Smart Nanosensors

The term "nanosensor" originates from merging "nano" and "sensors." "Nano" is linkedwith nanotechnology, dealing with components sized in the nanometer range (۱۰^-۹ meters).The second term, "sensors," refers to devices measuring physical quantities and transmittingcorresponding signals interpreted by operators or instruments. Within nanoscience,nanosensors perform various roles: managing chemical and physical elements in challengingor remote environments, diagnosing biochemicals in cellular tissues, and measuring nanoscaleparticles in industries and surroundings. Nanosensors present notable advancements inselectivity, speed, and sensitivity compared to traditional sensing methods. These sensorsbridge nanoscale to macro-level worlds, detecting minuscule quantities down to parts perbillion (ppb) levels with remarkable precision.The sensors can be classified as nano-sensors if they meet the following criteria: their size iswithin the nanometer scale, their sensitivity is at the nanoscale, and their interaction withobjects is spatially confined within the nanometer scale.
