Enhanced portable detection for Sars-CoV-2 utilizing DNA tetrahedron-tethered aptamers and a pressure meter

Tethering oligonucleotide aptamers to a DNA tetrahedron structure can enhance the recognition of SARS-CoV-2 spike protein to effectively overcome challenges with its detection in current diagnostic assays. Building on this framework, we have developed a unique portable detection method for COVID-19 that provides exceptional sensitivity and selectivity
