用途与安全性

应用

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.

PCL can form a nanocomposite with graphene for the fabrication of biodegradable systems for bone tissue engineering.

Research applications of this material include:

Tissue engineering scaffolds.
3D Bioprinting.
Drug delivery applications such as sustained release.
