The widespread use of nano-aptasensors is seen in various clinical areas, drug discovery, the development of human health, and biological research. Variety in design practices, detection strategies, and areas of application remind us of the need for review, comparison, and classification of this type of sensors. The aptasensors and the attractiveness of using nanotechnology, like a wonderland, have attracted researchers’ attention. Furthermore, the application of these tools (rapid detection, quality control, and drug level assessment in the clinical and paraclinical settings) are of special importance. In this study, aptasensors have been reviewed and classified in terms of type, sensor approach, and transducer type, and in some cases, the advantages, disadvantages, and detectability of sensors have been described. To select, compare, and classify nano-aptasensors in the present research, the author sought to use nanotechnology, aptamer bioreceptor, and application field of these types of sensors, while considering the sensor’s ability. Nanotechnology have the high potential to reduce costs, save time, and increase the accuracy of detecting agents. Diversification in strategy, precedence of studies, and type of nano-processes itself are not considered as advantages; rather the simplicity, accuracy, user-friendliness, accessibility, and competitive cost of the sensor lead to the superiority of the nano-aptasensor.
