Medical forensics and homeland security have been focusing on the food and beverage industries, for water quality remote sensing, drug residue determination in food, etc. NT is playing a growing role in BS development. NT-based BS, also known as NBS technology, are reshaping the medical field. They are used in metabolite measurement, diabetes monitoring, and other applications, such as environmental protection. Pesticide and heavy metal ions detection in river water, as well as genomes sequencing the use of NM in BS design have increased their sensitivity and ability to also develop NP special properties, such as high electrical conductivity, improved shock resistance, sensitive response and flexibility. These advances result from the confluence of NP characteristics, allowing for the presentation of numerous modern flag transduction innovations in BS, such as the development of devices, and forms for manufacturing them and enhancing their measurement capability. Imaging the nanoscale objects has improved sensors connected with tiny atoms. Many mechanical devices, optical resonators and bi-functional architecture based on NBS have been developed. BS have also been discussed in this research, in order to highlight their critical applications in a variety of fields. This study discusses the various types of BS that depend on multiple types of NM, as well as their biological and implicational factors and analytical techniques, such as amperometric, CV potentiometric optical techniques, and other measurements methods that use enzyme and non-enzymatic BS.

Keywords : NT application; NBS; BS analytical techniques; enzyme BS; nanoenzymatic sensors.
