This book highlights the latest clinical research and advancements in 3D (bio)printing and 4D
printing using stimulus-responsive hydrogels as well as the concept of self-healing and its
amalgamation with 3D printed injectable cell-laden tissue constructs. It also explores the use
of metal-free click chemistry and enzymes such as horseradish peroxidase hematin tyrosinase
and transglutaminase to obtain chemically crosslinked hydrogels and the in vitro and in vivo
responses. Lastly the book briefly examines the future of drug delivery and the potentials
offered by microrobotics and self-powered devices based on triboelectric nanogenerators. This
book caters to biomedical researchers and clinical practitioners working in tissue
reconstruction and drug therapeutic delivery.
