Outline of Final Research Achievements

In this study, we addressed the bottleneck challenge in the two-dimensionalization of single-cell information, as proposed by the principal investigator, through collaborative research with research groups in North America and Asia, based on our unique nanofluidic device technology and nano-substance transport theory. We developed the technology for intracellular delivery of nanoparticles for the collection of target biomolecules within a single cell and constructed the corresponding theoretical framework. Additionally, we achieved the single-molecule capture and detection of target biomolecules for the two-dimensionalization of single-cell information. Furthermore, we tackled challenges such as improving the manipulation capabilities of nanoparticles for the two-dimensionalization of cellular information. This study accelerated the development of the proposed technology for the two-dimensionalization of single-cell information.
