Supercritical CO 2 blown foams of poly(ε-caprolactone) (PCL) covalent networks are developed through a two-step strategy by taking advantage the thermo-reversible Diels–Alder cycloaddition between furan and maleimide.

In order to expand the properties and applications of aliphatic absorbable polyesters, a new biodegradable block copolymer family, poly(ester amide)-b-poly(ε-caprolactone) (PEA-b-PCL), was synthesized and characterized. These copolymers were synthesized by first preparing l-phenylalanine-based poly(ester amide) macroinitiators (Phe-PEAs) with free amine end groups via a solution polycondensatio...

The present work describes the development and the evaluation of cryogel-poly-ε-caprolactone combinatory scaffolds for bone tissue engineering. Gelatin was selected as cell-interactive biopolymer to enable the adhesion and the proliferation of mouse calvaria pre-osteoblasts while poly-ε-caprolactone was applied for its mechanical strength required for the envisaged application. In order to real...

Thermo-responsive diblock copolymers composed of hydrophilic methoxy poly(ethylene glycol) (MPEG) and hydrophobic biodegradable polyesters were prepared for application as injectable drug delivery systems, because they show a thermo-responsive sol-to-gel transition, especially around body temperature, when dispersed in aqueous solutions. The thermogelling hydrogels formed by hydrophobic aggrega...

Biomedicine requires materials able to respond specific needs without affecting the organism. Organic–inorganic fibrillar polymeric matrices possess unique properties that may fulfill these needs. In present study, different topology-controlled poly(ε-caprolactone)-based containing glycine betaine at varying concentrations (0.5, 1, and 2% w/v) were prepared via electrospinning. The used as subs...

Well-defined graft copolymers were obtained using a copper-catalysed azide-alkyne Huisgen's cycloaddition click reaction from both biocompatible and non-toxic poly(ε-caprolactone) and poly(2-methyl-2-oxazoline) homopolymers. Resulting amphiphilic copolymers proved to form micelles that could be used as potential drug carriers.

In the present study, poly(ethylene glycol)-b-poly(ε-caprolactone) micelles loaded with etoposide (ETO) were formulated and further conjugated with pentapeptide Glu-Ile-Leu-Asp-Val (EILDV) to target α4β1 integrin receptor overexpressed on metastatic tumor cell. Using a distinct ratio of carboxyl-terminated poly(ethylene glycol)-block-poly(ε-caprolactone) (HOOC-PEG-b-PCL) to methoxy-poly(ethylen...
