What is applied to microorganisms to make them easier to observe?
Aniline dyes and fluorescent dyes are both used.
Why microbiologists use stains on cells?
Basic dyes have positively charged chromophore; thus, there target of binding affinity is the specimen or the microorganism which has a negatively charged cell wall. Through this, basic dyes can penetrate and making it an efficient stain for microorganisms.
Why do bacteria tend to stain better with cationic dyes?
Cationic dyes are positively charged, bacteria must have negatively charged dyes on their surface to attract.
What are the two principal functions of dyes in media?
dyes are used for staining and killing microbes
What one of these leucocytes stain both acidic and bacic dyes?

What makes a color fluorescent?
Fluorescent colors contain pigments or dyes that can absorb and emit light at specific wavelengths. They often contain fluorescent dyes that are able to absorb ultraviolet light and then re-emit it as visible light, resulting in the vibrant and intense colors that we perceive as fluorescent. The absorption and emission properties of these dyes are what give fluorescent colors their characteristic brightness and glow.

How do you improve the color fastness to sweat light of the flame retardant fabric?
The color fastness to sweat light of vat dyes is related to its structural features. The vat dye molecules have not the water soluble group, less polar group and the the synthetic perspiration group have a little effect on the structure of it. The huge closed conjugate system give it high resistance to the light continuously. As we all known, the cost of vat dye is higher than the reactive dye, which with high requires for the dye process control. So only in case of the high requires of the color fastness to sweat light, the vat dyes can be used for replacing some of the reactive dyes. 1. The color fastness to sweat light of the reactive dyes have the characters of reasonable sweat composition, easy test operation, strict standard and with the practical value. 2. Among the three-primary colors of the reactive color, the yellow primary color is better, the red is middle and the green is bad. 3.The flame retardant fabric processed with the green vitriol, the color turn yellow, with CuSO4, the color turn red, which two have little influence to the color fastness to sweat light. 4. Some of the light fastness khan agent and the anti UV agent can improve the color fastness of reactive dyes. 5. To direct fast dye for the medium and light color, the color fastness to light and sweat light is not high, wet color fastness is not as good as the reactive dyes, which can't replace the reactive dyes with low color fastness to sweat light. 6. Some of the sulfur dyes have good color fastness to sweat light, which can be used for reference. 7. The color fastness to sweat light of the vat is good, which can replace the reactive dyes with middle and low color fastness to sweat light, which is an important method to improve the color fastness to sweat light. In conclusion, the method to improve the color fastness to sweat light is, to choose the reactive dyes with high color fastness or choose the vat dyes and some of the sulfur dyes. In the actual production, we should choose according the requires of the color fastness, production cost and the technic. By YULONG tex
