About awarded research
Hydrogel is a soft and fluid material, such as yogurt, and has been applied to medical material such as artificial vitreous body or anti-adhesion material. In order to apply hydrogels to medical materials, it is crucial to predict and control their flowability, but it has been challenging to achieve this under physiological conditions. The research group focused on the stability of the DNA double helix structure enormously depending on the DNA base sequence and developed a new hydrogel cross-linked with the DNA double-helix structure. The macroscopic flow time of the hydrogel was investigated and found to be consistent with the dissociation time of the DNA double helix structure over a wide time range. This result suggests that we will fabricate DNA gels with on-demand fluidity properties.
The technique to control the fluidity of hydrogel accurately is suitable for medical applications such as cell culture media with bio-like fluidity, injectable gel, and soft robotics.

Your impression & future plan
I am very honored to receive this award. I would like to thank all the lab members and Prof. Sakai for their support in receiving the award. I continue to develop new medical materials through research on gel materials.
