Electrospun scaffolds of neat poly-ε-caprolactone (PCL), poly-ε-caprolactone/βcyclodextrin inclusion complex (PCL/β-CD) and poly-ε-caprolactone amino derivative inclusion complex (PCL/β-CD-NH2) were prepared by the electrospinning technique. The obtained mats were analyzed by a theoretical model using the Hartree–Fock method with an STO-3G basis set, and characterized by X-ray diffraction (XRD)...
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...
The development of devices to controlled the release drugs are in constant technological innovation. aim is improve on target areas. Poly (ε-caprolactone) (PCL) has been widely investigated because degradation rate, biocompatibility, availability, no toxicity, cost and good adhesion a large number drugs. Thus, present study was associated polymer PCL with antibiotics tetracycline as local deliv...
The purpose of this study was to compare: a new five-layered poly (L-lactide-co-caprolactone) (PLC) membrane and small intestinal submucosa (SIS) as a control in rat urinary bladder wall regeneration. The five-layered poly (L-lactide-co-caprolactone) membrane was prepared by an electrospinning process. Adipose tissue was harvested from five 8-week old male Wistar rats. Adipose derived stem cell...
Partially 2,3-O-methylated amyloses efficiently form inclusion complexes with polytetrahydrofuran and poly(epsilon-caprolactone) by simply mixing them in DMSO-H(2)O (1 : 9) solution, in contrast to the case of the parent amylose in which the corresponding inclusion complexes are only slightly formed.
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...
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...
