도 9는 경화가 가해지지 않은 알긴산 용액의 점도를 측정한 것이다. 그 값이 10 cP 이하로 측정되었으며, 잉크젯 프린팅 방식에 적합함을 확인할 수 있다.
도 10은 잉크젯 프린팅을 위한 형태 디자인(위)과 실제 출력 결과(아래)를 나타낸 것이다.
도 11은 HS68 Cell 및 NIH3T3 Cell-Laden 바이오잉크의 세포 독성 테스트 결과이다.
도 12는 5% 알긴산 하이드로겔 및 알긴산-티라민 하이드로겔의 경화 방법에 따른 저장 모듈러스를 나타낸 것이다.
도 13의 (a)는 광경화한 알긴산-티라민 하이드로겔의 시간에 따른 중량 변화를 표로 나타낸 것이며, (b)는 광경화한 알긴산-티라민 하이드로겔의 시간에 따른 초기 중량 대비 동결 건조 중량비의 변화를 표로 나타낸 것이다.
도 14는 알긴산-티라민 하이드로겔을 주사전자현미경으로 관찰한 이미지이다.
도 15는 CaCl2 농도에 따른 구조체의 Live/Dead 분석을 진행한 결과이다.
