“…Especially graphene oxide (GO), which is a one‐atom‐thick graphene fragment that possesses hydroxyl and epoxide functional groups in the basal plane and carbonyl and carboxyl groups at the edges. GO presents many distinguished advantages, such as facile preparation, mass production, easy chemical modification, interfacial activities, and low cost . In addition, reduced GO (RGO) is not only decorated with multiple oxygen‐containing functional groups but can also restore the good electronic, thermal, and mechanical properties of graphene.…”

MicroRNAs (miRNAs) are short, endogenous, noncoding RNAs that play critical roles in physiologic and pathologic processes and are vital biomarkers for several disease diagnostics and therapeutics. Therefore, rapid, low‐cost, sensitive, and selective detection of miRNAs is of paramount importance and has aroused increasing attention in the field of medical research. Among the various reported miRNA sensors, devices based on graphene and its derivatives, which form functional supramolecular nanoassemblies of π‐conjugated molecules, have been revealed to have great potential due to their extraordinary electrical, chemical, optical, mechanical, and structural properties. This Review critically and comprehensively summarizes the recent progress in miRNA detection based on graphene and its derivative materials, with an emphasis on i) the underlying working principles of these types of sensors, and the unique roles and advantages of graphene materials; ii) state‐of‐the‐art protocols recently developed for high‐performance miRNA sensing, including representative examples; and iii) perspectives and current challenges for graphene sensors. This Review intends to provide readers with a deep understanding of the design and future of miRNA detection devices.

“…Moreover, traditional methods like coprecipitation method, solvent exchange method, and surfactant‐assisted self‐assembly, etc. can also be used to fabricate the well‐defined π‐conjugated compound materials by simply mixing host solvent with guest solvent without additional help, those aggregations have been wildly applied for detecting target analyst . Thanks to these advantages, organic electronics are currently becoming comparable to or even in sometimes beginning to surpass corresponding inorganic photoelectric devices not only in their performances but also with respect to their cost.…”

Sensors have attracted particular attention as analytical devices because of their importance in health and security. The ability to obtain unique functions using molecular design have rapidly advanced the use of organic optoelectronic materials of π‐conjugated compounds in electronic sensing devices. A brief introduction to sensors, focusing on organic micro‐ or nanoassemblies created using state‐of‐the‐art protocols for assembly and their recent development for high‐performance electronic sensing devices, is presented.

“…Several methods can be used to assemble porphyrin derivatives, as template-directed, surfactant-assisted, and deposition methods or pH-induced self-assembly protocol, among others [15][16][17][18][19][20][21][22][23][24][25][26]. Over the course of our studies focused on the development of amphiphilic porphyrin-based supramolecular systems, we largely used the "good-bad" solvent self-assembling method, by which macrocycles are at first molecularly dissolved in a good solvent and then a bad solvent is added to trigger the aggregation process.…”

Owing to the attractive potential applications of porphyrin assemblies in photocatalysis, sensors, and material science, studies presently concerning porphyrin aggregation are widely diffused.π-π stacking, H-bonding, metal coordination, hydrophobic effect, and electrostatic forces usually drive porphyrin interaction in solution. However, theoretical studies of such phenomena are still limited.Therefore, a computational examination of the different porphyrin aggregation approaches is proposed here, taking into account amphiphilic [5-{4-(3-trimethylammonium)propyloxyphenyl}-10,15,20-triphenylporphyrin] chloride, whose aggregation behavior has been previously experimentally investigated. Different functionals have been adopted to investigate the porphyrin dimeric species, considering long-range interactions. Geometry optimization has been performed, showing that for the compound under analysis, H-type and cation-π dimers are the most favored structures that likely co-exist in aqueous solution. Of note, frontier orbital delocalization showed an interesting interaction between the porphyrin units in the dimer at the supramolecular level.
