A UC Santa Cruz researcher has developed a testing method that uses biolayer interferometry to detect biomolecules in serum. Single-use biosensors are automated in “dip and read” formats that are able to provide real-time optical measurements of antigen loading, plasma antibody binding, and antibody isotype detection in under 20 minutes. These tests eliminate long wait times and labor requirements common to other immunoassays while maintaining high sensitivity and specificity.
Abstract
The rapid spread of SARS-CoV-2 and the associated declaration of a global pandemic in 2020 underscore the importance of rapid and accurate infectious disease testing. Serological tests, which facilitate vaccine development and identification of population spread, are commonly used as countermeasures to infection. Existing serological testing methods, like lateral flow immunoassays, are not quantitative and reliably sensitive though. Other immunoassays have better sensitivity and specificity but require long incubation times and are labor-intensive.
