MNPs are popular candidates for controlling and probing biological objects with a magnetic force. In the past decade, progress in the synthesis and surface engineering of MNPs has further enhanced this popularity.展开更多

A method of recognition of differences between the norm and pathology is based on analysis of multidimensional patterns of the voltamperogram electrochemical test systems in Electronic formats “language”, “electronic nose”. The basis of such systems is the use of a set (matrix) sensor with completely different characteristics. A. N. Frumkin Institute of Physical Chemistry and Electrochemistry RAS (IPCE) developed a method for multidimensional stripping voltammetry, which allowed you to provide information on biological matter being investigated not as a number, as a response to a single dimension, and in the form of N-dimensional image. Formats are implemented in the process of electrochemical studies of liquid or gaseous phase. Evaluating the closeness of the resulting image object under test with known samples is collected in a database. Examples of express diagnostics of glaucoma are with accordance of the results of the electrochemical research of blood serum.展开更多

The experimental results show that the intensity of the reflectance for the index finger is related to age and the smoking circumstance. It was shown that reflectance for the index finger nonlinearly increases and reaches the maximum at about 31 - 32 age for nonsmoker age. Index finger reflectance between smoker and nonsmoker was compared. It was observed that smokers’ index finger reflectance is significantly greater compared with the index finger reflectance for nonsmokers.展开更多
