| Outline of Final Research Achievements |
In recent years, antibodies have been widely used for medical purposes, but there is a problem that antibodies tend to degrade during purification, transportation and storage processes. Therefore, when designing therapeutic antibodies, it is necessary to strictly determine the methods and conditions of antibody processing and storage in each process based on a combination of separation and spectroscopic analyses. In this project, a novel sensing method was developed to address these issues. By using cross-reactive complexes between fluorescent DNAs and nanosized-graphene oxides (nGOs), the information on antibody misfolding was transduced into response fingerprints, and multivariate analyses of these fingerprints allowed for rapid and facile identification of the degraded states of the antibodies.
