Poly(lactic acid) (PLA) Nanofibers for Bone Tissue Engineering

Fibers of Poly (lactic-co-glycolic Acid) / Poly (isoprene) Blend for Application in Tissue Engineering

Tissue engineering can be easily described as the in vitro seeding and attachment of human cells onto a scaffold in order to develop new tissue. The application of polymers as scaffolds may bring interesting properties, such as bioresorbability, biocompatibility, mechanical behavior closer to that presented by the original tissue. Poly (Lactic-coGlycolic Acid) (PLGA) and Poly(Isoprene) (PI) wer...

Analysis of Poly(Lactic-co-Glycolic Acid)/Poly(Isoprene) Polymeric Blend for Application as Biomaterial

The application of renewable raw materials encourages research in the biopolymers area. The Poly(Lacticco-Glycolic Acid)/Poly(Isoprene) (PLGA/IR) blend combines biocompatibility for application in the health field with excellent mechanical properties. The blend was obtained by solubilization of polymers in organic solvents. To investigate the polymer thermochemical properties, FTIR and DSC were...

Functional Properties of Biodegradable Nanocomposites from Poly Lactic Acid (PLA)

Nanocomposite composed of organoclay(Cloisite 20A-C20A) and Poly lactic acid (PLA) was prepared by solvent casting method. Physical, mechanical, thermal, barrier and microstructure properties of the composite were studied. X-Ray diffraction (XRD) patterns and scannin...

Screening of microorganisms for biodegradation of poly(lactic-acid) and lactic acid-containing polymers.

The ability of some microorganisms to use lactic acid stereocopolymers and copolymers with glycolic acid as sole carbon and energy sources was studied under controlled or natural conditions. First, 14 filamentous fungal strains were tested in liquid cultures, adopting total lactic acid consumption, nitrogen source exhaustion, and maximal biomass production as selection criteria. Two strains of ...
