According to a study by Swedish company Insplorion and innovation consultancy RISE Acreo, local surface plasma resonance (LSPR) technology is expected to produce a large number of low-cost nanosensors in battery monitoring, biosensing, and other applications.
The researchers' preliminary study, "Miniaturization of a nanosensor system for batteries," validated the possibility of creating a low-cost fiber sensor system, which is expected to meet battery monitoring and in vivo diagnostics. Needs for other applications such as manufacturing and process industries. Researchers used Insplorions' NPS technology for this research. The technical basis of NPS lies in the use of the so-called 'local surface plasmon resonance' (LSPR) physics.
The purpose of this study is to explore the design of NPS-based optical fiber sensor systems and to realize the possibility of mass production at low cost.
Insplorion CEO Patrik Dahlqvist stated: 'The important conclusion of this research project is to prove that we can use a large number of components to achieve a competitive manufacturing price, and understand how it can be scaled up in large-scale manufacturing. We can be the first batch suitable for niche type applications. The battery creates an inexpensive sensor system. However, this also requires the development and validation of some technologies to create a sensor system that enters a wide range of markets. ' The LSPR technology is a coherent collective spatial oscillation of conducting electrons in metallic nanoparticles. It can be directly excited by near visible light. The resonance conditions (ie, the wavelength/color of light that can excite the LSPR) are defined by various combinations of the electronic properties of the nanoparticles, their size, shape and temperature, and the dielectric environment near the nanoparticles.
Nano-Plasma sensing with metal nanoparticles (usually silver or gold) as a local sensing element, provides a unique combination of properties; including high sensitivity, small sample size / volume (depending on the size of the sensor nanoparticles, typically about 50 -In the 100nm size range), and the ability to achieve fast, instant (millisecond time resolution) remote reading.
In Insplorion wafer NPS application architecture patent, the sensing is achieved through an array of nano-fabrication on the same transparent substrate a metal of non-interactive Nanodiscs then use the sample material deposited thereon (e.g., nanoparticle film) the dielectric spacer layer film (only several tens of nanometers) covering the metal disk array (sensor). sensor nanoparticles are then embedded in the sensor, in addition to via dipole LSPR off, not physically with each other studied nanomaterials The role of the latter penetration through the spacer layer, and its surface and its surface near the presence of considerable strength, so the location of the dielectric changes can be sensed.
The research company Future Market Insights stated that the global surface plasmon resonance market is expected to grow at a compound annual growth rate (CAGR) of 6.3% between 2017 and 2027, and will reach nearly $1.3 billion in revenue by 2027. To achieve higher levels The demand for high-end, surface plasmon resonance from end-users such as hospitals, clinics, outpatient surgery centers, nursing centers, and reference laboratories continues to increase in terms of productivity and performance. This will provide opportunities for the long-term use of surface plasmon resonance technology and promote further The growth of.
The imaging system will be one of the largest market segments, not to mention the trend of replacing label detection technology with more and more label-free detection technologies. Others are also expected to have significant growth in the market segment as biosensors.
A recent application emphasizes research from Soochow University in China, which uses LSPR technology for smart windows, enabling it to adjust characteristics in response to environmental conditions without any need for manual intervention. This study is based on thermochromic materials. The adaptive behavior can change color in response to temperature changes. The prototype wisdom window uses LSPR to convert photons from ambient sunlight into local thermal energy. This triggers the thermochromic window to switch from transparent to opaque to block further sunlight from entering.
