ZnO SiO2 Core Shell Nanoparticles: Nanoparticles can be categorized based on single or multiple materials into simple and core/shell or composite nanoparticles. In general, simple nanoparticles are made from a single material; whereas, as the name implies, composite and core/shell particles are composed of two or more materials. The core/shell type nanoparticles can be broadly defined as comprising a core (inner material) and a shell (outer layer material). These can consist of a wide range of different combinations in close interaction, including inorganic/inorganic, inorganic/organic, organic/inorganic, and organic/organic materials. The choice of shell material of the core/shell nanoparticles is generally strongly dependent on the end application and use. The core-shell nanoparticles have lots of importance in different important areas especially biomedical, pharmaceutical, and electronics. They also have application in drug delivery, in gas sensing, in pesticide sensing etc.

ZnO SiO2 Core Shell Nanoparticles: Various types of core-shell nanoparticles have been developed in outstanding efforts between academia and industry in the last decades. The core-shell nanoparticles exhibit improved physical and chemical properties over their single-component counterparts, and hence are potentially useful in a broader range of applications, for example, in pesticide sensing. In this application of core shell nanoparticles I found that these particles are more stable than the single nanoparticles and they are morphologically spherical in shape. The particle size of these particles is ̴ 300 nm. These characteristics of core-shell nanoparticles are measured by TEM, SEM, and the particle size is determined by the zeta sizer. Pesticide sensing is done by using long period fiber grating sensors for the applications in biological sensors for in vitro detection of pathogens and chemical sensors for environmental and industrial process monitoring.

ZnO SiO2 Core Shell Nanoparticles: Core shell nanoparticles are concentric spherical particles, which were the most common where a simple spherical core particle was completely coated by a shell of a different material. They are more effective than the single nanoparticles, because the nanoparticles will be oxidized with time, to protect the oxidization we use shell on the core. It also prevents the leakage of the core in drug delivery application. Core shell nanoparticles have better life because they are highly stable. They have high efficiency and good performance.

ZnO SiO2 Core Shell Nanoparticles: Core-shell nanoparticles are highly functional materials with modified properties. Sometimes properties arising from either core or shell materials can be quite different. The properties can be modified by changing either the constituting materials or the core to shell ratio. Because of the shell material coating, the properties of the core particle such as reactivity decrease or thermal stability can be modified, so that the overall particle stability and dispersibility of the core particle increases. Ultimately, particles show distinctive properties of the different materials employed together. The purpose of the coating on the core particle are many fold, such as surface modification, the ability to increase the functionality, stability, and dispersibility, controlled release of the core, reduction in consumption of precious materials, and so on.

ZnO SiO2 Core Shell Nanoparticles: The core-shell nanoparticles can be broadly defined as comprising a core and a shell. These can consist of a wide range of different combinations in close interaction, including inorganic/inorganic, inorganic/organic, organic/inorganic, and organic/organic materials. Core-shell nanoparticles are widely used in different applications such as biomedical and pharmaceutical applications, catalysis, electronics, enhancing photoluminescence, creating photonic crystals, etc. In particular in the biomedical field, the majority of these particles are used for bioimaging, controlled drug release, targeted drug delivery, cell labeling and tissue engineering applications.
