The complex of polysaccharides modifying luteinizing hormone is a link in the feedback mechanism between the pituitary gland, reproductive organs and liver. This mechanism is regularly activated, triggering regular processes such as the release of an egg by the ovary. Perhaps some infertility problems in humans are caused by defects in this complex regulatory system.

Biochip for early diagnosis of cancer and not only

For example, in the diagnosis of upper respiratory tract diseases, antibodies or DNA contained in a smear from the patient's oral cavity bind to the molecules deposited on the biochip. After processing, the holes of the biochip, in which such binding occurred, begin to glow.
