Tissue-interfacing / Medical glue

Optically anisotropic topical hemostatic agents containing plant polyphenols (Adv. Funct. Mater. 2021)
For prevention of internal rehemorrhage in limited clinical settings, it is important to develop effective topical hemostatic formulations and monitor their hemostatic process without optical labeling. Thus, we developed optically anisotropic liquid crystal/plant polyphenol-based hemostatic coacervate for clear identification of blood coagulation process. Spontaneous generation of “polyphenol-blood physical barrier” on the tissue followed by green colored visualization of liquid crystal apparently showed termination of blood coagulation.

Hemostatic agents/medical devices (Nat. Mater. 2017, Adv. Funct. Mater. 2015)
Tissue-adhesive biomaterials have been attracted for hemostatic agents, wound closure, and other applications to multifunctional medical devices. In particular, we have developed hemostatic polymeric biomaterials for surface coating of medical tools/devices and controlling external/internal bleeding on surgical procedures. Our research scope is highly effective to solve challenging issues of delayed hemostasis from patients with chronic diseases, such as diabetes, advanced cancer, or hemophilia, patients taking aspirin and undergoing chemotherapy/cerebral surgery, and rare case patients with Ebola virus infection.
