LABELLED

LABELLING

A new type of labeling, quantum dot labeling (QD), has draw a lot of attention recently.

QD is a type of fluorescent semiconductor nanocrystals with unique optical and electrical properties due to its quantum effect and size effect.

It has been widely used in many fields of life science.

Again

In laser physics, gain or amplification is a process where the medium transfers part of its energy to the emitted electromagnetic radiation, resulting in an increase in optical power.

This is the basic principle of all lasers. Quantitatively, gain is a measure of the ability of a laser medium to increase optical power.
