• The major objective of this project is to
  fabricate a polymer network on the cylindrical
  side-surface of an optical fiber core. The
  mechanism of controlled polymerization by
  evanescent waves has been studied to demonstrated
  that an optical fiber with open side surface of
  its core connected to a spectrometer is an
  apparatus for polymerization and analytical
  device in one.
• Other outcomes from the project include

• light emitting polymer, cross-linked around a
  fiber core, is a prerequisite for an optically
  pumped organic laser (energy-efficient lighting)
• cross-linked polyelectrolyte on a fiber core can
  work as a hydrogen storage container with a high
  ionic capacity and spectroscopic control of
  accumulation and release of hydrogen ions
  (alternative energy source)

• temperature sensitive hydrogel supported by fiber
  core can selectively absorb light of different
  spectral composition the higher the
  temperatures, the wider is the spectral range of
  absorption (scattering in the whispering-gallery-m
  ode)

• cylindrical polymer network itself is a
  prerequisite for a supported 2D-single
  macromolecule with the worlds highest level of
  expansion and contraction, the most sensitive
  externally induced mass transfer, and the record
  fastest response to different stimuli (energy
  conversion)

• chemical and biological specificity of the
  polymer determines the diversity of practical
  applications, such as
• cushion between wet living entities, like
  cells, organelles, liquid media of human body,
  etc., and solid compartments of
  microelectronics or spectroscopic devices a
  hydrogel is wet enough to keep the living
  entities alive and is solid enough to support
  them on a microchip (signal and energy
  transduction)
• spectroscopy of single cell, organelle, or
  microorganism (biofuel)
