“…Numerous analytical methods for determination of organic compounds were developed by utilization of porphyrins: e.g. for nucleic acids [28,42,57,58,59] (porphyrin exciton coupled circular dichroism [57] for other chiral agents too), aminoacids and proteins [48,60,61], carbohydrates [28,62,63], phenols and chlorophenols [64], phenolic endocrine compounds [65], hormones [66], non-ionic surfactants [67], phospholipids [68], sulphur-containing hydrocarbons [48,69], and explosives [70]. Most of these analytical methods are based on the spectrophotometric properties (absorption, light scattering and fluorescence) of porphyrins, therefore in this work we would like to summarize and complement the knowledge in this area of porphyrin-chemistry from analytical aspects.…”

We investigated the UV-Vis absorption, singlet-1 and singlet-2 fluorescence, as well as the formation of several metalloporphyrins from equilibrial and kinetic aspects in aqueous solution. Among these complexes were numerous typical out-of-plane and several in-plane metalloporphyrins, and between the two categories, a few border-line cases. On the basis of our results, we have complemented the categorization introduced by Barnes and Dorough for the metalloporphyrins. According to our observations, also in metalloporphyrins, the distortion, i.e., the planarity or nonplanarity of the macrocycle, is basically responsible for the spectral characteristics, while the electronic structure of metal center is a secondary factor, with a considerable importance mainly in the in-plane complexes. The type of complexes can be spectrophotometrically determined on the basis of their UV-Vis absorption and fluorescence spectra. Beside the spectral and photophysical effects of metalation, also those of the structural distortions were studied, which can originate also from metalation, protonation or overcrowded peripheral substitution of the free-base porphyrins, as well as from the axial ligation of metalloporphyrins. Our observation may be useful for different spectrophotometric analytical detection and determination methods, e.g. size-selective metal detection using free-base porphyrins (or other ringed chelate ligands), as well as the determination of Lewis bases as potential axial ligands, using metalloporphyrins.

“…Nonfunctionalized graphene presents an inert chemical surface. By contrast, the functional moieties located at the edges of GNRs facilitate the adsorption of molecules by π-π stacking, electrostatic, hydrogen bonding, and covalent interactions 22 . A handful of studies have examined the use of GNRs in electrochemical sensing applications.…”

“…The acceptable relative standard derivation (relative standard deviation, n = 6) and recovery certified its practicable application. Additionally, the graphene-porphyrin nanohybrid electrode could be applied to detect dissolved oxygen, (158) DNA, (159) and adenosine triphosphate (ATP) (160) by taking advantage of the synergistic effect.…”

Owing to the outstanding conductivity and biocompatibility as well as numerous other fascinating properties of graphene, graphene-based nanohybrids have shown unparalleled superiorities in the field of electrochemical biosensors. We provide a general overview of recent advances and state-of-the-art works related to all types of nanomaterial, including noble metals, transition metals, organic and inorganic dyes, polymers, biomolecules, ionic liquids (ILs), and boronic acid derivatives, applied to functionalize graphene to construct electrochemical biosensors. We are highlighting here types of functionalization, assembly procedures, roles of nanomaterial, and assay strategies. Finally, some future perspectives and possible research directions are also discussed.
