The objective of this study was to optimize the physicodynamic conditions of polymeric system as a coating substrate for drug eluting stents against restenosis. As Nitric Oxide (NO) has multifunctional activities, such as regulating blood flow and pressure, and influencing thrombus formation, a continuous and spatiotemporal delivery of NO loaded in the polymer based nanoparticles could be a via...

The ability to reproducibly produce and effectively collect electrosprayed polymeric microspheres with controlled morphology and size in bulk form is challenging. In this study, microparticles were produced by electrospraying polycaprolactone (PCL) of various molecular weights and solution concentrations in chloroform, and by collecting materials on different substrates. The resultant PCL micro...

Poly(methyl methacrylate) (PMMA) bone cement has limited biocompatibility. Polycaprolactone (PCL) electrospun nanofiber (ENF) has many applications in the biomedical field due to its excellent biocompatibility and degradability. The effect of coating PCL ENF on the surface topography, biocompatibility, and mechanical strength of PMMA bone cement is not currently known. This study is based on th...

Abstract Novel bio‐based, biodegradable packaging material was developed with multi‐functional properties of good mechanical strength, potent biocompatibility, and antifungal attributes, predominantly against fungi vital in food spoilage. Biodegradable polymer composites were prepared a natural agent, nystatin (Nyst), by melt processing technique for the first time. Initially, Polycaprolactone ...

• Wound dressing with Janus superhydrophilic/superhydrophobic feature is designed. Superhydrophilic PCL-Gelatin fibers act as a pump-like suction layer. Suprehydrophobic side shows excellent anti-adhesion effect. Rational design of new wound materials aims to accelerate healing. Traditional hydrophilic dressings, however, tend cause retention exudate retention, which increases the risk bacteria...

Developing biomaterials for tissue regeneration is a promising alternative the recovery of various tissues, including bone. Atorvastatin (ATV) has series beneficial effects which includes bone anabolism, vasodilating, and anti-inflammatory actions. The main objective this work was to produce characterize polycaprolactone (PCL) matrices incorporated with ATV. Samples were prepared by solvent cas...

Cartilage defects are a major health problem. Tissue engineering has developed different strategies and several biomaterial morphologies, including natural-based ones, for repairing these defects. We used electrospun polycaprolactone (PCL) and starch-compounded PCL (SPCL) nanofiber meshes to evaluate extracellular matrix (ECM) formation by bovine articular chondrocytes (BACs). The main aim of t...

The antibiotic, gentamicin sulphate (GS), was incorporated in gravity-spun polycaprolactone (PCL) fibers by spinning from particulate suspensions of the drug in PCL solution to produce a controlled delivery system. The production rate of GS-loaded PCL fibers was confined to the range 1-1.5 m/min and the fiber diameter to 170-220 microm. The kinetics of drug release could be adjusted by varying ...

Nanofibres functionalised with pH-sensitive dyes could greatly contribute to the development of stimuli-responsive materials. However, the application of biocompatible polymers is vital to allow for their use in (bio)medical applications. Therefore, this paper focuses on the development and characterisation of pH-sensitive polycaprolactone (PCL) nanofibrous structures and PCL/chitosan nanofibro...

INTRODUCTION In recent years there has been a steep increase in the number of orthopedic patients for many reasons. One major reason is osteomyelitis, caused by pyrogenic bacteria, with progressive infection of the bone or bone marrow and surrounding tissues. So antibiotics must be introduced during bone implantation to avoid prolonged infection. AIM The objective of the study reported here w...
