PlumX: Tuning the tilting of the spiral plane by Mn doping in YBaCuFeO5 multiferroic
The layered perovskite YBaCuFeO5 (YBCFO) is considered one of the best candidates to high-temperature chiral multiferroics with strong magnetoelectric coupling. In RBaCuFeO5 perovskites (R: rare-earth or Y) A-site cations are fully ordered whereas their magnetic properties strongly depend on the preparation process. They exhibit partial cationic disorder at the B-site that generates a magnetic spiral stabilized through directionally assisted long range coupling between canted locally frustrated spins.

Bio-nanocellulose meshes improve hernia repair surgery

Written by Anna on .

Press Links:

Bacterial nanocellulose is an emergent biocompatible natural polymer with increasing applicability in the healthcare sector. A potential innovative application can be found in the design of surgical meshes for the treatment of abdominal hernias. Researchers from ICMAB-CSIC and B. Braun Surgical, a leading manufacturer of medical devices for wound closure, have collaborated to develop a bio-based surgical mesh with this biomaterial. First results from an in vivo animal study yield promising outcomes.

PlumX: Noncovalently Linked Metallacarboranes on Functionalized Magnetic Nanoparticles as Highly Efficient, Robust, and Reusable Photocatalysts in Aqueous Medium
A successful homogeneous photoredox catalyst has been fruitfully heterogenized on magnetic nanoparticles (MNPs) coated with a silica layer, keeping intact its homogeneous catalytic properties but gaining others due to the easy magnetic separation and recyclability. The amine-terminated magnetic silica nanoparticles linked noncovalently to H[3,3′-Co(1,2-C2B9H11)2]− (H[1]), termed MSNPs-NH2@H[1], are highly stable and do not produce any leakage of the photoredox catalyst H[1] in water. The magnetite MNPs were coated with SiO2 to provide colloidal stability and silanol groups to be tethered to amine-containing units.

PlumX: Large-Scale Soft-Lithographic Patterning of Plasmonic Nanoparticles
Micro- and nanoscale patterned monolayers of plasmonic nanoparticles were fabricated by combining concepts from colloidal chemistry, self-assembly, and subtractive soft lithography. Leveraging chemical interactions between the capping ligands of pre-synthesized gold colloids and a polydimethylsiloxane stamp, we demonstrated patterning gold nanoparticles over centimeter-scale areas with a variety of micro- and nanoscale geometries, including islands, lines, and chiral structures (e.g., square spirals).

Limbal Stem Cells on Bacterial Nanocellulose Carriers for Ocular Surface Regeneration

Citation: Small 2021, 2003937
DOI: https://doi.org/10.1002/smll.202003937
PlumX: Limbal Stem Cells on Bacterial Nanocellulose Carriers for Ocular Surface Regeneration
Limbal stem cells (LSCs) are already used in cell‐based treatments for ocular surface disorders. Clinical translation of LSCs‐based therapies critically depends on the successful delivery, survival, and retention of these therapeutic cells to the desired region. Such a major bottleneck could be overcome by using an appropriate carrier to provide anchoring sites and structural support to LSC culture and transplantation.

PlumX: Silicon nanowires as acetone-adsorptive media for diabetes diagnosis
Early detection of diabetes, a worldwide health issue, is key for its successful treatment. Acetone is a marker of diabetes, and efficient, non-invasive detection can be achieved with the use of nanotechnology. In this paper we investigate the effect of acetone adsorption on the electronic properties of silicon nanowires (SiNWs) by means of density functional theory.

PlumX: Impact of Chemical Composition on the Nanostructure and Biological Activity of α-Galactosidase-Loaded Nanovesicles for Fabry Disease Treatment
Fabry disease is a rare lysosomal storage disorder characterized by a deficiency of α-galactosidase A (GLA), a lysosomal hydrolase. The enzyme replacement therapy administering naked GLA shows several drawbacks including poor biodistribution, limited efficacy, and relatively high immunogenicity in Fabry patients.An attractive strategy to overcome these problems is the use of nanocarriers for encapsulating the enzyme. Nanoliposomes functionalized with RGD peptide have already emerged as a good platform to protect and deliver GLA to endothelial cells.
