“…Mukherjee and co-workers [ 77 ] reported the results of a study of an electrochemical sensor based on a hybrid material containing nitrogen-doped graphene nanosheets modified with 5,10,15,20-tetrakis(1-methyl-4-pyridino) porphyrin tetra( p -toluenesulfonate) by a low temperature hydrothermal method via non-covalent strategies. Due to its increased active surface area, which resulted in an increase in the number of reactive sites and low resistance, the prepared hybrid material had better sensitivity and selectivity toward nitric oxide compared to pristine graphene sheets and porphyrin.…”

“…An important step in the development of the sensor is also the method of modification of the electrode surface, which provides good adhesion and charge transfer between the active layer and the electrode surface. The methods, which are widely used for the modification of electrodes with phthalocyanine, porphyrins and hybrid materials, include immersion in the corresponding solution [ 56 ], drop and dry [ 59 , 64 , 77 , 78 ], electrodeposition or electropolymerization [ 58 , 73 , 74 ]. To prevent leaching of the electroactive component, the active layers are sometimes covered with a polymeric layer that does not prevent the penetration of analyte molecules.…”

Nitric oxide (NO) is a highly reactive toxic gas that forms as an intermediate compound during the oxidation of ammonia and is used for the manufacture of hydroxylamine in the chemical industry. Moreover, NO is a signaling molecule in many physiological and pathological processes in mammals, as well as a biomarker indicating the course of inflammatory processes in the respiratory tract. For this reason, the detection of NO both in the gas phase and in the aqueous media is an important task. This review analyzes the state of research over the past ten years in the field of applications of phthalocyanines, porphyrins and their hybrid materials as active layers of chemical sensors for the detection of NO, with a primary focus on chemiresistive and electrochemical ones. The first part of the review is devoted to the study of phthalocyanines and porphyrins, as well as their hybrids for the NO detection in aqueous solutions and biological media. The second part presents an analysis of works describing the latest achievements in the field of studied materials as active layers of sensors for the determination of gaseous NO. It is expected that this review will further increase the interest of researchers who are engaged in the current level of evaluation and selection of modern materials for use in the chemical sensing of nitric oxide.

“…Furthermore, the blood compatibility studies demonstrated that PFNGS were hemocompatible. 269 Due to their versatile properties, GQDs can be extensively used in a variety of biological applications such as nanomedicine (e.g., drug delivery), bio-sensing, and bio-imaging. However, it is important to determine the cellular uptake, circulation, and cytotoxicity of unmodified GQDs, functionalized GQDs, and doped GQDs before their use as conjugating materials.…”

“…Another study [ 133 ] demonstrated that a low-temperature hydrothermal process can be effectively used to prepare porphyrin–graphene hybrids that serve as biocompatible and reusable sensors. Such nanomaterials were able to detect nitric oxide (NO), with good sensitivity (3.6191 μA μM −1 ) and electrocatalytic properties (0.61 V) in comparison to starting, reference materials.…”

Interest in the development of graphene-based materials for advanced applications is growing, because of the unique features of such nanomaterials and, above all, of their outstanding versatility, which enables several functionalization pathways that lead to materials with extremely tunable properties and architectures. This review is focused on the careful examination of relationships between synthetic approaches currently used to derivatize graphene, main properties achieved, and target applications proposed. Use of functionalized graphene nanomaterials in six engineering areas (materials with enhanced mechanical and thermal performance, energy, sensors, biomedical, water treatment, and catalysis) was critically reviewed, pointing out the latest advances and potential challenges associated with the application of such materials, with a major focus on the effect that the physicochemical features imparted by functionalization routes exert on the achievement of ultimate properties capable of satisfying or even improving the current demand in each field. Finally, current limitations in terms of basic scientific knowledge and nanotechnology were highlighted, along with the potential future directions towards the full exploitation of such fascinating nanomaterials.
