Special Issue Information

Liquid metals, particularly gallium-based alloys, have emerged as a promising class of functional materials for next-generation biomedical engineering. Their unique properties, including high electrical and thermal conductivity, fluidity, mechanical flexibility, and tunable surface chemistry, offer exciting opportunities for developing innovative biomedical materials, devices, and technologies.

Recent advances in liquid metal nanotechnology, surface engineering, advanced manufacturing, and functional composites have significantly expanded their potential applications in flexible bioelectronics, wearable and implantable devices, biosensing, soft robotics, drug delivery, and therapeutic technologies. Nevertheless, challenges remain in controlling material properties, improving biological compatibility, achieving scalable fabrication, and translating these technologies into practical biomedical applications.

This Special Issue aims to highlight recent advances in the design, synthesis, fabrication, functionalisation, and biomedical applications of liquid metal-based materials and technologies. We welcome original research articles, comprehensive reviews, and perspectives that address fundamental scientific challenges, emerging technological developments, and innovative biomedical applications.
