At present, saliva and its properties are being actively studied. Human saliva is a unique biological material that has potential in clinical practice. A detailed analysis of the characteristics and properties of saliva is relevant for diagnostic purposes. In this paper, the properties and characteristics of saliva are studied using optoelectronic methods: dynamic light scattering, electrophoretic light scattering and optical microscopy. Mixed saliva from a healthy patient and patient with diabetes mellitus type 2 was used as an object of the study. The dynamics of the behavior of a healthy and patient with diabetes mellitus type 2 is visible according to the results obtained. All three methods confirm hypothesis of structural changes in mixed saliva in the disease of diabetes mellitus type 2.
Investigation of fullerenol solutions with metal salts (magnesium sulfate and calcium chloride) by the laser correlation spectroscopy is presented. The results of the experimental study are discussed. Some peculiarities of interaction between fullerenol and different metal salts were observed. The results of the experiments revealed that fullerenol can be the chelate ligand that may be useful for medical applications.
