Environmental concerns are pushing industries for the use of renewable and bio-based materials. Considerable interest has been devoted to poly(lactic acid) (PLA) since this polymer has shown promising and excellent results in mechanical and environmental properties. Poly(lactic acid) properties can be improved by incorporation of nanoplatelets , nanofibers, nanocrystals and nanoparticles into polymer matrix. The reinforcement of poly(lactic acid) using these methods has attracted more researchers with the goal of making "green-nanocomposites" due to their extensive and potential applications....

Unter Nanofasernetzen versteht man Strukturen aus ultrafeinen Polymerfasern. Aufgrund ihrer Größe im Nanometerbereich mit einem hohen Verhältnis von Festigkeit zu Gewicht eignen sie sich sehr gut als Nanosystem zur Abgabe von Arzneimittelmolekülen. Arzneimittelmoleküle, die sich in Nanofasern vermischen, können durch verschiedene Mechanismen auf unterschiedliche Weise aus der Umgebung freigesetzt werden (Burst-Freisetzung, nachhaltige Freisetzung und einstellbare Freisetzung). Nanofasern können im Rahmen von Strategien zur Steuerung der Freisetzungsrate als geeignete...

Nanofibrous meshes refer to the structures made of ultrafine polymeric fibers. Because of nanometer measure size with an excessive strength/weight ratio, they are actual suitable as a nanosystem for delivering drug molecules. Drug molecules which mixed in nanofibers, can be released from the surrounding environment by means of various mechanisms in different manners (burst release, sustainable release and tunable release). Nanofibers can be used by way of release rate controlling strategies as proper delivery structures for drug molecules. The objective of this review is to highpoint the...

Les maillages nanofibreux font référence aux structures constituées de fibres polymères ultrafines. En raison de leur taille nanométrique avec un rapport résistance/poids excessif, ils conviennent très bien comme nanosystème pour administrer des molécules médicamenteuses. Les molécules médicamenteuses mélangées aux nanofibres peuvent être libérées du milieu environnant au moyen de divers mécanismes et de différentes manières (libération en rafale, libération durable et libération réglable). Les nanofibres peuvent être utilisées dans le cadre de stratégies de...

Nano-fibers have attained great research attention owing to their unique physico-chemical characteristics and broad implementation potential. These one-dimensional (1-D) nano-structures are being increasingly applied in bio-medical fields such as manufacturing the scaffolding materials for regenerate new tissues owing to their great surface area-to-volume ratio, high porosity by interrelated pore-configuration, and the suitable surface structure for cell attachment, proliferation, growth, adhesion, viability and differentiation. Nano-fibrous scaffolds with porous construction can mimic the...
