Recent advances for liquid metals:Synthesis,modification and bio-applications

摘要

Considering the application requirements for modern biomedicine,research into novel biomaterials with unusual functions is highly desired.As an alternative,liquid metals(LMs),a nontraditional family of metal materials,have piqued the interest of biomedical researchers and made significant advances in biomed-ical areas,owing to their shape transformability,self-healing capability,excellent electrical,and thermal conductivities.In particular,many functionalized strategies for the preparation and modification of LMs or LMs-based composites to achieve extended biomedical applications have been investigated in recent years.These findings provided inspiring while constructive reference for the fabrication and engineering of novel LMs-based composites.Herein,in this topic review,we elaborate on the recent advances of LMs-based functional materials,with particular focuses on the synthesis,modification,and bio-applications,especially in antitumor therapy,antibacterial,contrast agent for imaging,bone repair,electronic skin sen-sor,and nerve connection agent.Further on,the current challenges and future prospects of LMs-based composites are carefully discussed.
