Summary: By nanoengineering liquid metal nanoparticles and using galvanic replacement, diverse core-shell nanostructures including LM@Au, Au@Ga oxide, and hollow Ga oxide nanoparticles are successfully fabricated. LM@Au exhibits exceptional photothermal performance with a conversion efficiency of 65.9%, which is five times that of gold nanoparticles. The high photothermal conversion efficiency and biocompatibility of LM@Au show promising applications in hyperthermia cancer therapy.

Summary: This study presents a general route for programmable preparation of complex core-shell nanostructures using liquid metal droplets as reformable templates. By triggering a localized galvanic replacement reaction in an ultrasonication system, high-level compositional diversity control and quantitative regulation of both the core and shell layers of the heterogeneous products are achieved, offering a method that cannot be realized with a solid-template synthetic route.

Summary: In this study, different types of ZnO-based nanocomposites were fabricated and characterized. The etching of ZnO nanorods increased the surface area and defect concentration, while sulfurization of the ZnO/ZnS nanotubes reduced defects and improved surface roughness. The results indicate that ZnO and ZnO/ZnS nanotubes hold promise for sensing device applications.

Summary: Biopolymer-based microgels with a narrow size distribution, fabricated using protein-polysaccharide segregative phase separation method, show potential applications in stable emulsions. The core-shell structure of the microgels, with a densely cross-linked protein network as the core and a polysaccharide hairy layer as the shell, resembles casein micelles and contributes to their functional properties. The convenient fabrication method without toxic reagents or high energy input makes these size-controllable microgels suitable for a wide range of industries.

Summary: ZnO/ZnMgO core/shell nanorod arrays, fabricated using hydrothermal and radio frequency magnetron sputtering methods, exhibit significant ohmic contact and high photo-to-dark current ratio, with fast rise and decay times under 254 nm and 365 nm illumination. The core/shell nanostructure facilitates the rapid separation of photogenerated electron-hole pairs and suppresses recombination of carriers, making it a promising candidate for future ultraviolet detection applications.

Summary: Researchers have successfully synthesized a core-shell CDT drug FeCNB, which achieves high-efficiency CDT under physiological pH conditions through the galvanic cell structure formed in physiological electrolyte solution. FeCNB not only has T2-magnetic resonance imaging function and photothermal conversion ability, but also improves the CDT effect through tumor heating to achieve a satisfactory synergistic photothermal therapy (PTT)/CDT outcome.

Summary: A thorough investigation was performed to unveil the shell effect on lifetime-based thermal sensitivity modulation by finely controlling the shell thickness of lanthanide-doped core-shell-shell nanoparticles. The study showed that both active and inert shells can regulate the thermal dependent nonradiative decays and NIR luminescence lifetime of Yb3+, which in turn modulates the thermal sensitivity. The modified nanoprobes possessed robust stability to fluctuations in the microenvironment, enabling accurate temperature mapping in living mice.

Summary: Developing core-shell nanoparticles with an inert shell can improve the luminescence performance by protecting the luminescent core from quenching influences. This study investigates the migration of Er3+ and Yb3+ ions in LiLuF4 and LiYF4 hosts and explores how to hinder this migration. Different synthesis routes were explored, and a LiYF4 inert shell was grown around a 2%Er,18%Yb:LiLuF4 core to form a heterogeneous core-shell system. The results show significantly less ion migration in the heterogeneous core-shell structures compared to the homogeneous ones.

Summary: A novel strategy using galvanic displacement-based substrates for identifying anthraquinone dyes through surface enhanced Raman spectroscopy (SERS) is presented. The use of silver microparticles, particularly dendritic ones, formed by reducing silver nitrate with zinc or copper, allows for a quick and cost-effective SERS analysis within 20 minutes. Textile fibers can be covered almost instantaneously with the substrates once the galvanic displacement reaction is triggered.

Summary: This study presents a general approach for systematically fabricating core-shell nanohybrids using liquid-metal Ga alloys as templates. A local galvanic replacement reaction is initiated using an ultrasonic system. Controlled and quantitative regulation of non-homogeneous nanoparticle shell layer composition is achieved, and the resulting core-shell nanostructures are used as efficient microwave absorbers. This strategy enables the future fabrication of functional materials through spontaneous interfacial redox reactions.
