Internal Structure of the Sensor

        By the structure of the core shell nanosensors were fabricated by using the self-assembly of the molecular and according to the techniques of the evaporation. The nanoparticles which are closely packed and it can exhibit the properties of the fine optical that are useful for sensing the biochemical. The Nano sensors and there RIS refractive index sensitivity can be detected by differentiating the refractive index for medium surroundings as well as the length of the nanosensiors which was investigated by using the assembly of the multilayer as polyelectrolyte which is arranged layer by layer.

        It is shown by the results shell thickness plays an important role for determining the RIS according to the length of the decay. The localized surface plasmon resonances (LSPR) are used as the base of the system for sensing which is constructed for the study. It can detected as 10mg/mL by using the core-shell nano-sensors which is provide the atrazine solution as well as it is well suitable detecting the pesticide.

        For the depositing the technology in spin coating it is fabricated by the α, β, γ rays which known as the convince Nano sensor for the core shelling in the different types of the LSPR. For producing the process of the sensor there are two key elements which are used in this process. It includes the concentration for the PS which must be appropriate for the step of the spin coating, if it would not be than the PS will be clump and it cannot be able to forming the large area of the uniform monolayer. These slides are going to dip in the water which must be very slow due to the connection of the strength which is occur between particles of PS as very weak according to the LSPR nanosensors.

        LSPR nanosensors are of three types including α type, β type, and γ type. The α type sensor mainly consists of 30 nm Au shell that is developed on 590 nm monolayer consisting of closely-packed PS and the structure is supported over a glass slide. On the other hand, β type sensor was composed of 60 nm Au shell that was developed on 590 nm. The structure was composed of closely-packed PS monolayer and generated on the glass slide [3]. The γ type sensor is somehow similar to the a-type sensor as 30 nm Au shell structured on 590 nm monolayer and composition was similar to both a-type and b-type nano sensor that is closely-packed PS and supported over 5 nm [3].
