FITC (389 g/mol) was one of the first dyes which was used for fluorescence microscopy and served as an origin for further fluorescent dyes like Alexa FluorÂ®488. Its fluorescence activity is due to its large conjugated aromatic electron system, which is excited by light in the blue spectrum.
Body odor is not catching. If the body odor is due to an infection, the infection may be contagious, such as a sexually transmitted disease. Inherited conditions may be passed on to children through the genes.ody odor is the term used for any unpleasant smell associated with a person's body. People usually associate body odor with sweat, but sweat by itself does not give off an odor.
Poor hygiene is one of the most common causes of body odor in kids. Irregular bathing, not washing the armpits and groin region, bacteria accumulated in the clothes can lead to bad odor. If your child refuses to take bath regularly, she might smell when the bacteria on the skin contacts sweat.
