Evolution and present scenario of multifunctionalized mesoporous nanosilica platform: A mini review

The development of nanomaterials in the field of biomedical has attracted much attention in the past decades. New mesoporous nanosilica (MNS) generation, called multi functionalized MNS, presents the promising applications for efficient encapsulation, controlled release, and intracellular delivery of therapeutic agents due to their unique physiochemical properties, such as large surface area and pore volume, tunable particle size, biocompatibility, and high loading capacity. In this review, we intensively discussed the multi functionalized MNSs that respond to the demand of physical stimuli (thermo, light, magnetic field, ultrasound, and electricity), chemical stimuli (pH, redox, H₂O₂), and biological stimuli (enzyme, glucose, ATP), individual or in combination. Moreover, the recent applications of multi functionalized MNSs, focusing on drug and other therapeutic agents delivery, diagnostic imaging, and catalysis are also summarized in order to promote the further development of MNSs as a universal platform in the bright upcoming future.
