Recent advancements in hybrid electrochemical biosensors nanoarchitectronics

Nanobiosensors (NBSs) are forms of biosensors constituting of nanomaterials (NMs) (nanoparticulates and nanoarchitectures) embedment. Attributed to the peculiar predisposition of NMs features including elevated conductivity, along with physicochemically, electrochemically, optically, magnetically as well as mechanically affiliated properties, NBS exhibit reliability, precision and elevated sensitivity in biosensing strategies in comparison with traditional sensors exhibiting various forms of limitation during detecting activities. Presently, NMs are versatily utilized in a vast range of electrochemical sensorial uses because of their physically, chemically, as well as biologically inclined features, presenting them as outstanding materials for designing electrode surface for the construction of electrochemical sensors exhibiting outstanding analytical behavior. Hence, NBSs are referred as biosensors in synergy with nanotechnological strategies. Through NMs facilitation, electrochemical NBSs are prospective replacements for traditional approaches for food safety evaluation utilizing various sensing technologies for food examination including colorimetric, optical, and chromatographic technologies. Thus, carbon derivatives as well as other NMs improve sensitivity while reducing the detection limit through signal amplification while offering new mechanisms of signal transduction which effectively facilitates detection of very minimal levels of food contaminants, pathogens, etc. Hence, this paper depicts new trends in fabrication of electrochemical biosensor nanoarchitectronics for food safety analysis effective for detecting a vast range of biologically and chemically affiliated substrates in industrial food segment. Furthermore, the limitations and challenges inherent in designing electrochemical NBS nanoarchitectronics for food safety evaluation are additionally elucidated.
