In this study, we developed NIR-light responsive poly (lactic-co-glycolic acid) (PLGA) nanoparticles (NPs) by incorporating the ICG dye for local delivery of small-molecular drugs and therapeutics. Since NIR light...

Abstract Wheat bran (WB) was investigated as potential filler for controlling the plasticizer migration in poly(lactic acid) (PLA)/poly(butylene succinate adipate) (PBSA) binary blends (with 60 wt.% of PLA and 40 PBSA). The process three different biobased biodegradable plasticizers [Triacetin (TA), acetyl tri- n -butyl citrate (ATBC) oligomeric lactic acid (OLA)] adding them at a fixed amount ...

Biodegradable four-arm star-shaped poly(lactic acid) (4sPLA) was synthesized from l-Lactic acid (l-LA) and pentaerythritol (PENTA), the polymerization kinetics studied. The effects of reaction time, temperature molar ratio on 4sPLA were discussed. molecular structure characterized by Fourier transform infrared spectroscopy (FTIR) 1H nuclear magnetic resonance spectra (1H-NMR). results showed th...

The effect of a single and multiple doses of polyinosinic-polycytidylic acid (poly (I). poly(C) on lactic dehydrogenase virus viremia has been studied. A single injection of 200 mug of poly (I)-poly(C) given 6 h before infection with lactic dehydrogenase virus caused a temporary decrease in viremia of about 2.5 log10. Repeated injections of 100 mug of poly(I)-poly(C) every 24 h beginning at -24...

Low-molecular-mass bio-polyesters, such as lactic acid oligomers, constitute a growing category of plasticizers for poly (lactic acid), since they show good compatibility and are respectful the environment. This study focuses on glass transition series oligomers with different molecular weights, aim investigating how their associated dynamics occur. Dielectric calorimetric results combined to m...

Lactic acid, which can be obtained through fermentation, is an interesting compound because it can be utilized in different fields, such as in the food, pharmaceutical and chemical industries as a bio-based molecule for bio-refinery. In addition, lactic acid has recently gained more interest due to the possibility of manufacturing poly(lactic acid), a green polymer that can replace petroleum-de...
