Abstract: 
liquid metals are a category of emerging materials possessing massive potentials in biomedical engineering, including biosensing, drug delivery, patterning and wearable electronic devices. Besides their high electrical conductivity and flexibility, the high surface activity and shape fidelity allows liquid metals to achieve improved printability. However, as liquid metals are prone to oxidation, preliminary surface treatment was critical in various applications with desirable performances. The modification methods generally include sonication in ligands solution, galvanic replacement reaction and electroplating, aiming to reduce the oxidation of liquid metals while introducing functional groups for the subsequential bio-designs and manufacturing. Herein, recent development in strategies for liquid metal surface modification and patterning, is reviewed and discussed. Various patterning techniques and biomedical applications utilizing liquid metal inks are summarized, and perspectives of liquid metal additive manufacturing in future applications are proposed.
