Abstract:

Rapid and effective diagnosis and treatment are critical for alleviating the hazards caused by ocular diseases. Taking advantages of their attractive merits including small dimensions, large ratios of surface-to-volume, good surface tailorability, and unique optical/electronic/mechanic properties, numerous kinds of nanomaterials have been utilized to construct high-performance nanoprobes. Of particular note, during the past decade, silicon nanomaterials featuring favorable biocompatibility have been explored as multifunctional nanoprobes for the high-efficacy detection and therapy of different ocular diseases. Herein, we intend to summarize recent achievements in silicon-based nanoprobes for diagnosing and curing ocular diseases, such as corneal diseases, retinal diseases and glaucoma. Firstly, we highlight the preparation of silicon-based nanoprobes and their biomedical applications in the detection and treatment of corneal diseases[e. g., corneal neovascularization(NV) and bacterial keratitis]. Secondly, we concentrate on the latest typical advancements of the synthesis and functionalization of silicon-based drug delivery systems, capable of imaging and treating retinal diseases(e.g., retinitis pigmentosa and retinal NV). Thirdly, we briefly outline the developments of multifunctional silicon-based drug delivery nanosystems and their in vivo bioapplications in the imaging analysis and treatments of glaucoma. In the final section, we further discuss the major challenges and prospects of silicon-based nanoprobes applying in the field of ocular diseases.
