale resolution in real-time. A key element for NSOM systems that combine optical spectroscopy with scanning probe microscopy, is the actual probe itself. While many commercial vendors offer off-the-shelf metal-coated tips, only one in ten tips offers enough field enhancement to start performing spectroscopic measurements. There is a critical need for the development of reliable, efficient, and broadband near-field probes. “Campanile” near-field probe has been proven to show superior spatial resolution and optical throughput and eliminate unwanted background signals. HighRI Optics, Inc. in collaboration with Molecular Foundry at Lawrence Berkeley National Laboratory (LBNL), proposes to develop manufacturing technology to commercialize campanile probes based on nanoimprint lithography. The final product will be offered in two platforms; an optical fiber and AFM cantilever to maximize compatibility with the most commercial AFMs. The fundamental spatial resolution for optical based techniques is limited to a few hundred nanometers due to the diffraction limit and is not capable to probe and distinguish spatially varying properties of matter at the nanometer scale. This revolutionary imaging tool will circumvent this limitation and will be used in a broad range of applications including solar cells, new hard drives, and artificial proteins.
