What are free radicals?
Free radicals are unstable atoms stimulated by the environment.
The most common strong oxidants in the environment belong to the categories of Reactive Oxygen Species (ROS) and Reactive Nitrogen Species (RNS). ROS and RNS are actually free radicals, or derivatives that release free radicals; that is, free radicals are "highly oxidized" substances that exist in the environment. When”free radicals”are controlled, the”oxidizing power” in the environment would therefore be controlled.

Various factors make stable substances into free radicals.
Normal substances
Stable state ex: O2,H2O
Free radicals
Unstable state ex:O2-.,HO
Products using Free Radicals
With their"high oxidizing power", free radicals are often used for disinfection, such as bleach, chlorine dioxide, hypochlorous acid, hydrogen peroxide, ozone and peroxygen compounds, etc. These products including free radicals are also very lethal to organisms besides their oxidation effect.
Therefore, after the water is disinfected, it needs to go through the step of "neutralizing free radicals" to reduce the oxidizing power and reduce the great harm to environmental organisms.
The free radicals from air pollution (PM2.5)
PM2.5 is the suspended particles with a diameter smaller than 2.5 micrometers. Dust, mites, and other small particles can all belong to PM2.5. The toxicity of PM2.5 mainly attributes to the attached substances, such as bacteria, heavy metals, dioxin, and other organic matters.
Free radicals produced by microorganisms
Why is free radicals generated by microorganisms: survival and competition.
Survival: resisting environmental toxins, such as pollutants, antibiotics, and fungicides.
Competition: competing with other bacteria and algae for living spaces.
Survival: resisting environmental toxins, such as pollutants, antibiotics, and fungicides.
Competition: competing with other bacteria and algae for living spaces.
The Toxicity of Free Radicals
The "external" damage of free radicals: Damage the surface cells and respiratory organs of organisms. Free radicals affect biological immune defense and reduce biological survival adaptability.
The "internal" damage of free radicals: Damage lipids, proteins and DNA in organisms, affect the immune system of organisms, and increase the risk of genetic mutations.
Free radicals will cause harm?
"UNDINE" reduces the damage to organisms caused by high oxidizing power in the environment, and accelerates the decomposition of organic matter and toxins.
"UNDINE" effectively improves the health and survival rate of aquatic biota.
Detection of free radicals
Many instruments and methods can detect free radicals. Shengquan Company uses natural fluorescent substances to react with free radicals to enhance fluorescence, and it helps to judge the amount of free radicals based on the fluorescence intensity.
The advantage of this method is that it has high specificity and is relatively unaffected by the external environment. At the same time, the intensity of free radicals can be easily distinguished with the naked eye without tedious processes or expensive equipment.
No fluorescent reaction.
With Fluorescence reaction.
Free Radical Detector (FR DETECTOR) can help
1.
Understand the current water quality of the aquaculture pond.
2.
Determine the appropriate treatment (Is the source of replacement water clean? Is the animal protection product suitable?)
3.
Measure the dosage of animal health products (free radicals will rise when they are excessive)
4.
Help water quality decisions
Free radical detector (FR DETECTOR) is the leading indicator of water quality
The vegetable antidote, UNDINE (Free Radicals Scavenger)
The vegetable antidote, UNDINE is to reduce the environmental free radicals by slowly releasing free radicals.
Botanical
UNDINE is extracted from plants and has better biocompatibility.
UNDINE is a free radical sustained release agent. It has photocatalytic properties and is composed of plant extracts with better biocompatibility.
Slow release
UNDINE slowly releases free radicals and is harmless to environmental organisms.
UNDINE decomposes by light, while slowly generating free radicals, which can decompose harmful substances in the environment or neutralize excessive free radicals in the environment.
Neutrality
Neutralizes pollution and microbes to release toxins rather than destroy pathogenic microorganisms.
Increased free radical concentration is used to decompose and remove harmful substances: when the concentration of free radicals is lowered, the organism can grow healthily in a less stimulating environment.
