“…Not limited to these representative materials, novel mesoporous silica materials with unique structures and properties have been continuously proposed. In addition, functionalization of mesoporous silica through co-condensation (direct synthesis) and grafting (post-synthesis) has been widely researched (Figure 4.1) [52].…”

Various functional systems have been developed using artificially constructed structures and synthesized compounds, and the nanotechnology based on them has recently received much attention. However, current nanoscale technologies are still highly inferior to those seen in natural systems. The efficiency of the energy conversion that occurs in mitochondrial and photosynthetic systems far exceeds that obtained in artificial systems. A dog can smell and a bat can hear far more sensitively than most artificial sensors. The information processing exhibited by the brain and nervous systems is much more sophisticated than that exhibited by current computers. Nature developed superior nanotechnologies to our own several billion years ago. Therefore, the use of biomaterials for the development of various functional systems can be a very practical approach to reaching several goals in current nanotechnologies.Unfortunately, biomolecules in most cases give their best performance under ambient conditions and are not mechanically and thermally strong enough to be used in harsh conditions. In order to overcome such difficulties, hybridization of biomolecules with supporting materials such as lipid assemblies, polymers and inorganic materials has been proposed to attain both biological functions and mechanical stability . Biomolecules are frequently immobilized on silica supports through a sol-gel process. As advanced silica structures, mesoporous silica molecular sieves and related materials have received much attention as inorganic supports for biomolecules [31][32][33][34][35][36][37][38][39][40]. Mesoporous silica materials are chemically and mechanically stable and resistant to microbial attack. In addition, chemical modification to introduce organic functional groups to the inner silica pore wall is highly possible. Outstanding properties of the mesoporous structure also lie in their high specific surface area and huge specific pore volume, which are definitely advantageous for the efficient accommodation of biomolecules. In addition, the narrow pore size distribution could provide reliable immobilization of biomolecules. According to the j113 Bio-inorganic Hybrid Nanomaterials. Edited

“…Mesoporous materials such as mesoporous silica and mesoporous carbon could satisfy such demands, because these materials possess well-defined pore structures in regular geometry. Their pore diameters are defined in the range 2-50 nm [99][100][101][102][103][104][105]. These materials have attracted much attention due to commercial interest in their use as catalysts, catalyst supports and in the adsorption of biomolecules owing to their large specific surface area, large specific pore volume and large pore diameter.…”

“…Because chemical modifications of mesoporous materials (especially mesoporous silica) are well established [297], further fabrication and functionalization of mesoporous materials has been extensively researched. Recent breakthroughs on fabrication of mesoporous materials involved synthesis of chiral mesoporous silica materials and preparation of periodic mesoporous organosilicates (PMO).…”

The controlled fabrication of nanometer-scale objects is without doubt one of the central issues in current science and technology. However, existing fabrication techniques suffer from several disadvantages including size-restrictions and a general paucity of applicable materials. Because of this, the development of alternative approaches based on supramolecular self-assembly processes is anticipated as a breakthrough methodology. This review article aims to comprehensively summarize the salient aspects of self-assembly through the introduction of the recent challenges and breakthroughs in three categories: (i) types of self-assembly in bulk media; (ii) types of components for self-assembly in bulk media; and (iii) self-assembly at interfaces.
