Branched PLGA derivatives with tailored drug delivery properties

Acta Pharmaceutica, 2020
Despite several shortcomings such as extreme hydrophobicity, low drug capacity, characteristic triphasic drug release pattern with a high burst effect, poly(lactic-co-glycolic acid derivatives are widely used in drug delivery.

Interactions, structure and properties in poly(lactic acid)/thermoplastic polymer blends

, 2014
Blends were prepared from poly(lactic acid) (PLA) and three thermoplastics, polystyrene (PS), polycarbonate (PC) and poly(methyl methacrylate) (PMMA). Rheological and mechanical properties, structure and component interactions were determined by various ...

Adherability and weldability of poly(lactic acid) and basalt fibre-reinforced poly(lactic acid) [PDF]

Journal of Adhesion Science and Technology, 2017
AbstractThe adherability and weldability of pure poly(lactic acid) (PLA) and basalt fibre-reinforced PLA were investigated in this research. The joining efficiency rate is introduced as a comparative parameter among different joining processes. In the case of adhesive bonding, 16 different adhesives were used to join specimens together.

Chopped basalt fibres: A new perspective in reinforcing poly(lactic acid) to produce injection moulded engineering composites from renewable and natural resources

, 2012
This paper focuses on the reinforcing of Poly(lactic acid) with chopped basalt fibres by using silane treated and untreated basalt fibres. Composite materials with 5–10–15–20–30–40 wt% basalt fibre contents were prepared from silane sized basalt fibres

pH-Responsive Polyethylene Glycol Monomethyl Ether-ε-Polylysine-G-Poly (Lactic Acid)-Based Nanoparticles as Protein Delivery Systems. [PDF]

PLoS ONE, 2016
The application of poly(lactic acid) for sustained protein delivery is restricted by the harsh pH inside carriers. In this study, we synthesized a pH-responsive comb-shaped block copolymer, polyethylene glycol monomethyl ether-ε-polylysine-g-poly (lactic

Poly-l-lactic acid for HIV-1 facial lipoatrophy: 48-week follow-up

, 2009
OBJECTIVES: Poly-l-lactic acid (PLA) injections modestly increase objectively assessed facial thickness but not facial soft tissue volume (FSTV) over 24 weeks. The durability of this response has not been well defined objectively.

Synthesis and characterization of poly(ester amide) from remewable resources through melt polycondensation

eXPRESS Polymer Letters, 2014
Biodegradable poly(ester amide)s (PEAs) were synthesized from lactic acid and 11-aminoundecanoic acid via melt polycondensation. Molecular weights, chemical structures and thermal properties of the poly(ester amide)s were characterized in terms of gel ...

Effect of Zinc Oxide Addition on Antibacterial Behavior of Hydroxyapatite-Poly lactic-co-glycolic acid Scaffold for Bone Tissue Engineering Applications [PDF]

Biological Journal of Microorganism, 2018
Introduction: Infection after the surgery is one of the problems of bone scaffolds implants which is normally treated by systemic administration of antibiotics. But due to the poor blood circulation in bone tissue, large antibiotic doses are needed which

Effects of Graphene Nanoplatelets and Multiwall Carbon Nanotubes on the Structure and Mechanical Properties of Poly(lactic acid) Composites: A Comparative Study

Applied Sciences, 2019
Poly(lactic acid)/graphene and poly(lactic acid)/carbon nanotube nanocomposites were prepared by an easy and low-cost method of melt blending of preliminary grinded poly(lactic acid) (PLA) with nanosized carbon fillers used as powder.
