“…Sonication is an effective technique for generating small liquid metal droplets, typically ranging from tens of nanometers to a few micrometers. [90] Ultrasonication is a process that employs sound waves to induce a vapor cavity that leads to the formation of liquid metal droplets within an aqueous medium [120,121] as shown in Figure 3d. The formation of the droplet is realized by the creation of localized hot spots in the bulk liquid induced by extremely high temperatures and pressures.…”

Liquid metals, particularly non‐toxic gallium‐based alloys, have emerged as promising materials for future soft electronics due to their unique properties, including fluidity, excellent electrical and thermal conductivities, and surface reactivity. They demonstrate adaptability, responsivity, and self‐healing abilities, offering a platform for innovative electronic devices. Embodied in a droplet form factor, gallium‐based liquid metal droplets (LMDs) combine the traits of liquid metals with the advantages of miniaturized structures, including high surface tension, high surface area, high mobility, and surface functionalization. This review discusses the inherent properties of LMDs, which have driven substantial research interest across various fields, such as sensors, robotics, electronic circuits, energy harvesters, drug delivery, and microfluidics systems, among others. Effective fabrication and processing techniques are detailed for LMDs, illustrating their role in applications previously challenging with conventional materials, such as reconfigurable, self‐healing, and transient electronics. Existing challenges and future directions in this growing field are discussed. This extensive review seeks to further the understanding of LMDs and their potential, offering a roadmap for their journey from a niche interest to a key material in various electronic devices.

“…The low-cost, easy-tomanufacture, and solution processability of MHPs, which attributes to their success in various applications [37]. Scalable synthesis techniques of perovskite nanocrystals (PNCs) are helping the industry to commercialize perovskite-based optoelectronic devices [38][39][40]. In our previous work, we have shown that luminescent perovskite nanomaterials can be synthesized by sonochemical methods, which is one of the cost-effective, simple, and efficient, scalable synthesis techniques [41].…”

Metal halide perovskites possess exciting optoelectronic properties and are being used for various applications, including fluorescent anticounterfeiting security tags. The existing anticounterfeiting based on perovskites have a reversible transition that does not allow to know whether the information is tampered or compromised. In this work, we developed fluorescent anticounterfeiting security tags using micropatterned metal halide perovskite nanocrystals. The micro features were created by spray coating of stabilized methylammonium lead tribromide (MAPbBr3) nanocrystals (NCs) in polystyrene (PS) solution, which has a proper wettability to various rigid and flexible substrates. The PS provides additional optical and structural stability to the MAPbBr3NCs against polar solvents. By combining stable and unstable MAPbBr3nanocrystals, we created a double-layer fluorescent anticounterfeiting security tag, and the information is hidden under both the ambient light and UV illumination. An irreversible decryption is possible after treating the security tags with particular solvents, thus tampering of the security tag is easily detectable.
