Abstract In this work, the fabricated polylactic acid (PLA) and hybrid natural fiber (NF) biocomposites via a melt extrusion method were investigated. NFs from locally grown plants utilized as fillers. Polyethene glycol (PEG) was used plasticizer to improve processability of PLA. The effect PLA/NF biocomposite processing assessed by mechanical characterization (tensile, modulus, strain at break...

Four series of polylactide (PLA) based composite films containing horizontally aligned few layer graphene (FLG) flakes high aspect ratio and adsorbed albumin are prepared. The mechanical thermal properties varies with percentage, dispersion degree size FLG flakes. Great improvement up to 290% 360% tensile modulus strength respectively were obtained for the lateral at 0.17% wt, 60% 80% very well...

Poly(lactic acid) (PLA) is the most promising biodegradable alternative to replace conventionalpetrochemical-based polymers in manufacturing high performance materials. Here we review main methods obtain polylactic acid and briefly discuss its functionalization application field of controlled drug release. We conducted a bibliographic search scientific databases summarized results research carr...

Nucleic acid ligands (aptamers) are potentially well suited for the therapeutic targeting of drug encapsulated controlled release polymer particles in a cell- or tissue-specific manner. We synthesized a bioconjugate composed of controlled release polymer nanoparticles and aptamers and examined its efficacy for targeted delivery to prostate cancer cells. Specifically, we synthesized poly(lactic ...

The aim of our work was to examine the relationship between modifications of the surface of nanocapsules (NC) by adsorption or covalent grafting of poly(ethylene oxide) (PEG), and changes in their phospholipid (PL) content on complement activation (C3 cleavage) and on uptake by macrophages. The physicochemical characterization of the NC included an investigation of their properties, such as sur...

En términos generales, es bien conocida la cualidad que poseen algunos polímeros de cambiar sus propiedades físicas y químicas finales mediante adición nanopartículas a matriz polimérica para producir un material compuesto (MC). Esta investigación está basada en obtención MC partir ácido poliláctico (PLA) nanotubos carbono pared múltiple (NTCPM), muy empleado industria del envasado dispositivos...
