Welcome to the "NanoBiomaterials Laboratory" homepage. Our group focuses on "synthesizing inorganic nanomaterials for biomedical applications".  Specifically, we are developing  (1) Inorganic Nanomaterials for Implantable electronics, (2) Catalytic Nanozyme for the treatment of reactive oxygen species- related disease, and (3) Minimally invasive devices.  Our research field is a multidisciplinary, convergent field that closely connects various disciplines such as chemistry, engineering, medicine, and biology. We welcome highly motivated students from diverse backgrounds.

 "Nanobiomaterials Laboratory" 홈페이지에 오신 것을 환영합니다. 우리는 무기나노재료를 활용하여 바이오메디컬 분야에 응용하는 연구를 하고있습니다. 구체적으로 (1) 무기나노재료를 활용한 생체삽입용 유연성 생체전극 제작, (2) 나노자임을 활용한 활성산소 관련 질병 치료, 그리고 (3) 최소침습적 의료기기 제작에 관한 연구를 하고 있습니다. 저희 연구분야는 화학, 의학, 생물, 공학 등 다양한 학문분야가 서로 밀접하게 연결되어 있기 때문에 다양한 전문분야의 배경을 가진 연구자들이 합류할 수 있습니다.
