Needle‐free, Liquid Metal‐embedded Electrospray Deposition System for Controlled Microdroplet Printing (Adv. Sci. 3/2026)

Controlled Microdroplet Printing Electrospray systems have been widely utilized in biomedical, pharmaceutical,and materials science applications due to their ability to enable precise liquidmanipulation and efficient ionization. The cover represents a liquid metal-embedded electrospray deposition (LM-ESD) system that enables needle-free, electrospray-driven microdroplet printing with high precision and stability, achieved through integrated liquid metal electrodes. More details can be found in the Research Article by Jinsung Park, Gyudo Lee, Insu Park, and co-workers (DOI: 10.1002/advs.202510905).
