Size Effect in Hybrid TiO2:Au Nanostars for Photocatalytic Water Remediation Applications
(MDPI, 2022-11-08)
TiO2:Au-based photocatalysis represents a promising alternative to remove contaminants of emerging concern (CECs) from wastewater under sunlight irradiation. However, spherical Au nanoparticles, generally used to sensitize ...
Functionalized Fluorescent Silica Nanoparticles for Bioimaging of Cancer Cells
(MDPI, 2020-09-29)
Functionalized fluorescent silica nanoparticles were designed and synthesized to selectively target cancer cells for bioimaging analysis. The synthesis method and characterization of functionalized fluorescent silica ...
Functionalization of Photosensitized Silica Nanoparticles for Advanced Photodynamic Therapy of Cancer
(MDPI, 2021-06-21)
BODIPY dyes have recently attracted attention as potential photosensitizers. In this work, commercial and novel photosensitizers (PSs) based on BODIPY chromophores (haloBODIPYs and orthogonal dimers strategically designed ...
Development of Kraft Lignin Chemically Modified as a Novel Crosslinking Agent for the Synthesis of Active Hydrogels
(MDPI, 2021-04-28)
In this research a chemical modification of kraft lignin was carried out using a basic nucleophilic substitution reaction (NSA) in order to functionalize it as a novel crosslinking agent for the synthesis of active hydrogels. ...
Green Alternative Cosolvents to N-Methyl-2-Pyrrolidone in Water Polyurethane Dispersions
(Royal Society Of Chemistry, 2021-06-05)
N-Methyl-2-pyrrolidone is a toxic dipolar aprotic solvent widely used in the synthesis of polyurethane dispersions (PUD). Since legislation strongly restricts this substance, green alternatives are essential. Dihydrolevo ...
Tailored Biodegradable and Electroactive Poly(Hydroxybutyrate-Co-Hydroxyvalerate) Based Morphologies for Tissue Engineering Applications
(MDPI, 2018-08)
Polymer-based piezoelectric biomaterials have already proven their relevance for tissue engineering applications. Furthermore, the morphology of the scaffolds plays also an important role in cell proliferation and ...
Bioactive Coatings on Titanium: A Review on Hydroxylation, Self-Assembled Monolayers (SAMs) and Surface Modification Strategies
(MDPI, 2021-12-31)
Titanium (Ti) and its alloys have been demonstrated over the last decades to play an important role as inert materials in the field of orthopedic and dental implants. Nevertheless, with the widespread use of Ti, ...
pH-Induced 3D Printable Chitosan Hydrogels for Soft Actuation
(MDPI, 2022-02-08)
Three-dimensional (3D) printing represents a suitable technology for the development of biomimetic scaffolds for biomedical and tissue engineering applications. However, hydrogel-based inks’ printability remains a challenge ...
Magnetic properties of permalloy antidot arrayfabricated by interference lithography
(American Institute of Physics, 2019-03)
The interference laser lithography and ion-beam sputtering have been reported. Magneto-optical Kerr effect magnetometry indicated that the sample exhibits four-fold anisotropic behaviour, i.e. different magnetization loops ...
Optimized silk fibroin piezoresistive nanocomposites for pressure sensing applications based on natural polymers
(The Royal Society of Chemistry, 2019-06-01)
Environmental issues promote the development of sensors based on natural polymers which are becoming an area of increasing interest. Piezoresistive sensors based on silk fibroin with carbon nanotubes (CNTs) as fillers were ...
