Hybrid Silica‐Coated Nanomaterials: Pioneering Breakthroughs in Biomedical Technology

ABSTRACT The field of biomedicine has extensively studied silica‐coated organic/inorganic nanoparticles due to their remarkable properties, such as biocompatibility, chemical stability, ease of functionalization, and thermal stability. Silica has been utilized to coat or encapsulate organic/inorganic nanoparticles, providing protection against aggregation and acid leaching while improving cytocompatibility. This review provides an overview of the manufacturing methods for silica nanoparticles, with a specific focus on surface strategies for core template nanomaterials (both hard and soft templates). These strategies involve the use of chemicals or biomolecules to guide nucleation and growth of silica at the interface of two phases. Furthermore, recent advancements in silica‐coated nanoparticles are discussed, emphasizing their applications in various areas such as bioimaging, drug delivery, biosensors, phototherapy, and hyperthermia.
