3. LED technology for the analysis of biological fluids
3.1 Optical microtomography for the pattern recognition of biomatters
Human biological fluids (blood, saliva, sweat, urine, tears, etc.) are very sensitive to any
external influences, but their information sensory pattern can be generated by means of our
developed intelligent system “ISLB” with wireless mobile retransmitters. Using received
sensory data of information patterns of biomatters it is possible to produce electronic virtual
and intellect-maps of the quality of alimentary products or environmental conditions for the
maintenance of the human health and the personal and social biosafety. The intelligent
system “ISLB” can define spectral-response characteristics of biomatters, e.g., absorption,
reflection, polarization factors, changes of intensity, phase, and amplitude of an
electromagnetic wave in the broadband frequency range of 10
11
-10
15
Hz. “ISLB” is suited to
be used for the individual application, e.g., in wristwatches, watch and mobile phones,
smartphones, communicators, iPads, PDAs with an embedded software for the purpose of
the continuous maintenance and monitoring of the human health, the prolongation of life
and the improvement of the vital activity [6]. An important advantage of “ISLB” is the fast
recognition of information patterns of biomatters, so there is no need for special conditions
of its functioning and for a remote costly laboratory.
3.2 Blood
If using a mobile device (smartphone, communicator, iPad, PDA, wristwatch, watch or
mobile phone, etc.) with the microsensory system “ISLB” an electromagnetic wave emitted
by the microlight-emitting diode falls on the human skin surface, it is absorbed, scattered
and reflected by this one. (Fig. 14) [1, 6].
The absorption of the radiation arises from the photons interaction with different
chromophores, but scattering is because of changes of the reflection coefficient. There are
some disturbances of the human biosystem, functioning its separate organs and
biochemical processes because of the consumption of poor farming cultures, natural form
foods or food products. Biochemical and spectral characteristics of blood are changed a lot
and individually depending on cognitive and functional states of the human organism [6,
7]. The intelligent system “ISLB” with the developed software enables to maintain in a
real time the personal and social biosafety and the human health. It is known that the
hormone ghrelin is produced in stomach of a hunger man, at its maximum before eating,
and then this one is reduced gradual during a meal. The satiation hormone PPY3-36
affecting hypothalamus is at its highest point after eating, and then this one is decreased
in some following hours slowly [7]. The blood lipidic and carbohydrate composition is
varied because of the nutritive absorption from food after a meal. An increase in the
concentration of glucose in blood during eating results in ceasing neurons with sensing
membrane channels to send signals and generating the hormone orexin which forces the
human organism being awake, eating moderately and self-learning fast. It explains
essential differences of information patterns for a man being hungry and sated (Fig. 15),
excessive somnolence after a meal and the risk taking behaviour of a hunger man. In this
case changes of a level of leukocytes, glucose and whole protein are defined more clearly
in the table 2.
