Patent number: 11921048Abstract: 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.Type: GrantFiled: October 28, 2022Date of Patent: March 5, 2024Assignee: Korea Advanced Institute of Science and TechnologyInventors: Ki-Hun Jeong, Charles Soon Hong Hwang
