Monitoring of the environment, chemistry, and biology have all made extensive use of plasmonic sensors. These sensors have found commercial use because of their exceptional sensitivity and surface plasmon resonance (SPR) or localised surface plasmon resonance (LSPR) effects.
The exceptional sensitivity of plasmonic sensors is well recognised in the optical and photonics communities. These sensors take advantage of the amplification and localisation of electromagnetic fields along the interface of a metal and a dielectric.
Surface plasmon polaritons (SPPs), which are coherent electron oscillations that travel alongside an electromagnetic wave along the interface between a dielectric (such as glass or air) and a metal (such as silver or gold), are commonly used in plasmonics.
The Global Quantum Plasmonic Sensor market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Trends of biosensing: plasmonics through miniaturisation and quantum sensing. Due to the increased interest in nano optics, plasmonics and surface plasmon resonance-based biosensors have become increasingly well-liked and are now important in terms of applications related to human health.
Plasmonics have a high sensitivity and meet the criteria for sensitivity, selectivity, and detection limit when utilised in health surveillance systems. Furthermore, integration into microsystems and point-of-care devices has made it possible to achieve notable levels of sensitivity and limit of detection.
Everything mentioned above has aided in the growth of markets for the development of rapid and very sensitive label-free detection. The development of wearable plasmonic sensors and point-of-care applications for a variety of uses reflect the trend, which highlights the potential influence of the new generation of plasmonic biosensors on human well-being through the ideas of personalised medicine and global health.
The performance of recent plasmonic biosensor applications in microsystems is examined. The conclusion focuses on a promising approach for chemical and biological sensing applications: the combination of microfluidics and lab-on-a-chip with quantum plasmonics technology.
Research in the area of quantum plasmonic sensing for biological applications has exploded in an effort to get past the constraints imposed by quantum fluctuations and noise. If correctly utilised, the substantial developments in nanophotonics, plasmonics, and microsystems employed to make increasingly effective biosensors would continue to be advantageous to this discipline.
