Descrizione generale

Polycaprolactone (PCL) is a semi crystalline hydrophobic biodegradable polyester which finds major applications as a drug delivery agent because of its cost efficiency, high toughness and biocompatibility. PCL possesses some unique properties such as:
  • It degrades slower than other biodegradable polyesters in physiological condition, this property can be exploited in the controlled release of drugs in target tissues over a period of time.
  • Its poor surface wetting and interaction with biological fluids on account of its hydrophobicity leads to poor cell adhesion and proliferation, hence it is blended with other synthetic /natural polymers.

Applicazioni

  • PCL loaded with antibiotics may be used to treat infections of the respiratory tract, like tuberculosis.
  • Investigations were carried out based upon phenotypic responses of human bone marrow mesenchymal cells (hBMSCs) for different ratio of chitosan/ polycaprolactone (PCL) blends.
  • PCL/biomedical ceramic materials have been studied for possible osteo tissue regeneration.
  • Action of PCL/graded insulin/beta-5 glycerophosphate concentrations on osteochondral tissue formation through adipose-derived stromal cell differentiation.
  • Other general uses include:extrusion aid, die lubricant, mold release, pigment and filler dispersion aid and polyester segments in urethanes and block polyesters.
