The Biopharmaceutics Classification System (BCS) is a tool that was created to categorize drugs into different groups according to their solubility and permeability characteristics. Through a combination of these factors and physiological parameters, it is possible to understand the absorption behavior of a drug in th…
The use of nanoparticles as building blocks for the self-assembly of functional materials has been rapidly increasing in recent years. In particular, two-dimensional materials can be effectively self-assembled at liquid interfaces thanks to particle localization and mobility at the interface in combination with tailor…
We have successfully fabricated VO2 nanodevices using a photo-induced phase transition mechanism under an ultraviolet-light (λ = 365 nm, I = 7 μW cm−2). On the obtained VO2 nanowires, the photo-induced insulator-to-metal (IM) phase transition occurred from monoclinic (insulator or semiconductor) to tetragonal (metal)…
A number of medical imaging techniques are used heavily in the provision of spatially resolved information on disease and physiological status and accordingly play a critical role in clinical diagnostics and subsequent treatment. Though, for most imaging modes, contrast is potentially enhanced through the use of contr…
Iron oxide/SnO(2) magnetic semiconductor core-shell heterostructures with high purity were synthesized by a low-cost, surfactant-free and environmentally friendly hydrothermal strategy via a seed-mediated method. The morphology and structure of the hybrid nanostructures were characterized by means of high-resolution t…
Cellulose nanofibers with a size range of 5–100 nm have the potential to be a low cost renewable material that has application in a range of products. However, current chemical methods to produce crystalline nanofibers suffer from low yields and high chemical costs, while mechanical methods require high energy costs.…
The significant role of perovskite defect chemistry brought about by the A-site doping of strontium titanate with lanthanum on high temperature steam electrolysis properties is demonstrated. Solid oxide electrolysis cells based on oxygen-excess La0.3Sr0.7TiO3+δ, A-site-deficient La0.2Sr0.7TiO3 and undoped SrTiO3 perov…
The potential of a novel pH-triggered block copolymer as a promising drug delivery platform for the cancer therapy has been explored. The block copolymer poly(ethylene oxide)-b-poly(glycerol monomethacrylate)-b-poly[2-(diisopropylamino)ethyl methacrylate] herein referred to as PEO113-b-PG2MA30-b-PDPA50 upon dissolutio…
Highly ordered 2D-hexagonal mesoporous silica has been functionalized with 3-aminopropyltriethoxysilane (3-APTES). This is followed by its condensation with a dialdehyde, 4-methyl-2,6-diformylphenol to produce an immobilized Schiff-base ligand (I). This material is separately treated with methanolic solution of copper…
Amino groups were successfully introduced to cellulose paper using a silane coupling technique, through the condensation reaction between Si–OH of the organofunctional silane coupling agent and C–OH of cellulose. The as-prepared paper material, denoted amine-modified paper, had excellent handling convenience and some…
A facile sol–gel approach with a fixed calcination temperature is developed to prepare BiFeO3 (BFO) nanoparticles, and the gel-drying temperature is adjusted to control the appearance of a γ-Fe2O3 parasitic phase. The room temperature ferromagnetism of the samples is strongly dependent on the gel-drying temperature. W…
Here, we present a facile solid phase method for preparing unique, 3D hexagonal boron nitride (hBN) nanoflowers, which are composed of vertically aligned BN nanoflakes. The growth process of BN nanoflowers is well-controlled by appropriately changing the reaction times and can be explained by a delayed-release mechani…
This review highlights the characteristics of the cancer that provide opportunities for drug delivery carriers to target cancer. These opportunities include EPR effect, high interstitial pressure of tumour, low pH of endosomes of tumor cells, overexpressed receptors, angiogenesis etc. Chemotherapy is one of the most i…
In the present study, the effects of covalently functionalized carbon nanotubes (CNTs) decorated with C60 (abbr. C60-d-CNT) on thermal, flame retardancy and mechanical properties of polypropylene (PP) are investigated. Compared with pristine CNTs, the C60-d-CNT is more easily dispersed in the PP matrix through reactiv…
We previously demonstrated that monocyte-macrophage based drug delivery can be applied to a spectrum of infectious, neoplastic, and degenerative disorders. In particular, bone marrow-derived macrophages (BMM) loaded with nano formulated catalase, "nanozyme", were shown to attenuate neuro inflammation and nigrostriatal…
Homogeneous BaTiO3 fine powder has been synthesized at (80°C) by using three different chemical methods using the roots TiCl4, BaCl2 and NaOH or Oxalic acid. The resultant powders were characterized using x-ray diffraction (XRD) to estimate the crystal structure, lattice parameters and the crystallite size to investig…
Type I collagen and gelatin, a derivative of Type I collagen that has been denatured, can each be electrospun into tissue engineering scaffolds composed of nano- to micron-scale diameter fibers. We characterize the biological activity of these materials in a variety of tissue engineering applications, including endoth…
Nanoporous gold (np-Au) represents a novel nanostructured bulk material with very interesting perspectives in heterogeneous catalysis. Its monolithic porous structure and the absence of a support or other stabilizing agents opens up unprecedented possibilities to tune structure and surface chemistry in order to adapt…
Pt nanoparticles have been synthesized at relatively low temperatures in aqueous solution from hexachloroplatinic acid using cellulose nanocrystals (CNXLs) from cotton as reducing agents. The Pt nanoparticles were characterised using X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectroscopy…
We have developed a simple and scalable graphene patterning method using electron-beam or ultraviolet lithography followed by a lift-off process. This method, with the merits of: high pattern resolution and high alignment accuracy, being free from additional etching or harsh processes, being universal to arbitrary sub…
