“…Among them, graphene and its derivatives, graphene oxide (GO) and reduced graphene oxide (rGO) have been widely employed in electrochemical biosensing due to their remarkable electrical and mechanical properties. Their large surface-to-volume ratio, enriched oxygen content and efficient formation of nanocomposites with metal nanoparticles, metal oxides or polymers, make them advantageous in electrochemical sensing approaches [ 194 ].…”

Exosomes, a type of extracellular vesicles, have attracted considerable attention due to their ability to provide valuable insights into the pathophysiological microenvironment of the cells from which they originate. This characteristic implicates their potential use as diagnostic disease biomarkers clinically, including cancer, infectious diseases, neurodegenerative disorders, and cardiovascular diseases. Aptasensors, which are electrochemical aptamers based biosensing devices, have emerged as a new class of powerful detection technology to conventional methods like ELISA and Western analysis, primarily because of their capability for high-performance bioanalysis. This review covers the current research landscape on the detection of exosomes utilizing nanoarchitectonics strategy for the development of electrochemical aptasensors. Strategies involving signal amplification and biofouling prevention are discussed, with an emphasis on nanoarchitectonics-based bio-interfaces, showcasing their potential to enhance sensitivity and selectivity through optimal conduction and mass transport properties. The ongoing challenges to broaden the clinical applications of these biosensors are also highlighted.

“…The peculiar photochemical characteristics of GO make it a suitable sensor component toward a plethora of possible analytes, such as water and VOCs [ 43 ], glucose [ 44 ], antibiotics [ 45 ], and phytohormones [ 46 ], to name just a few. Its large surface area, flexibility, thermal stability, optical transparency and ease of production, coupled to nonconductive hydrophilic properties and proneness to functionalization, attracted a wide interest in the biosensing field [ 47 , 48 ].…”

Graphene oxide (GO) is a versatile material obtained by the strong oxidation of graphite. Among its peculiar properties, there is the outstanding ability to significantly alter the fluorescence of many common fluorophores and dyes. This property has been exploited in the design of novel switch-ON and switch-OFF fluorescence biosensing platforms for the detection of a plethora of biomolecules, especially pathological biomarkers and environmental contaminants. Currently, novel advanced strategies are being developed for therapeutic, diagnostic and theranostic approaches to widespread pathologies caused by viral or bacterial agents, as well as to cancer. This work illustrates an overview of the most recent applications of GO-based sensing systems relying on its fluorescence quenching effect.
