Electrochemical biosensors are contemplated as a preeminent subset of chemical sensors which have attracted considerable attention of the scientific community owing to their selective as well as prompt response towards targeted analytes, simplicity in design, devoid of cumbersome sample preparation procedures, and user affability. These types of sensors have opened a brighter avenue with many opportunities for disease diagnostics and frequent monitoring of human health status. Characteristically, electrochemical biosensors are the integration of three essential components which are the bio-recognition component for specific detection of any targeted analyte, a signal transducer generating a measurable response from the interaction of the targeted analyte with the bio-recognition component, and an electronic system for data administration.
Various electrochemical detection techniques, such as potentiometry, chronoamperometry, voltammetry, impedance analysis, field effect transistor (FET), etc. can be implemented for point of care (POC) based devices aligned to personalized healthcare management in the present century. Researchers are in quest of innovative materials for escalating the electrochemical performance of the devices in terms of improved recognition efficacy and detection limits (LODs). Recent trends in utilizing nanoscopic materials including in situ generated nanoparticles, nanotubes, nanowires, nano MOFs, nanopores, self-adhesive monolayers, quantum dots, nanocomposites, etc. can be improvised for the development of unprecedented electrochemical biosensors, an enigmatic offer of delivering the next-generation promising alternative in contemporary domain compare to existing conventional detection portfolios. In the realm of nanotechnology, advancement and versatilities in unconventional nanomaterials-based electrochemical signal amplifications have the flagship journey in order to touch the milestones which could have tremendous potential of escalating both sensitivity and selectivity of relevant sensors as well as biosensors in an impeccable stage. Furthermore, targeted advanced functional materials of the present century can impact a synergic effect in terms of catalytic activity, conductivity, and biocompatibility to accelerate signal transduction as well as in recognition events, ultimately invoking impact on amplifying bio-recognition events leading to highly sensitive biosensing. Tailor-make design of diverse nano-edifices can be developed to improve the performance as well as efficiency of dreamed sensors. Moreover, significant research in the contemporary domain based on the construction of nanocluster-modified electrode materials, coupled with numerous electrochemical methods, is advancing and spreading the potential application of electrochemical devices to a greater extent. The amalgamation of advanced features in a sensory system exhibits the key emergence in terms of high sensitivity as well as selectivity toward discerning detection of toxic gases, chemicals, biological metabolites, lethal ions, light, heat, etc. in consequence of their deadly environmental and biological impact.
