This paper presents a SERS-aptasensor based on colloidal solutions for rapid and specific quantitative determination of the SARS-CoV-2 virus, distinguishing it from other respiratory viruses. Existing SERS-based aptasensors for virus detection often lack quantification or are complex and costly in their design and implementation.
During the COVID-19 pandemic, the development of sensitive and rapid techniques for detection of viruses have become vital. Surface-enhanced Raman scattering (SERS) is an appropriate tool for new techniques due to its high sensitivity. SERS materials modified with short-structured oligonucleotides (DNA aptamers) provide specificity for SERS biosensors. Existing SERS-based aptasensors for rapid virus detection are either inapplicable for quantitative determination or have sophisticated and expensive construction and implementation. In this paper, we provide a SERS-aptasensor based on colloidal solutions which combines rapidity and specificity in quantitative determination of SARS-CoV-2 virus, discriminating it from the other respiratory viruses.
