Encapsulation and storage of therapeutic fibrin-homing peptides using conducting polymer nanoparticles for programmed release by electrical stimulation
(American Chemical Society (ACS), 2020-04-01)
Article
Accés obertCys-Arg-Glu-Lys-Ala (CREKA) is an important fibrin-homing pentapeptide that has been extensively demonstrated for diagnoses and therapies (e.g., image diagnosis of tumors and to inhibit tumor cell migration and invasion). ... -
Biodegradable polylactides scaffolds with pharmacological activity by means of ultrasound micromolding technology
(Multidisciplinary Digital Publishing Institute, 2020-04-29)
Article
Accés obertUltrasound micromolding technology has been applied to get microporous polylactide scaffolds from the subsequent leaching of incorporated NaCl salts. A small amount of water-soluble polyethylene glycol (PEG) was required ... -
Incorporation of chloramphenicol loaded hydroxyapatite nanoparticles into polylactide
(2019-10-02)
Article
Accés obertChloramphenicol (CAM) has been encapsulated into hydroxyapatite nanoparticles displaying different morphologies and crystallinities. The process was based on typical precipitation of solutions containing phosphate and ... -
Electrically polarized hydroxyapatite: influence of the polarization process on the microstructure and properties
(2019-11-19)
Article
Accés obertSemipermanently polarized hydroxyapatite, named SP/HAp(w), is obtained by applying a constant dc electric field of 1–10 kV/cm at 300–850 °C to the samples previously sintered in water vapor, while permanently polarized ... -
Improvement of biodegradability and biocompatibility of electrospun scaffolds of poly(butylene terephthalate) by incorporation of sebacate units
(2020-01-01)
Article
Accés obertIncorporation of aliphatic units to poly(butylene terephthalate) (PBT) gives rise to biodegradable copolymers with tunable properties (e.g., degradability), depending on the selected comonomer and the specific composition. ... -
Amorphous binary dispersions of chloramphenicol in enantiomeric pure and racemic poly-lactic acid: morphology, molecular relaxations, and controlled drug release
(2019-09-10)
Article
Accés obertWe study amorphous solid dispersions (ASDs) of the chloramphenicol antibiotic in two biodegradable polylactic acid polymers, namely a commercial sample of enantiomeric pure PLLA and a home-synthesized PDLLA copolymer, to ... -
Polypropylene mesh for hernia repair with controllable cell adhesion/de-adhesion properties
(Royal Society of Chemistry (RSC), 2020-02-07)
Article
