    Abstract: The present disclosure relates to a fine particle-trapping sensor including: a plasmonic hotspot layer formed of a first metal; and a trapping layer formed of a second material. The inventors of the present disclosure have made extensive research efforts to develop a more effective and novel sensor for the real-time and high-sensitivity detection of droplets emitted from the oral cavity. As a result, the inventors have developed an alloy composite nanostructure including a Raman sensor layer, formed of a metal, and a trapping layer formed of a dielectric material, and have found that, when the ratio between the two layers is adjusted, the alloy composite nanostructure effectively traps respiratory droplets rapidly emitted from the oral cavity and detects coronavirus (SARS-CoV-2 lysate) in the respiratory droplets at a concentration of 10 pfu/ml, indicating that the composite nanostructure may be very advantageously used in the field of fine particle trapping.

    Abstract: A microlens array-based ultrathin microscope is provided. The microlens array-based ultrathin microscope includes a filter unit configured to selectively transmit fluorescence manifested in a measurement sample, and an image unit configured to acquire an image from light transmitted by the filter unit. The filter unit is formed to be in contact with or spaced apart from one surface of a transparent substrate, and the image unit includes a microlens array formed on an opposite surface to the transparent substrate in which the filter unit is formed, and an image sensor configured to collect image information of the microlens array.

    Abstract: The present invention provides a lens having broadband anti-reflective nanostructures formed using nano-island masks and a method for making the same, in which nanostructures having a size and period equal to or smaller than the light wavelength are formed on the surface of a lens to obtain a lens having decreased reflectance, increased transmittance and high efficiency. The lens having broadband anti-reflective nanostructures formed using nano-island masks comprises: a lens having a planar shape or a predetermined curvature; and anti-reflective nanostructures formed on one surface of the lens using nano-island masks, in which the horizontal and vertical cross-sections of the anti-reflective nanostructures have a size equal to or smaller than the light wavelength.
