Researchers are using plasmonic gold nanoparticles to identify chemicals and biomaterials. In most of these cases, the plasmonic band has shifted due to the specific binding of the molecules to the surface, which is used as a signal for identification. However, in some LSPR studies, the arrangement of nanoparticles is used for identification.
What is the difference between type plasmonic gold nanoparticles?
Due to the unique properties of metal nanostructures, their application in various fields has been studied today. Exacerbation of regional superficial plasmon (LSPR) is one of these special features that has recently attracted a lot of attention. These intensifications are related to Nobel metal nanostructures due to the interaction of light with nanostructures, sharp absorption spectra, and severe scattering peaks at certain wavelengths. The past decade has seen significant improvements in the production of Nobel metal nanostructures, which has led to the development of several LSPR-based science and technology fields. One of them is the detection of molecular interactions near the surface of nanoparticles by displacements in the LSPR spectrum peak. The purpose of this review article is to get acquainted with the design of sensors based on LSPR and the factors affecting it.
Nanoparticles have different types and varieties, one of which is the most widely used and widely used type of copper nanoparticles. Due to its cheapness and availability, it has high sales. They use cosmetic products. Nanoparticle production methods are divided into two general categories: physical techniques and chemical techniques.
In the physical method, solids become smaller pieces and fine grains during the grinding process, and energy resources are required, and one of the most common methods of synthesizing physical nanoparticles is the grinding process. Copper nanoparticles are widely used in medicine due to their disinfection and antibacterial properties. They are also used in the electrical and electronic industries and in the production of various types of wires and nanosensors, and are very popular.
What are plasmonic gold nanoparticles?
Plasmon 1 is actually the excitation of a mass of electron gas from a conductive substance by radiation. The conductive material in its conductive layer has an electron sea. These electrons have little interaction with the nucleus, they are actually like gas molecules that move freely, so they are called electron gas. Metals are the best producers of plasmon, because the density of free electrons in their motion is high. If the stimulus occurs in the area near the metal surface, they are called surface 2 plasmons. Light can be paired with these plasmons. A partial surface plasmon that has a smaller size than the wavelength of light (their ratio of the radius to the wavelength (R / λ) is less than 0.1) is called the surface region 3 plasmon. In fact, the cumulative oscillation of the free electrons of nanoparticles produces the regional plasma.
Regional surface plasmons have two important effects. The first effect is an increase in the electric field near the surface of the nanoparticles, which decreases rapidly with distance from the surface of the electric field. The second effect is that the light passing through the particles has a maximum frequency of Iranian plasmonic gold nanoparticles intensification that occurs for intermediate metals at visible wavelengths. This passing peak depends on the refractive index of the surrounding environment.
