Liquid crystals as an active medium of enzymes optical sensors

Nonlinear features of the transition of a liquid crystalline mixture into an isotropic state under the action of alcohol vapors

“…Also, based on previous experiments with similar sensors, it can be concluded that changes over time in the process of absorption of evaporated substances are qualitatively the same for all three color curves and to some extent reflect changes in the degree of optical transmittance [19][20][21]. We accept these changes as an analytical criterion for the action of alcohols.…”

Features of the transition to the isotropic state of the liquid crystal sensitive element of the gas sensor under the action of acetone vapor

“…In general, a suitable marker of the disease can be almost any substance that appears outside the normal state in the exhalation gases, is related to the process of a particular disease or pathology, and is available for detection by modern technical means [6][7][8].…”
