Controllable synthesis of versatile mesoporous organosilica nanoparticles as precision cancer theranostics. Biomaterials 2020; 256:120191. [PMID: 32593907 DOI: 10.1016/j.biomaterials.2020.120191] [Citation(s) in RCA: 47] [Impact Index Per Article: 11.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2019] [Revised: 05/18/2020] [Accepted: 06/09/2020] [Indexed: 12/16/2022]
Abstract
Despite the advantages of mesoporous silica nanoparticles (MSNs) in drug delivery, the inherent non-biodegradability seriously impedes the clinical translation of inorganic MSNs, so the current research focus has been turned to mesoporous organosilica nanoparticles (MONs) with higher biocompatibility and easier biodegradability. Recent remarkable advances in silica fabrication chemistry have catalyzed the emergence of a library of MONs with various structures and functions. This review will summarize the latest state-of-the-art studies on the precise control of morphology, structure, framework, particle size and pore size of MONs, which enables the precise synthesis of MONs with suitable engineering for precision stimuli-responsive drug delivery/release, bioimaging and synergistic therapy. Besides, the potential challenges about the future development of MONs are also outlooked with the intention of attracting more researchers to promote the clinical translation of MONs.

Space-Confined Polymerization: Controlled Fabrication of Nitrogen-Doped Polymer and Carbon Microspheres with Refined Hierarchical Architectures. ADVANCED MATERIALS (DEERFIELD BEACH, FLA.) 2019; 31:e1807876. [PMID: 30843288 DOI: 10.1002/adma.201807876] [Citation(s) in RCA: 67] [Impact Index Per Article: 13.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/05/2018] [Revised: 02/12/2019] [Indexed: 05/17/2023]
Abstract
The construction of refined architectures plays a crucial role in performance improvement and application expansion of advanced materials. The synthesis of carbon microspheres with a refined hierarchical structure is still a problem in synthetic methodology, because it is difficult to achieve the necessary delicate control of the interior structure and outer shell across the microscale to nanoscale. Nitrogen-doped multichamber carbon (MCC) microspheres with a refined hierarchical structure are realized here via a surfactant-directed space-confined polymerization strategy. The MCC precursor is not the traditional phenolic resol but a new kind of 2,6-diaminopyridine-based multichamber polymer (MCP) with a high nitrogen content up to 20 wt%. The morphology and sizes of MCP microspheres can be easily controlled by a dual-surfactant system. The as-synthesized MCC with a highly microporous shell, a multichamber inner core, and beneficial N-doping can serve as a promising supercapacitor material.
