A simple method is proposed for the synthesis of noble metal M@YSiO (M = Au, Pd, Ag) yolk-shell nanoparticles. The effects of synthesis conditions on the preparation of yolk-shell nanoparticles were discussed in detail. According to the different corrosion resistances between inorganic silica and organosilicone in a selective etching solution, yolk-shell nanoparticles with large cavity and thin shell were prepared using the same aqueous medium in a step-by-step synthesis process. Different from traditional methods, this method is facile and efficient because the main synthesis process is carried out in an aqueous phase. This extended method may benefit the synthesis and application of other nanomaterials with a similar yolk-shell structure.

Emulsion interface engineering has been widely employed for the synthesis of nanomaterials with various morphologies. However, the instability of the liquid-liquid interface and uncertain interfacial interactions impose significant limitations on controllable fabrications. Here, we developed a liquid-nano-liquid interface-oriented anisotropic encapsulation strategy for fabricating asymmetric nanohybrids.

Near-infrared (NIR) persistent luminescence nanoparticles (PLNPs) have significant potential in diagnostic and therapeutic applications owing to their unique persistent luminescence (PersL). However, obtaining high-performance NIR PLNPs remains challenging because of the limitations of current synthesis methods. Herein, we introduce a spatial confinement growth strategy for synthesizing high-performance NIR PLNPs using hollow mesoporous silica (hmSiO).

Solar interfacial evaporation (SIE) has emerged as a highly promising approach for sustainable freshwater harvesting. However, maintaining a stable evaporation rate and achieving a high freshwater yield in high-salinity brines remain a significant challenge. In this study, we present the development of silicone sponge-based evaporators with a "free-salt" structure, designed to enhance the efficiency of SIE and freshwater collection.

Fentanyl and its analogs have emerged as the main factor behind the ongoing opioid abuse globally in recent years. However, the existing techniques for sensitive and accurate detection of fentanyl are often complex, laborious, expensive, and restricted to central healthcare facilities. We reported herein a plasmonic biochip fabricated by the femtosecond laser-induced nanostructures and plasmonic nanomaterials for sensitive SERS-based detection of fentanyl.

In this work, we demonstrate a straightforward and versatile approach for fabricating flexible SERS substrates for highly sensitive fentanyl detection. Our design strategy integrates the synthesis of a yolk-shell structured plasmonic nanomaterial with a flexible cellulose substrate. The resulting SERS platform demonstrates excellent sensing capabilities, achieving a fentanyl detection limit as low as 4.
