Deepti Singh is a bioengneer who has been exploring the application of polymeric materials in restoring or repairing injured tissues and organs. With a Ph.D in genetics and biotechnology, she has worked extenisively for the last decade to develop functional biomimetic that can enhance differeniation of embyronic stem cells into desired linage. This book focuses on interesting and new aspects of biomaterial design and its applications. With the emergence of bio-ink, 3D printing could potentially change the entire apporach of regenerative medicine in which instead of restoring and repairing, the disease tissue can be replaced.
