Julia set fractal
Julia set fractal was taken as a model for
infection dissemination process. The central
larger part of the fractal cluster denotes the
place where the viral infection was
introduced. It is seen quite well that the ways
of infection dissemination over the substrate is
chaotic but also deterministic as well.
3
Self-similarity of Julia set fractal as a model
of viral infection
Demonstration of the object's and projection's
fractal dimension equivalence.

Difference in optical densities in non-infected
HEP-2 cells and infected cells as seen in
luminescent microscope
NON-INFECTED HEP-2 CELLS
INFECTED HEP-2 CELLS
It is obvious that introduction of the virus into
the cells nucleus leads to the significant
increase to the optical density and thus to the
changes in the diffraction pattern.
5
General view of the fractal microscope kit
We use 5 mW He-Ne unimode laser as the source of
coherent radiation. The use of this type of
radiation results in the speckle-type of
diffraction pattern which presents the optical
Fourier transform of the object and, thus,
contains a lot of information about objects
structure which could be extracted using
mathematics.
6
The diffraction pattern as seen along the laser
beam propagation direction.
  • It is quite obvious that the geometrical
    magnification (limited by the devices size only)
    could be made easily enough of about 1000x
    without any complications caused by immersion
    procedure.
  • This figure describes the diffraction pattern
    character which is transmitted into computer for
    further processing with the use of problem
    oriented original software.

Brief technology description
  • Developed a new Fractal Microscopic System
    (FMS) for continuous monitoring of the tiniest
    changes of an objects optical density. FMS
    provides a quantitative view of virus-cell
    interactions in a time-series of frames at any
    stage of the interaction. The FMS is useful in
    life sciences and drug design, in agriculture and
    veterinary sciences, in physics of liquid
    crystals and surface phenomena, in polymer and
    colloid chemistry

What does a fractal image tell scientist ?
  • The fractal image after processing makes it
    possible to estimate the size of the minimal
    cluster composed by the units under consideration
    (e.g. cells, nuclei or viruses) and the fractal
    dimension D of the cluster itself which
    demonstrates the level of the space filling as
    well as the cluster progress.
  • In one example, we have shown that the
    intra-spinal brain fluid has liquid crystalline
    properties and forms a fractal cluster. The
    clusters fractal dimension was changed as a
    result of brain trauma and the recovery process
    was accompanied by the changes of the fractal
    dimension. The treatment of the trauma enhanced
    the rate of the fractal dimension changes.
  • Another experimental application of the fractal
    microscope is with leukemia blood serum samples.
    The normal serum had distinctively other values
    of the fractal dimension than that taken from the
    leukemia patient. The treatment of the leukemia
    case demonstrated the changes in fractal
    dimension towards normal values of this system
    parameter.

Innovative Aspect and Main Advantages
  • The FMS is based on the fractal structural
    properties of an objects organization. The
    computerized fractal microscope could take frames
    of any nano-scale process, monitoring it in real
    time. The FMS has numerous benefits compared with
    the standard techniques, such as the direct
    infected cells luminescent microscopic counting
  • It is a better and simpler way of providing a
    quantitative description,
  • It provides an objective quantitative numeric
    measurement,
  • It gives in-line quick monitoring of virus-cell
    interaction could be realized at any stage.

10
Problem Description Market Need
  • The problem is to elaborate and introduce a new
    original effective device for virus-cell
    interaction monitoring at every stage beginning
    from the very first ones (especially in the cases
    of emergency).
  • The starting market are the international
    pharmaceuticals drug design centers interested
    in express analysis of the drug efficacy
    evaluation as well as clinical laboratories all
    over the world.
  • The potential market is very wide and includes
    firstly the healthcare systems of developing
    countries which need urgently the portable device
    for field antiviral detection and research.

11
Areas of Application
  • Applications of FMS to life sciences and drug
    design
  • For anti-viral applications FMS provides a
    quantitative view of the virus-cell interaction
    in a time-series of frames at any stage of the
    interaction,
  • For detecting viral infections of the animal
    semen during artificial insemination,
  • Applications to agriculture and veterinary
    sciences
  • Food and drug quality monitoring,
  • Viral infection transfer monitoring in domestic
    animals and wild nature.
  • Applications to surface science phenomena
  • For organic materials water dissolution limits
    establishment,
  • For chain polymerization process monitoring and
    for production of polymers,
  • For problems of surface and interface exchange in
    physics and physical chemistry,
  • Self-organization and clusterization control in
    nano-technologies.

12
CONCLUSIONS
  • As the result of the theoretical discussion of
    the real experiment, we would like to state the
    following
  • The possibility of the fractal approach
    application to the problem of virus-cell
    interaction is comprehensively based on the
    platform of modern coherent optics, mathematics
    and computer science.
  • The use of the proposed approach has a lot of
    benefits as compared to the standard techniques,
    especially due to its better and simpler way of
    the quantitative, objective and express type of
    virus-cell in-line interaction monitoring.
  • The fractal approach could be used widely with
    the purpose of virus-cell interaction every stage
    details' evaluation and it will allow, in
    perspective, the perpetual dynamic monitoring of
    the processes on the molecular level of
    self-organization.
  • The proposed fractal approach is mainly
    applicable in laboratory and clinical antiviral
    research as well as in drug design and testing
    process due to its attractive abilities of high
    sensitivity, express character and numerical way
    of data processing.

13
STAGE of DEVELOPMENT

    tested. It is ready for presentation and
    metrological procedures.
