Abstract: The present invention relates to the field of assay devices and methods for performing assays, such as immunoassays. The system comprises a means to receive the target sample collected from a subject; a means to measure the target analyte possibly present in said target sample; and a process of measuring the target analytes in real time manner. The target analyte includes but is not limited to any biological analyte, microbial entity like those of viral or bacterial sources such as SARS-CoV-2. The invention thus primarily relates to measuring analytes of interest to detect and treat related indications, such as COVID-19.

Abstract: A fatty acid based composition for treatment and/or prevention of enveloped-virus related infections by administering fatty acid based compositions. The present invention further provides a free fatty acid based sprayable composition to prevent and/or treatment of SARS-Virus related infections. The fatty acids used in the present invention are Linoleic acid (LA), ?-linolenic acid (ALA) and gamma-linolenic acid (GLA). In a preferred embodiment, we propose that topical administration of naturally occurring fatty acids in an optimal formulation may be beneficial in the prophylaxis of respiratory enveloped viruses and in particular the lipid-rich SARS-CoV-2 virus. This could be administered via nasal and/or oral route. The composition comprises at least one fatty acid, a suitable carrier, preservative, cosolvents and surfactants and/or cyclodextrin used as an excipient that may also enhance anti-viral properties.
