Lab-on-a-chip: Summary of 3D/4D Printed Biochips

Abstract

Looking to the future, 3D/4D printed biochips hold immense potential for transformative advancements in healthcare and biomedical research. Advances in bioink formulation, integration with emerging technologies, and bioprinting of complex tissues and organs will further expand the capabilities and applications of biochips. Accordingly, this chapter provides a comprehensive exploration of 3D/4D printed biochips, their design, fabrication, advantages and challenges and highlights the significant impact of 3D/4D printing in the field of biochips, enabling the creation of complex structures, customization, and integration of functional components. The advantages of 3D/4D printed biochips include improved performance, enhanced customization, and the potential for novel applications such as organ-on-a-chip models and point-of-care diagnostics. However, challenges remain, including material selection, printing resolution, and integration of functional components, which require ongoing research and optimization efforts.
