“…This material is known as periodic mesoporous organosilica (PMO) and exhibits some advantages compared to conventional MSNs, namely a high loading capacity and a uniform distribution of organic groups within the framework [ 67 ]. PMOs have shown a great potential in many applications such as optics [ 68 ], catalysis [ 69 ] and adsorption studies [ 70 ]. Figure 4 is a schematic summary of the post synthetic grafting process as well as both co-condensation methodologies.…”

A biomedical contrast agent serves to enhance the visualisation of a specific (potentially targeted) physiological region. In recent years, mesoporous silica nanoparticles (MSNs) have developed as a flexible imaging platform of tuneable size/morphology, abundant surface chemistry, biocompatibility and otherwise useful physiochemical properties. This review discusses MSN structural types and synthetic strategies, as well as methods for surface functionalisation. Recent applications in biomedical imaging are then discussed, with a specific emphasis on magnetic resonance and optical modes together with utility in multimodal imaging.

“…PMO materials are fundamentally unique thanks to the combination of all the advantages of a robust porous organic/ inorganic framework, along with the intrinsic properties of the organic fragments. 23,[52][53][54][55][56][57][58][59][60][61][62][63][64] On the one hand, PMO NPs thus share the numerous assets of mesoporous silica [65][66][67] such as:…”

Periodic Mesoporous Organosilica (PMO) nanomaterials are envisioned to be one of the most prolific subjects of research in the next decade. Similar to mesoporous silica nanoparticles (MSN), PMO nanoparticles (NPs) prepared from organo-bridged alkoxysilanes have tunable mesopores that could be utilized for many applications such as gas and molecule adsorption, catalysis, drug and gene delivery, electronics, and sensing; but unlike MSN, the diversity in chemical nature of the pore walls of such nanomaterials is theoretically unlimited. Thus, we expect that PMO NPs will attract considerable interest over the next decade. In this review, we will present a comprehensive overview of the synthetic strategies for the preparation of nanoscaled PMO materials, and then describe their applications in catalysis and nanomedicine. The remarkable assets of the PMO structure are also detailed, and insights are provided for the preparation of more complex PMO nanoplatforms.

“…SPE sorbents have been explored for the determination of inorganic (heavy metals) and organic (pesticides, hormones, etc.) contaminants in different samples [16][17][18][19][20][21][22]. In general, a common theme of these funtionalization strategies was attachment of the organic moiety by the post-synthesis (or grafting) method.…”
