Poly(lactide)s [i.e. poly(lactic acid) (PLA)] and lactide copolymers are biodegradable, compostable, producible from renewable resources, and nontoxic to the human body and the environment. They have been used as biomedical materials for tissue regeneration, matrices for drug delivery systems, and alternatives for commercial polymeric materials to reduce the impact on the environment. Since ste...

Objective(s): Nanocomposite active packaging systems were used to prepare antimicrobial and antifungal properties. This study was to investigate the physical and antimicrobial activity of prepared films against three types of aflatoxin producing fungi Aspergillus Flavus. Material and methods: For investigating the effect of antibacterial nano-covers, the direct contact of 0, 1%, 3% and 5%...

The synthesis of a family of new poly(lactic acid-co-glycerol monostearate) (PLA-PGC18) copolymers and their use as biodegradable polymer dopants is reported to enhance the hydrophobicity of poly(lactic acid-co-glycolic acid) (PLGA) nonwoven meshes. Solutions of PLGA are doped with PLA-PGC18 and electrospun to form meshes with micrometer-sized fibers. Fiber diameter, percent doping, and copolym...

Introduction: The treatment of sagging skin in body areas is still a big challenge, as there are few aesthetic procedures aiming to improve it. The poly-L-lactic acid (PLLA) is an injectable synthetic polymer of the alpha-hydroxy acids family, which injection into the deep dermis or superficial hypodermis induces a local and gradual reaction, with synthesis of new collagen by the fibroblasts an...

Introduction: Failure of human body tissue and organs is believed to be one of the most important health problems all over the world. The great challenge for tissue engineers is to optimize suitable systems to separate, proliferate and differentiate the cells so that they can set out to create tissue by a harmonic 3-D growth. Therefore, the tissue engineers must provide an environment like the ...

Targeted drug delivery to endothelial cells lining the vasculature can improve treatment of many pathologies. Intercellular adhesion molecule-1 (ICAM-1), a transmembrane glycoprotein overexpressed in many diseases, is a good determinant for endothelial targeting of drug nanoparticles (NPs). In this study we synthesized surfactant-free, FITC-labeled poly(lactic-co-glycolic) acid (PLGA) NPs coate...
