There are many benefits to using this Co-MCM-41 heterogeneous catalyst in sophisticated oxidation processes [36]. Co-MCM-41 mesoporous materials have been synthesised, and their high specific surface area, well-ordered mesoporous structure, large surface area, and flexible framework make it easy to incorporate metal active sites in silica materials [37, 38]. These materials also make good dispersions for reaction and product molecule molecules. The host material's adsorption characteristics are crucial for the purification of biomolecules. According to a publication, MCM-41 with Co inserted is a strong contender for use as a high surface area adsorbent for

biological compounds like amino acids [39]. This has undergone testing as a method of regulated drug release for medications like ibuprofen [40]. These heterogeneous catalyst Co-MCM-41 based mesoporous materials have successfully immobilised or absorbed a number of proteins, including cytochrome C [41], lysozym [42], and trypsin [43], and their activities have been investigated [44]. Well-ordered mesoporous silica nanoparticles have recently been demonstrated to be useful as cell markers by Lin et al. [45].
