“…Gunji accomplished this through a platinumcatalyzed hydrosilylation of C 60 followed by the co-condensation of the precursor with TEOS. 22 The resultant monoliths contained a Si:C 60 mole ratio in the range or 500-2000, in which the C 60 moieties were homogeneously distributed throughout the material, a feat which could not be accomplished through the use of unmodified C 60 . Similarly, Tang used a hydroamination reaction to create a similar material, in which he was able to make transparent glasses with C 60 concentrations ranging from 0.02 to 0.55 wt %.…”

Here we report the first documented synthesis of a periodic mesoporous organosilica (PMO), that contains a multiply bonded C60 moiety integrated into the silica channel walls of the material, dubbed C60-PMO. This is accomplished through the acid-catalyzed co-assembly, of C60(NHCH2CH2CH2Si(OEt)3)x and tetraethylorthosilicate (TEOS) with a polyethyleneoxide-polylpropyleneoxide-polyethyleneoxide triblock copolymer template. The percentage of C60 in the final material was estimated to be a minimum of 63 vol %, but potentially as high as 91 vol %. The effects of the synthesis conditions on the mesostructure of the resulting materials are examined. In particular, we demonstrate that the C60 is uniformly distributed throughout the entire sample by the use of energy dispersive X-ray fluorescence (EDX) analysis and an OsO4 label bonded to the C60.

“…They are classified according to their chemical composition into hybrid silica-based monoliths and hybrid polymer-based monoliths. Hybrid polymer-based monoliths are prepared via matrix functionalization through chemical bonding, allowing the preservation of specific structures for the functional groups [ 35 , 36 ]. On the contrary, silica-based monoliths are synthesized via the sol–gel process utilizing a silica precursor with organic moieties [ 37 ].…”

The increasing demand for highly pure biopharmaceuticals has put significant pressure on the biotechnological industry to innovate in production and purification processes. Nucleic acid purification, crucial for gene therapy and vaccine production, presents challenges due to the unique physical and chemical properties of these molecules. Meeting regulatory standards necessitates large quantities of biotherapeutic agents of high purity. While conventional chromatography offers versatility and efficiency, it suffers from drawbacks like low flow rates and binding capacity, as well as high mass transfer resistance. Recent advancements in continuous beds, including monoliths and cryogel-based systems, have emerged as promising solutions to overcome these limitations. This review explores and evaluates the latest progress in chromatography utilizing monolithic and cryogenic supports for nucleic acid purification.

This review presents an overview of the properties of hybrid organic–inorganic monolithic materials and summarizes the recent developments in the preparation and applications of these hybrid monolithic materials. Hybrid monolithic materials with porosities, surface functionalities, and fast dynamic transport have developed rapidly, and have been used in a wide range of applications owing to the low cost, good stability, and excellent performance. Basically, these materials can be divided into two major types according to the chemical composition: hybrid silica‐based monolith (HSM) and hybrid polymer‐based monolith (HPM). Compared to the HPM, HSM monolith has been attracting most wide attentions, and it is commonly synthesized by the sol–gel process. The conventional preparation procedures of two type's hybrid organic–inorganic monoliths are addressed. Applications of hybrid organic–inorganic monoliths in optical devices, capillary microextraction (CME), capillary electrochromatography (CEC), high performance liquid chromatography (HPLC), and chiral separation are also reviewed.
