Luminescent silica nanoparticles (LSNs) have broad applications because of their enhanced chemical and thermal stability. Nanoparticles have become an area of intense scientific research due to the broad range of potential applications in the optical, biomedical and electronic fields. Nanoparticles can be in the form of nanocrystals, nanopowders or nanoclusters.

These particles have been widely used in various biomedical applications and drug delivery systems Haider A, Kang IK (2015) Preparation of silver nanoparticles and their industrial and biomedical applications: a comprehensive review. nanoparticles and their applications – a mini review M.

Nanomaterials in the size range of 3–50 nm have received increased attention in the last few decades because they exhibit physical properties that are intermediate to those of individual molecules and bulk materials. The optical-electronics properties of gold nanoparticles are being explored widely for use in high technology applications such as sensory probes, electronic conductors, therapeutic agents, organic photovoltaics, drug delivery in biological and medical applications, and catalysis. Among nanoparticles, gold nanoparticles demonstrate special advantages in this field due to their unique properties, small size and high surface area-to-volume ratio. The particles act as a bridge between bulk materials and atomic or molecular structures. These sound waves are transmitted through the body and bounce off of tissue and return to a receiver. Luminescent materials are of worldwide interest because of their unique optical properties. nanoparticles can be used to create medical advances because of their unique qualities and applications. Many kinds of nanoparticles, such as metal, oxide and semiconductor nanoparticles have been used for constructing electrochemical sensors and biosensors, and these nanoparticles play different roles in different sensing systems.
