In this article, we will focus on ‘plasmonics’.

Plasmonics is one of the alternative technologies to electronics and photonics, and has already actually used in some fields.

This article shows you specifically how it is used for what.

Plasmonics is a technology that uses ‘plasmon’

Plasmons have effects such as ‘surface plasmon resonance’ and ‘plasmon absorption’ and are applied to a wide range of things using plasmons.

Plasmon is explained in the following article, which you can read if you want to know more about the detailed principles.

What is plasmon? This article provides an easy-to-understand explanation of the principles and how they are used in society.

In the past, the world has used ‘electronics’, and it is said that in the next era ‘photonics’ will be the mainstream.

However, handling light is more difficult than with electrons and has only been put to practical use in a few fields.

Such an existence between electronics and photonics is what ‘plasmonics’ is all about.

The following section looks at how plasmonics is used in society.

How Plasmonics is used in society.

Plasmonics is a technology that is currently used in only a few areas and is expected to be applied in the future.

This section introduces some of the actual and expected future applications of plasmonics.

Surface plasmon resonance biosensor.

Surface plasmon resonance biosensors are already in practical use and enable more accurate measurements than conventional ones.

However, they are difficult to introduce and have not yet been widely used due to their large size and very high cost.

LED luminescence enhancement is expected.

Plasmonics is expected to help enhance LED luminescence.

Surface plasmon-enhanced luminescence is simple and effective, with various applications having been reported.

LEDs (light-emitting diodes) are gradually gaining market share, and have recently been used in traffic lights, and many people may have replaced fluorescent lights in their rooms with LEDs.

The future may soon come when its LEDs are made brighter and more practical by plasmonics.

Various types of sensors

Biosensors were introduced earlier, but plasmonics is also expected to be used in other types.

For example

Sensors for health checks using body fluids such as urine and blood.

Agricultural sensors used to detect pesticides and other chemicals.

Light sensors in light-based equipment.

Plasmonics is still an emerging technology, but once it becomes commonplace, it will lead to more convenient and user-friendly items.

Summary

The key points of this article are as follows

Plasmonics refers to technology using plasmon.

Plasmonics is a technology that lies between electronics and optical engineering.

Currently used in biosensors and expected to be used to enhance LED luminescence and in various sensors in the future.
