“…7). AFM analysis showed that the behavior of the cobalt porphyrin is in accordance with our previous studies [17,26] regarding the morphology and aggregation architectures of porphyrin derivatives from different solvents. The nanosized particles of Co-3OHPP are evenly oriented, have the shape of uniform triangular lamels and are displayed at different depths (Fig.…”

“…Encouraged by our previous results in H 2 O 2 and CO 2 detection using porphyrins in combination with various inorganic/polymeric matrices [17,18], the next step of this research was to create a new sensitive material, that can optically or electrochemically detect minute quantities of H 2 O 2 (in the range of 5-35 µM, representing relevant levels in human physiology) and which might easily be incorporated in a detection device. Gold nanoparticles smaller than 20 nm in which total extinction is nearly all contributed by absorption [19] have been functionalized with Co(II) 5,10,15,20-meso-tetra(3-hydroxyphenyl) porphyrin ( Fig.…”

A hybrid formed between Mn(III) tetratolyl-porphyrin chloride (MnTTPCl) and spherical gold colloid (n-Au), MnTTPCl/n-Au, was tested along with its component nanomaterials as promising candidates in the detection of β-carotene from ethanol solutions. Among the investigated nanomaterials, the largest β-carotene concentration interval detectable by UV-Vis spectrophotometry (9.80 × 10 −6 M-1.15 × 10 −4 M) was obtained when using the MnTTPCl/n-Au hybrid. is hybrid material gives rise to the widest absorption band, covering the range of 425 nm to 581 nm after treatment with β-carotene.

Functionalized mesoporous silica materials (MSMs) are extensively investigated in sensing science due to their diverse structural and optical properties including tunable pore size, modifiable surface properties, and excellent accessibility to active sites. In the last few years, great efforts have been devoted to developing modification methods for MSMs for sensing applications with augmented sensitivity, super selectivity, as well as targeting capability, and multimodal capabilities. The functional group, structure, morphology, and component levels in the assembly of heterostructures of MSMs are a key for high sensing performance. As the development of mesoporous silica‐based sensing materials progresses, diverse functional units and materials are rationally implemented into the mesoporous structures. These heterostructures can maintain the excellent structural features of mesoporous silica and the optical properties of the functional units simultaneously, which shows the advantages of photostability, design flexibility, and multifunctionality. Here, an up‐to‐date overview of the fabrication strategies, the properties, and the sensing mechanisms of optical heterostructures based on MSMs is provided. A number of crucial sensing domains, including ionic, molecules, temperature, and biological species are highlighted. Finally, the prospects and potential sensing applications of mesoporous silica‐based optical heterostructures are discussed.
