Sacrificial Biofabrication for Vascularization: Concept, Materials, Technologies, and Applications. [PDF]

Adv Mater
Vasculature is indispensable for tissue viability in regenerative medicine. The sacrificial biofabrication enables precise fabrication of vascular channels by using temporary templates that are subsequently removed. This review defines the concept and delves into sacrificial materials, surrounding materials, fabrication technologies, and biomedical ...

An overview of functional biolubricants

Friction, 2022
AbstractAt present, more and more diseases are associated with the lubrication dysfunction, which requires a systematic study of the complex lubrication behavior of tissues and organs in human body. Natural biomacromolecular lubricants are essential for maintaining ultra-low coefficients of friction between sliding biological interfaces.
