Article
The antimicrobial action of gold depends on different factors including its oxidation state in the intra- and extracellular medium, the redox potential, its ability to produce reactive oxygen species (ROS), the medium components, the properties of the targeted bacteria wall, its penetration in the bacterial cytosol, the cell membrane potential, and...
Article
The acidic pH of healthy skin changes during wound healing due to the exposure of the inner dermal and subcutaneous tissue and due to the potential colonization of pathogenic bacteria. In chronic non-healing wounds, the pH values vary in a wide pH range but the appearance of an alkaline shift is common. After a wound is incurred, neutral pH in the...

The disposal of single-use personal protective equipment has brought a notable environmental impact in the context of the COVID-19 pandemic. During these last two years, part of the global research efforts has been focused on preventing contagion using nanotechnology. This work explores the production of filter materials with electrohydrodynamic te...
Article
Regional anesthesia is widely used in peripheral nerve block and in neuraxial anesthesia to reduce anesthetics systemic side effects and shorten recovery times. However, when applied as a single injection (e.g., peripheral nerve block) it is limited by the duration of its effect. Herein, we develop a thermoresponsive nanogel based on poly(oligoethy...

The incorporation of plasmonic nanoconstructs in biodegradable polymeric nanoparticles (NPs), together with therapeutic drugs in a controlled procedure is of interest for different applications in Nanomedicine. Advanced hybrid nanomaterials can be engineered by combining the in situ formation of plasmonic palladium nanosheets (NSs) and the proper i...

Photothermal Therapy In article number 2106932, Manuel Arruebo, Victor Sebastian, and co‐workers demonstrate a facile and effective procedure to assemble near‐infrared‐sensitive Pd nanosheets into a drug‐loaded biopolymeric nanoparticle, resulting in an efficient theragnostic vector. This vector is capable of coupling the NIR plasmon resonance abso...

The development of new gene-editing technologies has fostered the need for efficient and safe vectors capable of encapsulating large nucleic acids. In this work we evaluate the synthesis of large-size plasmid-loaded PLGA nanoparticles by double emulsion (considering batch ultrasound and microfluidics-assisted methodologies) and magnetic stirring-ba...

The development of thermoresponsive nanogels loaded with nanocrystals of the local anesthetic bupivacaine nanocrystals (BNCs) for prolonged peripheral nerve pain relief is reported here. BNCs were prepared using the antisolvent precipitation method from the hydrophobic form of bupivacaine (bupivacaine free base). The as-prepared BNCs were used stan...
Article
Opaque PET (Polyethylene terephthalate) was recently introduced as a dairy packaging, mainly for milk bottles. Opaque PET, obtained as PET filled with mineral nanoparticles, allows for a reduction of bottles’ thickness, thus a cost reduction for industrials. For this reason, the use of opaque PET is steadily increasing. However, its recyclability i...
Article
The aim was to improve the processability and reduce the melt viscosity of well‐known nanocomposites based on polyamide 66 (PA66) and carbon nanotubes (CNT), while keeping the good electrical conductive ability gained after the addition of CNT. Thus, a nanocomposite based on PA66 as the thermoplastic matrix and 3% of CNT was selected. At this compo...
Article
Copolymers synthesized from acrylic acid and methacrylic acid used as gastroprotective and mucoadhesive enteric coatings have been used to prepare micro (~2 µm), submicro (~200 nm) and nanoparticles (~20 nm) containing rifampicin to obtain time-controlled drug release kinetics. Different particle sizes and drug release kinetics have been obtained b...

The objective of the present work was to produce gastroresistant Eudragit® RS100 nanoparticles by a reproducible synthesis approach that ensured mono-disperse nanoparticles under the size of 100 nm. Batch and micromixing nanoprecipitation approaches were selected to produce the demanded nanoparticles, identifying the critical parameters affecting t...

Titanium dioxide (TiO2) nanoparticles have recently appeared in PET waste because of the introduction of opaque PET bottles. We prepare polymer blend nanocomposites (PBNANOs) by adding hydrophilic (hphi), hydrophobic (hpho), and hydrophobically modified (hphoM) titanium dioxide (TiO2) nanoparticles to 80rPP/20rPET recycled blends. Contact angle mea...

The development of advanced probiotic delivery systems, which preserve bacteria from degradation of the gastrointestinal tract and achieve a targeted release mediated by pH-independent swelling, is of great interest to improve the efficient delivery of probiotic bacteria to the target tissue. Gram-positive and Gram-negative bacteria models (Lactoba...
Article
Bovine Serum Albumin (BSA) and Horseradish Peroxidase (HRP) have been encapsulated within microparticulated matrices composed of Eudragit RS100 by the water-in-oil-in-water double emulsion solvent evaporation method. Good encapsulation efficiencies were achieved for BSA and HRP, 88.4 and 95.8%, respectively. The stability of the loaded proteins was...

New plastic bottles in opaque PET (polyethylene terephtalate) appeared recently on the market. When their waste is mixed to those of transparent-PET-based, the obtained material cannot be recycled anymore because of a loss of properties. The project has been 65% cofinanced by the European Regional Development Fund (ERDF) through the Interreg V-A Spain France Andorra programme (POCTEFA 2014-2020). POCTEFA aims to reinforce the economic and social integration of the French–Spanish–Andorran border. Its support is focused on developing economic, social and environmental cross-border activities through joint strategies favouring sustainable territorial development. The occurrence of these new packagings creates a threat for the recycling industry, very present in the POCTEFA area. In order to maintain and strengthen this sector, new outputs for the recycling of opaque PET bottles are required. This is the challenge that RevalPET proposes to take up.
