[Preface for special issue on bioengineering and human health (2019)]

Human health is the foundation of human survival and development. It is an important objective of sustainable development to enhance human health level. With the development of science and technology, bioengineering, as an interdisciplinary biological technology, is becoming the key driver of these goals. This special issue reviewed and discussed the recent progress and future perspectives of bioengineering technologies in the biomedical applications from the aspects of engineering design, disease diagnosis, gene- and cell-based therapies. We hope this special issue could provide valuable references for promoting bioengineering technologies used for the healthcare applications.
