A biosensor is an integrated receptor-transducer device, which can convert a biological response into electrical signal. The design and development of biosensors have taken center stage for researchers or scientists in the recent decade owing to wide range applications, such as health care disease diagnosis, environmental monitoring, water food quality drug delivery. main challenges involved progress are (i) efficient capturing biorecognition signals transformation these electrochemical, electrical, optical, gravimetric, acoustic (transduction process), (ii) enhancing transducer performance i.e., increasing sensitivity, shorter time, reproducibility, low detection limits even detect individual molecules, (iii) miniaturization biosensing devices using micro-and nano-fabrication technologies. Those be met through integration sensing technology with nanomaterials, from zero- three-dimensional, possessing high surface-to-volume ratio, good conductivities, shock-bearing abilities, color tunability. Nanomaterials (NMs) employed fabrication nanobiosensors include nanoparticles (NPs) (high stability carrier capacity), nanowires (NWs) nanorods (NRs) (capable sensitivity), carbon nanotubes (CNTs) (large surface area, thermal conductivity), quantum dots (QDs) (color tunability). Furthermore, nanomaterials themselves act transduction elements. This review summarizes evolution biosensors, types based on their receptors, transducers, modern approaches NPs (e.g., noble metal oxide NPs), NWs, NRs, CNTs, QDs, dendrimers advancement expansion nanotechnology.
