Cyanine
Cyanine is a non-systematic name of a synthetic dye family belonging to polymethine group. The word cyanin is from the English word “cyan", which conventionally means a shade of blue-green (close to "aqua") and is derived from the Greek “kyanos" which means a somewhat different color: "dark blue".
Cyanines were and are still used in industry, and more recently in biotechnology (labeling, analysis). Cyanines have many uses as fluorescent dyes, particularly in biomedical imaging. Depending on the structure, they cover the spectrum from IR to UV. There are a large number reported in the literature.
Structure
There are three types of cyanines:
where two nitrogens are joined by a polymethine chain. Both nitrogens are each independently part of a heteroaromatic moiety, such as pyrrole, imidazole, thiazole, pyridine, quinoline, indole, benzothiazole, etc.
Cyanine dyes history, and use in industry
Cyanines were first synthesized over a century ago. They were originally used, and still are, to increase the sensitivity range of photographic emulsions, i.e., to increase the range of wavelengths which will form an image on the film, making the film panchromatic. Cyanines are also used in CD-R and DVD-R media. The ones used are mostly green or light blue in color, and are chemically unstable. This makes unstabilized cyanine discs unsuitable for archival CD and DVD use, as they can fade and become unreadable in a few years, however, recent cyanine discs contain stabilizers that slow down the deterioration significantly. These discs are often rated with an archival life of 75 years or more. The other dyes used in CD-Rs are phthalocyanine and azo.

Inner Light
by: Zion I[Intro]
And the time says... [x2]
[Verse 1: Zion I]
I'm like Golgo 13 assassinator
Known to those zones microphones and faders
I slip into
Where you've never been to
Come through and witness God within you
I think you
Really like what you see
In your inner most depths the rest is poetry
And it's spoken
From the city of Oakland
Where the flames is hot and rocks be smoking
No jokin
We begin to speak
With the word on the street vibrate to concrete
As a basis
Foundations we create this
Watch for what you wish God will assist
All endeavors
Thoughts like feathers
To carry the bird within your soul to the ethers
Always and forever
I still be
In the place with the grace
Do you feel me
We'll be on the run for the new sun
Til the last day when armaggedeon come
Armaggedeon come... [x2]
[Hook:]
Life is one big road with lots of signs
(scratching: manifestation)
If you relax yourself and just chill you can take the time...
(Relax your mind)
To be yourself and free your mind...
(scratching: elevation)
And when you do it right...
You know your inner light shines
Your light shines... [x3]
(scratching)
(This ain't no game this is life)
[Verse 2: Zion I]
In the middle of the night
I rhyme right
While my man Amp whippin up the beat sham
To inspire we set flames higher
Callin up the spirit talkin on a live wire
Just for the conflict
Just for the place
Just for the days when I was a mental slave
Allow my mind to climb when I ride mics
Take flight jump up withcha satellite
And get high from the soul less shower
Creator is the power
Destruct and devower
I'm on a Timex and my concepts
Better represent what I want to come at cha
Don't got time to play for this worktime
Everyday I gotta pray for the sunshine
Take time
Illuminate self divine
In a little time realize one mind
Yo...
[Hook:]
Life is one big road with lots of signs

You know your inner light shines
Your light shines... [x5]
[Outro:]
This ain't no game this is... life [x2]
(scratching)
This ain't no game this is... [x2]
(scratching)
This ain't no game this is... life
I'm like Golgo 13 assassinator...
Assassinator... [x2]
And the time says... [x2]
In your inner most depths the rest is poetry...
