Natural bone consists of hard nanostructured hydroxyapatite (HA) in a nanostructured protein-based soft hydrogel template (ie, mostly collagen). For this reason, nanostructured HA has been an intriguing coating material on traditionally used titanium for improving orthopedic applications. In addition, helical rosette nanotubes (HRNs), newly developed materials which form through the self-assemb...

Biofilms are surface-attached microbial organizations, where species enclosed in an exo-polysaccharides matrix. Its removal/prevention from surfaces represents important challenge and a relevant issue many fields. In this light, antimicrobial peptides (AMPs) represent good candidates to conventional antibiotics due their selectivity towards targets (cell membranes), rapid action low tendency in...

This paper reports an "all in one" procedure to produce mesoporous, micro-spherical LiFePO₄ composed of agglomerated crystalline nanoparticles. Each nanoparticle is individually coated with a thin glucose-derived carbon layer. The main advantage of the as-synthesized materials is their good performance at high charge-discharge rates. The nanoparticles and the mesoporosity guarantee a short bulk...

Controlled release of drugs from nanostructured functional materials, especially nanoparticles (NPs), is attracting increasing attention because of the opportunities in cancer therapy and the treatment of other ailments. The potential of magnetic NPs stems from the intrinsic properties of their magnetic cores combined with their drug loading capability and the biochemical properties that can be...

We report ultrasensitive and label-free detection of 2,4,6-trinitrotoluene (TNT) deposited by drop coating using deep-ultraviolet surface-enhanced resonance Raman scattering (DUV-SERRS). Well-defined aluminum nanoparticle arrays as the SERRS substrate at 257 nm excitation wavelength enabled highly reproducible and real-time detection of TNT down to the detection limit of the attogram level in q...

An ITO substrate with periodic surface nanostructures was used to induce strong diffusion and diffraction of incident light. The nanostructures were fabricated using nanoimprint lithography on photoresist followed by coating of the ITO layer and organic materials with uniform morphology. The nanostructures embedded into the ITO layer were found to increase absorption in poly(3-hexylthiophene):[...

Abstract We elaborated a technique of pulsed laser ablation in gas mixtures (He-N 2 ), maintained under residual pressures 0.5–5 Torr to deposit silicon (Si)-based nanostructured films on substrate. show that the deposited can exhibit strong photoluminescence (PL) emission with position peaks depending pressure ambient and ratio gases mixture. Nanostructured prepared pure He exhibited band infr...

The research focuses on the development and optimization of ifosfamide nanostructured lipid carriers for oral delivery with the application of response surface methodology. The objectives of the study were to develop a formulation for ifosfamide to be delivered orally, overcome the instability of the drug in acidic environment during oral administration, to sustain the release, drug leakage dur...
