[Project Description]
MEXT project “Genome Modality" Group: DNA Nanoscale Modality
Research Summary: DNA is a hierarchical soft matter that has a rigid structure at the nanoscale but has flexible macromolecular properties at the genomic DNA scale, where the genomic DNA scale is mesoscopic (hundreds of nm) to microscale (tens of micrometers)). While the nanoscale thermodynamics of DNA, governed by base sequences, is known, less is known about the mesoscopic scale and microscale structural properties and dynamics, essential for cell biology.
This project will elucidate the biophysics and soft matter physics principles that explain how DNA exhibits mesoscopic scale to microscale multimodal structures, properties, and functions of genomic DNA in a tiny space of the cell nucleus scale, based on nanoscale information. Here, we estimate the phenomena and properties such as liquid-liquid phase separation, intramolecular phase separation, interfacial tension, viscoelasticity, volume phase transition, and non-equilibrium, as the mesoscopic scale to microscale multimodal structures, properties, and functions. To construct genome DNA models (artificial chromatins), we use DNA gels and DNA droplets constructed with the self-assembly of DNA nano-motifs and DNA origami nanostructures. Also, to construct cell nuclear models (artificial cell nuclei), lipid membrane vesicles generated by microfluidics are used. We will apply findings in this study to biophysical and applied physics technologies, such as artificial cell engineering and molecular robotics.

This position is open to highly motivated postdoctoral researchers in DNA nanotechnology, nucleic acid chemistry, life sciences, biophysics, soft matter physics, biomolecular chemistry, MEMS, etc., who can engage in experimental research of the above research plan.

[Job Description]
Construction of various shapes mesoscopic-sized DNA gel/DNA droplets (genome DNA models) by assembling DNA nanostructures. Measuring physical properties such as viscoelasticity and stability. Elucidation of the physicochemical mechanism of the genome DNA models using the knowledge of biophysics, soft matter physics, and polymer science. Functionalization of the genome DNA models using enzymes and other chemical reactions. Control of the physical properties of the genome DNA models using light and other methods. Besides, building a cell nuclear model to understand the interaction with the lipid membrane.
