The book "Conductometric methods and devices in biology and medicine" by B. Andreeva is a unique and in-depth study devoted to the application of conductometry in the biological and medical sciences. This publication will become an indispensable assistant for students, graduate students, researchers and practitioners interested in modern methods of analysis and diagnosis. In his book, Andreev examines in detail the principles of conductometry, a method based on the measurement of the electrical conductivity of solutions. This approach is widely used in biology and medicine to analyze biological fluids, determine the concentration of various substances and diagnose diseases. The author shares knowledge about how conductometric methods can help in the study of cellular processes, the interaction of biomolecules and even in the development of new drugs. The book covers a wide range of topics, ranging from the basics of conductometry theory to practical applications in medicine. The reader will be able to learn how conductometric methods are used to diagnose diseases such as diabetes, and how they help in monitoring the condition of patients. Andreev also discusses modern instruments used in this field and their advantages over traditional methods of analysis. This work will be especially interesting for those who are fond of biochemistry, molecular biology and medical diagnostics. Students and graduate students studying these disciplines will find in the book useful information and practical recommendations that will help them in their studies and scientific activities. Practitioners and researchers will be able to use the knowledge gained to improve their methods of work and diagnosis. Andreev, as an author, is known for his deep understanding of the subject and ability to explain complex concepts in simple and accessible language. His writing style combines scientific rigor with fascination, which makes reading not only cognitive, but also interesting. In. Andreev is also the author of other significant works in the field of biochemistry and biophysics, which confirms his status as an expert in his field. The book "Conductometric Methods and Instruments in Biology and Medicine" raises important topics such as innovative approaches to diagnosis, the role of technology in medicine, and the future of biological research.
